  guidance: 'This x402 discovery document lists only active paid Delx routes. Current starting points: generate_image at https://api.delx.ai/api/v1/x402/image for $0.01 USDC; generate_image_budget at https://api.delx.ai/api/v1/x402/image-budget for $0.005 USDC; generate_speech_hd at https://api.delx.ai/api/v1/x402/speech-hd for $0.08 USDC; narrated_post at https://api.delx.ai/api/v1/x402/narrated-post for $0.02 USDC. Use PAYMENT-SIGNATURE after a 402 challenge. REST callers can also use Authorization: Payment <credential> for MPP-compatible retries. OWS can drive the x402 retry flow with a local wallet; see https://delx.ai/docs/ows-setup.'
  x-guidance: 'Use this pay-per-result API without an API key or subscription. First call GET /api/v1/x402/start?q=<intent> to choose the best product, then invoke the exact operation with JSON matching its requestBody schema. Always send header x-delx-source with your skill, pack, or directory id (example: skill-delx-micro-utils) so conversion is attributable. An unpaid call returns HTTP 402 with x402 payment requirements; retry it with Payment-Signature. Low-cost starting points include image generation at $0.01, image resize/conversion at $0.001, QR generation at $0.001, and x402 server audit at $0.01.'

Call for a short social post, announcement, product card, or explainer—not generative motion, timeline editing, captions, music, or a full video-production suite. Returns durable MP4, image, and WAV URLs with SHA-256, actual provider source, cost, and margin receipt; no buyer API key or subscription.'

        summary: 'Lint a text-to-image prompt for length and basic policy tokens before paying. Call when you need this bounded result before handing data to a downstream tool. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Honest limit: execution uses only caller-supplied data in memory; it does not call a paid upstream, retain input, search the web, read a live RPC, or invoke a media generator. Results are advisory; the caller owns authorization, budgets, and production controls.'

        summary: Look up open buyer RFQs for $0.003 USDC. Call when you need live demand with public task contracts, USDC ceilings, deadlines, and acceptance criteria instead of waiting for catalog traffic. Bid separately with a wallet signature; this call never exposes buyer capabilities, encrypted envelopes, raw wallets, or payment proofs and never custodies funds. No API key, no subscription.

        summary: Apply reversible ROT13 to Latin letters while preserving numbers, punctuation, spacing, and letter case for $0.001 USDC. Use it for deterministic fixture decoding, obfuscation compatibility, or legacy text workflows up to 100,000 characters. The first-party transform runs locally with no network call, storage, key, or retention.

        summary: Compare two bounded caller-supplied DNS record snapshots and return canonical added, removed, and unchanged records. Use after repeated DNS or MX inspections to detect an infrastructure change without another parser. Returns deterministic JSON for 0.001 USDC via x402 on Base or Solana; local-only, memory-only, and no DNS request is made.

        summary: 'Age Header Validate: checks whether an HTTP Age value fits a declared freshness lifetime using only bounded caller-supplied values. Call when you need a bounded age header validate result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Age Header Validate as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Etag Comparison Mode: evaluates strong or weak comparison between two entity tags using only bounded caller-supplied values. Call when you need a bounded etag comparison mode result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Etag Comparison Mode as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Last Modified Compare: orders two Last-Modified instants and reports their delta using only bounded caller-supplied values. Call when you need a bounded last modified compare result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Last Modified Compare as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Accept Header Rank: ranks offered media types against weighted Accept ranges using only bounded caller-supplied values. Call when you need a bounded accept header rank result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Accept Header Rank as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Accept Language Rank: ranks offered languages against weighted Accept-Language ranges using only bounded caller-supplied values. Call when you need a bounded accept language rank result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Accept Language Rank as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Accept Encoding Rank: ranks supported content codings against Accept-Encoding weights using only bounded caller-supplied values. Call when you need a bounded accept encoding rank result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Accept Encoding Rank as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Content Disposition Parse: extracts disposition type, filename, and safe parameters using only bounded caller-supplied values. Call when you need a bounded content disposition parse result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Content Disposition Parse as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Link Header Parse: parses bounded Link header targets and relation parameters using only bounded caller-supplied values. Call when you need a bounded link header parse result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Link Header Parse as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Forwarded Header Parse: parses bounded standardized Forwarded header elements using only bounded caller-supplied values. Call when you need a bounded forwarded header parse result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Forwarded Header Parse as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'CORS Origin Check: compares a request origin with explicit allowed origins using only bounded caller-supplied values. Call when you need a bounded cors origin check result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for CORS Origin Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'CORS Preflight Check: checks requested method and headers against a CORS preflight policy using only bounded caller-supplied values. Call when you need a bounded cors preflight check result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for CORS Preflight Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'HSTS Policy Check: checks HSTS max-age and subdomain directives against caller policy using only bounded caller-supplied values. Call when you need a bounded hsts policy check result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for HSTS Policy Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'CSP Directive Parse: parses Content-Security-Policy directives into normalized source lists using only bounded caller-supplied values. Call when you need a bounded csp directive parse result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for CSP Directive Parse as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Cookie Domain Match: evaluates host-only or Domain cookie matching for a request host using only bounded caller-supplied values. Call when you need a bounded cookie domain match result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Cookie Domain Match as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Authorization Scheme Identify: identifies an Authorization scheme without exposing or validating credentials using only bounded caller-supplied values. Call when you need a bounded authorization scheme identify result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Authorization Scheme Identify as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Range Header Parse: parses one bounded HTTP byte range into start and end offsets using only bounded caller-supplied values. Call when you need a bounded range header parse result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Range Header Parse as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Redirect Chain Check: checks a caller-supplied redirect chain for loops, downgrade, and hop budget using only bounded caller-supplied values. Call when you need a bounded redirect chain check result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Redirect Chain Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Status Retry Classify: classifies whether a method and status pair is retryable under caller policy using only bounded caller-supplied values. Call when you need a bounded status retry classify result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Status Retry Classify as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Transfer Encoding Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Connection Header Tokenize: normalizes hop-by-hop connection option tokens using only bounded caller-supplied values. Call when you need a bounded connection header tokenize result before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Connection Header Tokenize as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'DNS MX Priority Sort: sorts MX exchanges by preference while preserving equal-priority order using only bounded caller-supplied values. Call when you need a bounded dns mx priority sort result before choosing an MX exchange from caller-supplied preference records. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for DNS MX Priority Sort as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: Detect likely credentials and private keys without returning their values. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base or Solana. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

        summary: Count likely personal-data classes without echoing detected values. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability.

        summary: Turn an OpenAPI document into a compact operation index for planning and tool selection. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base or Solana. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

        summary: Decide whether an HTTP failure is safe to retry and return an idempotency-aware policy. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base or Solana. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

        summary: Calculate a bounded exponential backoff schedule for reliable autonomous retries. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base or Solana. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

        summary: Measure achieved reliability against an SLO target from good and total events. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base or Solana. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

        summary: Calculate p50, p95, p99, mean, min, and max from bounded latency samples. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base or Solana. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

        summary: Normalize JSON or common text logs into one stable event envelope. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base or Solana. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

        summary: Audit a Content-Security-Policy for missing defaults and unsafe script directives. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base or Solana. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

        summary: Derive a deterministic namespaced idempotency key from canonical JSON. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base or Solana. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

        summary: Profile the top-level shape, fields, size, and cardinality of a JSON value. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Measure null and missing-field distribution across JSON records. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Find duplicate record groups using canonical fingerprints without returning record values. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Build a bounded frequency distribution for categorical values. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Detect gaps larger than an expected interval in ISO-8601 timestamps. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Create a stable SHA-256 fingerprint from canonical JSON. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Evaluate data age against a caller-supplied freshness objective. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: 'Count lines in caller-held text with nonempty breakdown. Call when you need this bounded result before handing data to a downstream tool. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Honest limit: execution uses only caller-supplied data in memory; it does not call a paid upstream, retain input, search the web, read a live RPC, or invoke a media generator. Results are advisory; the caller owns authorization, budgets, and production controls.'

Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Honest limit: execution uses only caller-supplied data in memory; it does not call a paid upstream, retain input, search the web, read a live RPC, or invoke a media generator. Results are advisory; the caller owns authorization, budgets, and production controls.'

        summary: 'Ensure a string ends with a required suffix without duplication. Call when you need this bounded result before handing data to a downstream tool. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Honest limit: execution uses only caller-supplied data in memory; it does not call a paid upstream, retain input, search the web, read a live RPC, or invoke a media generator. Results are advisory; the caller owns authorization, budgets, and production controls.'

        summary: Diff path keys between two OpenAPI path maps. Call when detecting added/removed routes between specs. Returns added, removed, common_count as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

        summary: 'JSON Array Dedupe: removes duplicate JSON array values while preserving first occurrence using only bounded caller-supplied values. Call when you need a bounded json array dedupe result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Array Dedupe as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'JSON Array Intersection: returns values shared by two JSON arrays in left-side order using only bounded caller-supplied values. Call when you need a bounded json array intersection result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Array Intersection as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

Call when you need a bounded json array flatten one result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Array Flatten One as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'JSON Array Sort By Key: sorts object rows by a selected top-level key using only bounded caller-supplied values. Call when you need a bounded json array sort by key result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Array Sort By Key as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'JSON Array Group By Key: groups object rows by a selected top-level key using only bounded caller-supplied values. Call when you need a bounded json array group by key result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Array Group By Key as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'JSON Array Index By Key: indexes object rows by a unique top-level key and reports duplicates using only bounded caller-supplied values. Call when you need a bounded json array index by key result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Array Index By Key as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'JSON Array Filter Keys: keeps object rows whose selected key matches caller values using only bounded caller-supplied values. Call when you need a bounded json array filter keys result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Array Filter Keys as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

Call when you need a bounded json object rename keys result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Object Rename Keys as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'JSON Object Lowercase Keys: lowercases top-level keys and reports case collisions using only bounded caller-supplied values. Call when you need a bounded json object lowercase keys result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Object Lowercase Keys as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'JSON Patch Preview: previews bounded add, remove, and replace operations without mutating a source using only bounded caller-supplied values. Call when you need a bounded json patch preview result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Patch Preview as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

Call when you need a bounded json pointer get result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Pointer Get as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

Call when you need a bounded json pointer escape result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Pointer Escape as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'JSON Depth Check: measures JSON nesting depth against a caller budget using only bounded caller-supplied values. Call when you need a bounded json depth check result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Depth Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

Call when you need a bounded json key denylist result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Key Denylist as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention.

        summary: 'JSON Required Fields Check: finds absent or null required top-level fields using only bounded caller-supplied values. Call when you need a bounded json required fields check result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Required Fields Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'JSON String Length Check: checks selected string fields against caller length bounds using only bounded caller-supplied values. Call when you need a bounded json string length check result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON String Length Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

Call when you need a bounded json array length check result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Array Length Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'JSON Numeric Range Check: checks selected numeric fields against inclusive bounds using only bounded caller-supplied values. Call when you need a bounded json numeric range check result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Numeric Range Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'JSON Pattern Fields Check: checks selected string fields against a bounded regular expression using only bounded caller-supplied values. Call when you need a bounded json pattern fields check result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Pattern Fields Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

Call when you need a bounded json cross field order result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Cross Field Order as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'JSON Timestamp Fields Check: checks selected fields as integer epoch seconds within bounds using only bounded caller-supplied values. Call when you need a bounded json timestamp fields check result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Timestamp Fields Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'JSON URL Fields Check: checks selected fields for absolute HTTP or HTTPS URL shape using only bounded caller-supplied values. Call when you need a bounded json url fields check result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON URL Fields Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'CSV Delimiter Detect: scores common delimiters from bounded CSV text using only bounded caller-supplied values. Call when you need a bounded csv delimiter detect result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for CSV Delimiter Detect as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'CSV Column Count Check: checks every CSV row against an expected column count using only bounded caller-supplied values. Call when you need a bounded csv column count check result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for CSV Column Count Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

Call when you need a bounded csv duplicate key check result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for CSV Duplicate Key Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'CSV Sort Rows: sorts bounded CSV rows by one column using only bounded caller-supplied values. Call when you need a bounded csv sort rows result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for CSV Sort Rows as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'CSV Trim Cells: trims surrounding whitespace from every bounded CSV cell using only bounded caller-supplied values. Call when you need a bounded csv trim cells result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for CSV Trim Cells as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

Call when you need a bounded csv join by key result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for CSV Join By Key as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'CSV Left Join By Key: left-joins two bounded CSV tables on one key column using only bounded caller-supplied values. Call when you need a bounded csv left join by key result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for CSV Left Join By Key as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'CSV Pivot Count: builds a count pivot from row and column category fields using only bounded caller-supplied values. Call when you need a bounded csv pivot count result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for CSV Pivot Count as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'CSV Unpivot: converts selected wide CSV columns into name and value rows using only bounded caller-supplied values. Call when you need a bounded csv unpivot result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for CSV Unpivot as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Batch Rate Limit Plan: calculates dispatch duration from request count and rate window using only bounded caller-supplied values. Call when you need a bounded batch rate limit plan result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for Batch Rate Limit Plan as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Batch Retry Partition: partitions batch results into retryable and terminal identifiers using only bounded caller-supplied values. Call when you need a bounded batch retry partition result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for Batch Retry Partition as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Batch Idempotency Keys: derives stable non-secret idempotency keys for batch items using only bounded caller-supplied values. Call when you need a bounded batch idempotency keys result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for Batch Idempotency Keys as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Batch Error Budget Check: checks failed item count and fraction against caller budgets using only bounded caller-supplied values. Call when you need a bounded batch error budget check result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for Batch Error Budget Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Batch Completion Gate: checks terminal item coverage and minimum success fraction using only bounded caller-supplied values. Call when you need a bounded batch completion gate result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for Batch Completion Gate as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: Classify a field-name inventory for likely sensitive data without inspecting values. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Compare declared retention with a maximum policy window. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Check tests, rollback, observability, ownership, and security review before deploy. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Classify operational incident severity from explicit impact signals. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Normalize audit events while hashing the actor identifier. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Compare expected and actual top-level response fields and value types. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Compare requested OAuth scopes with the minimum required scopes. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Recommend a semantic-version bump from explicit change signals. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Evaluate caller-supplied x402 payment requirements before a wallet signs them. Use after receiving HTTP 402 to enforce a maximum USDC amount, allowed networks, exact scheme, recipient presence, and an optional expiry buffer. Returns eligible accepts and explicit blockers for 0.002 USDC via x402 on Base or Solana; it never signs, pays, stores, or echoes a payment signature.

        summary: Screen untrusted text for common cross-site scripting signals without echoing it. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Audit password policy for length, breached-secret checks, and MFA. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Calculate gross profit, gross margin, and profitability. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Calculate static cash runway from cash and monthly burn. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Calculate per-cohort and weighted retention from bounded cohorts. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Calculate LTV-to-CAC ratio with a bounded health heuristic. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Calculate descriptive conversion lift for control and treatment. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Measure top-account and top-three revenue concentration without returning account values. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base or Solana. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

        summary: Constant-product AMM output amount for a given input size. Call when simulating x*y=k swaps offline from reserves you already know. Returns amount out and new reserves as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

        summary: Normalize await/job status fields for media-long jobs. Call when agents polling long jobs need a stable status shape. Returns normalized status object as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

        summary: 'X402 Network Match: compares a challenge network identifier with buyer-supported networks using only bounded caller-supplied values. Call when you need a bounded x402 network match result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Network Match as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'X402 Asset Match: compares a challenge asset identifier with buyer-supported assets using only bounded caller-supplied values. Call when you need a bounded x402 asset match result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Asset Match as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'X402 Amount Budget Check: checks challenge raw amount against an exact buyer call budget using only bounded caller-supplied values. Call when you need a bounded x402 amount budget check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Amount Budget Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

Call when you need a bounded x402 resource match result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Resource Match as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth.

        summary: 'X402 Scheme Select: selects the first buyer-supported payment scheme from challenge options using only bounded caller-supplied values. Call when you need a bounded x402 scheme select result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Scheme Select as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'X402 Accepts Rank: ranks challenge accepts entries against buyer network and asset preferences using only bounded caller-supplied values. Call when you need a bounded x402 accepts rank result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Accepts Rank as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

Call when you need a bounded x402 payment deadline check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Payment Deadline Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth.

        summary: 'X402 Payment Replay Key: derives a stable non-secret replay-detection key from payment metadata using only bounded caller-supplied values. Call when you need a bounded x402 payment replay key result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Payment Replay Key as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'X402 Settlement Network Check: compares settlement chain with the accepted challenge network using only bounded caller-supplied values. Call when you need a bounded x402 settlement network check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Settlement Network Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'X402 Settlement Tx Shape: checks a settlement transaction identifier for expected chain shape using only bounded caller-supplied values. Call when you need a bounded x402 settlement tx shape result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Settlement Tx Shape as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

Call when you need a bounded x402 delivery content type check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Delivery Content Type Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'X402 Delivery Size Check: checks serialized result byte size against a buyer limit using only bounded caller-supplied values. Call when you need a bounded x402 delivery size check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Delivery Size Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

Call when you need a bounded x402 refund eligibility check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Refund Eligibility Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth.

        summary: 'X402 Refund Amount Check: compares requested refund raw amount with original settled amount using only bounded caller-supplied values. Call when you need a bounded x402 refund amount check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Refund Amount Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'X402 Refund Deadline Check: checks a refund request timestamp against a policy window using only bounded caller-supplied values. Call when you need a bounded x402 refund deadline check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Refund Deadline Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'X402 Idempotency Check: compares payment and delivery idempotency keys for one operation using only bounded caller-supplied values. Call when you need a bounded x402 idempotency check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Idempotency Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'X402 Price Drift Check: compares advertised and challenged raw prices against a tolerance using only bounded caller-supplied values. Call when you need a bounded x402 price drift check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Price Drift Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'X402 Catalog Route Check: checks one catalog route for tool, method, path, and positive price using only bounded caller-supplied values. Call when you need a bounded x402 catalog route check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Catalog Route Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

Call when you need a bounded x402 registry route check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Registry Route Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth.

Call when you need a bounded x402 discovery parity check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for X402 Discovery Parity Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth.

        summary: 'Agent Result Envelope Check: checks a generic agent result for schema, status, and data or error using only bounded caller-supplied values. Call when you need a bounded agent result envelope check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for Agent Result Envelope Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Agent Result Provenance Check: checks result provenance for source, observed time, and method using only bounded caller-supplied values. Call when you need a bounded agent result provenance check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for Agent Result Provenance Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Agent Result Freshness Check: checks result observation age against a caller freshness budget using only bounded caller-supplied values. Call when you need a bounded agent result freshness check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for Agent Result Freshness Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Agent Result Completeness Check: checks required output paths for non-null values using only bounded caller-supplied values. Call when you need a bounded agent result completeness check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for Agent Result Completeness Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

Call when you need a bounded agent result cost check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for Agent Result Cost Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Agent Result Budget Check: checks cumulative caller-supplied spend against daily and per-call budgets using only bounded caller-supplied values. Call when you need a bounded agent result budget check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for Agent Result Budget Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Agent Delivery Sla Check: checks latency, success, and result completeness against an SLA using only bounded caller-supplied values. Call when you need a bounded agent delivery sla check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for Agent Delivery Sla Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Agent Delivery Fallback Gate: checks whether failure conditions permit a declared fallback using only bounded caller-supplied values. Call when you need a bounded agent delivery fallback gate result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for Agent Delivery Fallback Gate as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Agent Delivery Partial Result Check: checks partial-result coverage against a minimum fraction using only bounded caller-supplied values. Call when you need a bounded agent delivery partial result check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for Agent Delivery Partial Result Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Agent Delivery Order Check: checks delivered identifiers against expected order using only bounded caller-supplied values. Call when you need a bounded agent delivery order check result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for Agent Delivery Order Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Agent Delivery Dedupe Key: derives a stable non-secret key from operation and caller item identity using only bounded caller-supplied values. Call when you need a bounded agent delivery dedupe key result before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for Agent Delivery Dedupe Key as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Validates metadata only; it never settles payment, signs payloads, contacts a facilitator, refunds funds, or asserts on-chain truth. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: Allocate a total millisecond budget across ordered workflow steps using optional weights — call when you must split one wall-clock budget across ordered steps. Use before side effects when composing multi-step agent jobs—the same loyalty/workflow demand band agents already pay for on Bazaar, but fully local. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Build a bounded exponential retry delay schedule with a hard delay cap — call when configuring exponential backoff before calling a flaky dependency. Use before side effects when composing multi-step agent jobs—the same loyalty/workflow demand band agents already pay for on Bazaar, but fully local. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Create a stable SHA-256 idempotency fingerprint from a scope and canonical payload without storing state — call when writing a ledger or workflow event that must not double-apply. Use before side effects when composing multi-step agent jobs—the same loyalty/workflow demand band agents already pay for on Bazaar, but fully local. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Compute a stable topological order for workflow nodes and report structural cycles — call when ordering workflow nodes and detecting structural cycles. Use before side effects when composing multi-step agent jobs—the same loyalty/workflow demand band agents already pay for on Bazaar, but fully local. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Split a total timeout into per-step budgets after reserved overhead — call when carving a parent timeout into per-step slices after overhead. Use before side effects when composing multi-step agent jobs—the same loyalty/workflow demand band agents already pay for on Bazaar, but fully local. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Recommend a batch size from item count, hard cap, and average item bytes — call when batching micro-calls under item and byte caps. Use before side effects when composing multi-step agent jobs—the same loyalty/workflow demand band agents already pay for on Bazaar, but fully local. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Cap desired worker concurrency against a hard limit and queue depth signal — call when clamping desired parallelism against a hard worker limit. Use before side effects when composing multi-step agent jobs—the same loyalty/workflow demand band agents already pay for on Bazaar, but fully local. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base.

Results are advisory; the caller owns authorization, budgets, and production controls.'

Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Honest limit: execution uses only caller-supplied data in memory; it does not call a paid upstream, retain input, search the web, read a live RPC, or invoke a media generator. Results are advisory; the caller owns authorization, budgets, and production controls.'

        summary: Canonicalize and validate even-length hex strings with optional 0x prefix — call when normalizing even-length hex for chain tooling. Use for chain input hygiene without live RPC—adjacent to OneSource-class small chain reads, but static/local only so rights and margin stay clear. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Produce or validate an EIP-55 checksummed EVM address without network calls — call when producing or checking EIP-55 checksum addresses. Use for chain input hygiene without live RPC—adjacent to OneSource-class small chain reads, but static/local only so rights and margin stay clear. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Look up a static chain id to network name table without live RPC — call when mapping a static chain id to a network name (no tip). Use for chain input hygiene without live RPC—adjacent to OneSource-class small chain reads, but static/local only so rights and margin stay clear. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Extract the 4-byte function selector from calldata hex — call when reading the 4-byte selector from calldata. Use for chain input hygiene without live RPC—adjacent to OneSource-class small chain reads, but static/local only so rights and margin stay clear. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Validate Bitcoin-base58 alphabet membership for local address hygiene — call when checking Bitcoin-base58 alphabet membership locally. Use for chain input hygiene without live RPC—adjacent to OneSource-class small chain reads, but static/local only so rights and margin stay clear. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Check whether an address already matches its EIP-55 checksum form — call when verifying an address already matches EIP-55 form. Use for chain input hygiene without live RPC—adjacent to OneSource-class small chain reads, but static/local only so rights and margin stay clear. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Honest limit: execution uses only caller-supplied data in memory; it does not call a paid upstream, retain input, search the web, read a live RPC, or invoke a media generator. Results are advisory; the caller owns authorization, budgets, and production controls.'

        summary: Scale ether amounts into wei integer strings for transfers and tx value. Call when preparing value fields, allowances, or transfers denominated in ETH. Returns wei integer string and eth input as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

        summary: Convert percent values into basis points (1% = 100 bps). Call when bridging UI percent inputs into bps-based trading configs. Returns bps = pct*100 as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

        summary: 'EVM Nonce Gap Check: calculates the gap between pending and proposed transaction nonces using only bounded caller-supplied values. Call when you need a bounded evm nonce gap check result before signing, submitting, replacing, or accepting an EVM/Base transaction assembled from caller-owned data. Returns normalized transaction evidence, calculated budget or shape findings, and a fail-closed preflight status for EVM Nonce Gap Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses caller-supplied values only; it performs no RPC call, signing, broadcasting, balance lookup, custody, trading, or live-chain claim. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'EVM Batch Value Sum: sums bounded raw transaction values for a batch funding view using only bounded caller-supplied values. Call when you need a bounded evm batch value sum result before signing, submitting, replacing, or accepting an EVM/Base transaction assembled from caller-owned data. Returns normalized transaction evidence, calculated budget or shape findings, and a fail-closed preflight status for EVM Batch Value Sum as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses caller-supplied values only; it performs no RPC call, signing, broadcasting, balance lookup, custody, trading, or live-chain claim. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Base USDC Decimal Rounding: checks whether a decimal USDC amount fits six fractional digits exactly using only bounded caller-supplied values. Call when you need a bounded base usdc decimal rounding result before signing, submitting, replacing, or accepting an EVM/Base transaction assembled from caller-owned data. Returns normalized transaction evidence, calculated budget or shape findings, and a fail-closed preflight status for Base USDC Decimal Rounding as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses caller-supplied values only; it performs no RPC call, signing, broadcasting, balance lookup, custody, trading, or live-chain claim. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: Aggregate a bounded price list into open, high, low, and close — call when collapsing a price list into open/high/low/close. Use on caller-supplied ticks/returns when agents need signal prep without a licensed live market feed (ottoai-class demand, first-party transform). Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Compute mid price and bid-ask spread in basis points — call when computing mid and bid-ask spread in basis points. Use on caller-supplied ticks/returns when agents need signal prep without a licensed live market feed (ottoai-class demand, first-party transform). Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Estimate descriptive sample volatility from caller-supplied returns — call when estimating descriptive sample volatility from returns. Use on caller-supplied ticks/returns when agents need signal prep without a licensed live market feed (ottoai-class demand, first-party transform). Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Classify a signal against optional upper and lower thresholds — call when classifying a signal against upper/lower thresholds. Use on caller-supplied ticks/returns when agents need signal prep without a licensed live market feed (ottoai-class demand, first-party transform). Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Canonicalize a ticker symbol and split common base/quote separators — call when cleaning ticker symbols and splitting base/quote. Use on caller-supplied ticks/returns when agents need signal prep without a licensed live market feed (ottoai-class demand, first-party transform). Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Edge = true_prob − market_price for a binary contract. Call when ranking prediction-market opportunities by model edge. Returns signed edge in probability units as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

        summary: Overround/vig from a set of mutually exclusive implied probs. Call when measuring book margin before de-vigging. Returns overround and sum of probs as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

Returns normalized yes/no probs as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

        summary: Normalize multi-outcome prices into a probability simplex. Call when turning raw multi-outcome quotes into probs that sum to 1. Returns normalized probs and sum as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

        summary: Reliability diagram points (mean forecast vs hit rate per bin). Call when plotting calibration without a notebook stack. Returns bins with mean_forecast and hit_rate as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

        summary: Guess a MIME type from a filename, path, or URL extension — call when guessing MIME type from an extension. Use on text/URLs the agent already holds—adjacent to high-volume extract demand, never advertised as general web or X search. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Measure keyword density inside caller-supplied text — call when measuring keyword density in held text. Use on text/URLs the agent already holds—adjacent to high-volume extract demand, never advertised as general web or X search. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Detect dominant Unicode script families in a text sample — call when detecting dominant Unicode script families. Use on text/URLs the agent already holds—adjacent to high-volume extract demand, never advertised as general web or X search. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: Harvest URL and DOI citation patterns from text without network access — call when harvesting URL/DOI citation patterns without network. Use on text/URLs the agent already holds—adjacent to high-volume extract demand, never advertised as general web or X search. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

        summary: 'Combine success rate, latency score, and saturation into an ops health band — call when combining success, latency score, and saturation into a band. Use for SRE/ops math agents buy from broad utility catalogs: SLA, error budget, success rate, and health scores with zero upstream cost. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.'

        summary: 'Clamp an integer into an inclusive min/max range. Call when you need this bounded result before handing data to a downstream tool. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Honest limit: execution uses only caller-supplied data in memory; it does not call a paid upstream, retain input, search the web, read a live RPC, or invoke a media generator. Results are advisory; the caller owns authorization, budgets, and production controls.'

        summary: 'Seeded Shuffle: produces a reproducible permutation of caller items using only bounded caller-supplied values. Call when you need a bounded seeded shuffle result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Shuffle as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Partition: assigns each caller item reproducibly into a named partition using only bounded caller-supplied values. Call when you need a bounded seeded partition result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Partition as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody.

        summary: 'Seeded Train Test Split: splits items into reproducible train and test sets using only bounded caller-supplied values. Call when you need a bounded seeded train test split result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Train Test Split as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Kfold Split: assigns item indices to reproducible cross-validation folds using only bounded caller-supplied values. Call when you need a bounded seeded kfold split result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Kfold Split as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Bootstrap Sample: samples indices with replacement for a reproducible bootstrap set using only bounded caller-supplied values. Call when you need a bounded seeded bootstrap sample result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Bootstrap Sample as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Coin Flip: generates a reproducible sequence of binary outcomes using only bounded caller-supplied values. Call when you need a bounded seeded coin flip result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Coin Flip as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Random Float: returns reproducible floats inside caller bounds using only bounded caller-supplied values. Call when you need a bounded seeded random float result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Random Float as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded UUID: derives a reproducible UUID-shaped identifier from seed and namespace text using only bounded caller-supplied values. Call when you need a bounded seeded uuid result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded UUID as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Jitter Ms: adds reproducible bounded jitter to a base delay using only bounded caller-supplied values. Call when you need a bounded seeded jitter ms result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Jitter Ms as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Backoff Schedule: builds a reproducible jittered exponential backoff schedule using only bounded caller-supplied values. Call when you need a bounded seeded backoff schedule result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Backoff Schedule as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Round Robin Start: chooses a reproducible starting index for round-robin rotation using only bounded caller-supplied values. Call when you need a bounded seeded round robin start result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Round Robin Start as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Ab Assignment: assigns a stable subject to A or B using caller weights using only bounded caller-supplied values. Call when you need a bounded seeded ab assignment result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Ab Assignment as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Multivariate Assignment: assigns a stable subject to one weighted variant using only bounded caller-supplied values. Call when you need a bounded seeded multivariate assignment result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Multivariate Assignment as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Feature Bucket: maps a stable subject to an integer feature bucket using only bounded caller-supplied values. Call when you need a bounded seeded feature bucket result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Feature Bucket as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Consistent Shard: maps a stable key to one shard without mutable state using only bounded caller-supplied values. Call when you need a bounded seeded consistent shard result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Consistent Shard as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Rendezvous Rank: ranks nodes for a key using reproducible rendezvous hashing using only bounded caller-supplied values. Call when you need a bounded seeded rendezvous rank result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Rendezvous Rank as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Batch Order: orders batch identifiers reproducibly for replayable processing using only bounded caller-supplied values. Call when you need a bounded seeded batch order result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Batch Order as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Sample Indices: samples unique zero-based indices from a population size using only bounded caller-supplied values. Call when you need a bounded seeded sample indices result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Sample Indices as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Color Hex: selects a reproducible display color without claiming accessibility using only bounded caller-supplied values. Call when you need a bounded seeded color hex result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Color Hex as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Permutation Index: selects one reproducible permutation index within a caller count using only bounded caller-supplied values. Call when you need a bounded seeded permutation index result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Permutation Index as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody.

        summary: 'Seeded Weighted Partition: assigns items to partitions using reproducible capacity weights using only bounded caller-supplied values. Call when you need a bounded seeded weighted partition result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Weighted Partition as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Stratified Split: splits labeled items while preserving per-label proportions using only bounded caller-supplied values. Call when you need a bounded seeded stratified split result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Stratified Split as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Balanced Groups: distributes items reproducibly across near-equal groups using only bounded caller-supplied values. Call when you need a bounded seeded balanced groups result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Balanced Groups as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Derangement: finds a reproducible permutation where no item keeps its position using only bounded caller-supplied values. Call when you need a bounded seeded derangement result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Derangement as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Window Pick: selects a reproducible contiguous window from caller items using only bounded caller-supplied values. Call when you need a bounded seeded window pick result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Window Pick as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Time Slot Pick: selects a reproducible slot from caller-provided time labels using only bounded caller-supplied values. Call when you need a bounded seeded time slot pick result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Time Slot Pick as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: 'Seeded Canary Sequence: orders subjects reproducibly for a staged canary rollout using only bounded caller-supplied values. Call when you need a bounded seeded canary sequence result when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Canary Sequence as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses Python pseudorandomness for reproducibility, not cryptography, lotteries with value, security tokens, gambling, or custody. Advisory output only; the buyer owns authorization, payment policy, and production decisions.'

        summary: Bitcoin Up or Down 5-Minute Probability estimates p_up and p_down for rapid near-close windows where the freshest supplied observations matter most. Send 8-240 ordered caller-supplied BTC price observations, the target venue's opening price, and its close timestamp; optionally include UP/DOWN share prices and entry fees for a descriptive model-edge comparison. Returns a conservative probability pair, lean, input-quality score, model contract, and warnings for $0.003 USDC via x402 on Base or Solana. First-party, deterministic, memory-only execution with no input retention. It does not fetch exchange, oracle, or prediction-venue data; it never signs or places a trade. The probability is uncalibrated, venue resolution rules are not verified, and the output is not trading advice.

        summary: Bitcoin Up or Down 15-Minute Probability estimates p_up and p_down for quarter-hour windows using a broader caller-supplied trend sample. Send 8-240 ordered caller-supplied BTC price observations, the target venue's opening price, and its close timestamp; optionally include UP/DOWN share prices and entry fees for a descriptive model-edge comparison. Returns a conservative probability pair, lean, input-quality score, model contract, and warnings for $0.003 USDC via x402 on Base or Solana. First-party, deterministic, memory-only execution with no input retention. It does not fetch exchange, oracle, or prediction-venue data; it never signs or places a trade. The probability is uncalibrated, venue resolution rules are not verified, and the output is not trading advice.

        summary: Bitcoin Up or Down 30-Minute Probability estimates p_up and p_down for half-hour windows using the widest caller-supplied context in this family. Send 8-240 ordered caller-supplied BTC price observations, the target venue's opening price, and its close timestamp; optionally include UP/DOWN share prices and entry fees for a descriptive model-edge comparison. Returns a conservative probability pair, lean, input-quality score, model contract, and warnings for $0.003 USDC via x402 on Base or Solana. First-party, deterministic, memory-only execution with no input retention. It does not fetch exchange, oracle, or prediction-venue data; it never signs or places a trade. The probability is uncalibrated, venue resolution rules are not verified, and the output is not trading advice.

        summary: Ethereum Up or Down 5-Minute Probability estimates p_up and p_down for rapid near-close windows where the freshest supplied observations matter most. Send 8-240 ordered caller-supplied ETH price observations, the target venue's opening price, and its close timestamp; optionally include UP/DOWN share prices and entry fees for a descriptive model-edge comparison. Returns a conservative probability pair, lean, input-quality score, model contract, and warnings for $0.003 USDC via x402 on Base or Solana. First-party, deterministic, memory-only execution with no input retention. It does not fetch exchange, oracle, or prediction-venue data; it never signs or places a trade. The probability is uncalibrated, venue resolution rules are not verified, and the output is not trading advice.

        summary: Ethereum Up or Down 15-Minute Probability estimates p_up and p_down for quarter-hour windows using a broader caller-supplied trend sample. Send 8-240 ordered caller-supplied ETH price observations, the target venue's opening price, and its close timestamp; optionally include UP/DOWN share prices and entry fees for a descriptive model-edge comparison. Returns a conservative probability pair, lean, input-quality score, model contract, and warnings for $0.003 USDC via x402 on Base or Solana. First-party, deterministic, memory-only execution with no input retention. It does not fetch exchange, oracle, or prediction-venue data; it never signs or places a trade. The probability is uncalibrated, venue resolution rules are not verified, and the output is not trading advice.

        summary: Ethereum Up or Down 30-Minute Probability estimates p_up and p_down for half-hour windows using the widest caller-supplied context in this family. Send 8-240 ordered caller-supplied ETH price observations, the target venue's opening price, and its close timestamp; optionally include UP/DOWN share prices and entry fees for a descriptive model-edge comparison. Returns a conservative probability pair, lean, input-quality score, model contract, and warnings for $0.003 USDC via x402 on Base or Solana. First-party, deterministic, memory-only execution with no input retention. It does not fetch exchange, oracle, or prediction-venue data; it never signs or places a trade. The probability is uncalibrated, venue resolution rules are not verified, and the output is not trading advice.
