  The public OpenAPI declares no component schemas (paid bodies are typed additionalProperties: true), so
  the graph is derived from path parameters and the documented response examples at
  https://onchainagentintel.io/docs (public agent summary, paid profile, subscription, subscription status),
  the /agent.json services[] pathSchema/querySchema/requestSchema fields, and the live /v1/public/stats and
  402 bodies observed 2026-09-19. Field names are the provider's; cardinalities are inferred from them.

notation: relationships use has_one / has_many / belongs_to with the referencing field name; direction is from the entity that owns the reference.
entities:
- name: Agent
  key: '(chain, agent_id)'
  domain: registry
  description: >-
    An ERC-8004 registered agent (IdentityRegistry row) on Base or Ethereum; the unit every intel operation is about.
- name: Chain
  key: 'chain'
  domain: registry
  description: >-
    base | ethereum — the settlement and registry network; /v1/public/chain/{chain} rolls agents up by it.
- name: Capability
  key: 'slug'
  domain: registry
  description: >-
    A capability tag agents advertise; /v1/public/capability/{slug} lists agents matching it; /v1/intel/market analyses saturation per capability.
- name: ObjectiveSignals
  domain: measurement
  description: >-
    Per-agent observed booleans/counts (reachable, http_status, tls_valid, x402_supported, payments_received, mcp_tool_count, openapi_method_count, has_well_known, owner_named, owner_is_contract, owner_contract_verified, last_indexed_at, last_active_check).
- name: ReadinessScore
  domain: measurement
  description: >-
    Buyer-POV Agent Readiness & Trust composite 0-100 with bucket (Transact-ready | Promising | Not ready | Unrated) and subscores live / payable / reputable / active; status_label on the free summary.
- name: Owner
  domain: identity
  description: >-
    Resolved owner identity (ENS / Basename / Farcaster) and explorer label; paid field, exposed as owner_named boolean on the free summary.
- name: PaymentActivity
  domain: on-chain
  description: >-
    ETH + USDC received, tx counts; edges of the agent-to-agent payment graph (/v1/intel/graph, free teaser via MCP get_network_teaser).
- name: CoverageStats
  domain: measurement
  description: >-
    Ecosystem totals from /v1/public/stats (agents_indexed, live_agents_total, mcp_agents, openapi_agents, well_known_agents, readiness_buckets, per-chain breakdowns, generated_at).
- name: Dataset
  key: 'slug'
  domain: publishing
  description: >-
    Citable CC BY 4.0 dataset descriptor from /v1/public/datasets/{slug}; catalogued as schema.org DataCatalog at /data.json.
- name: PaymentChallenge
  key: 'intel_id | sub_id | audit id | eval id'
  domain: commerce
  description: >-
    The 402 body a paid operation returns — x402Version, accepts[], payment_options[], preview, expires_at (offer window).
- name: PaymentOption
  domain: commerce
  description: >-
    One accepts[]/payment_options[] entry — network, chain_id, token/asset, amount, payTo, payment_method (EIP-3009) or calldata prefix.
- name: Subscription
  key: 'sub_id'
  domain: commerce
  description: >-
    30-day flat-rate entitlement — subscriber_addr, status PENDING | ACTIVE | EXPIRED, created_at, paid_at, expires_at, payment_tx, payment_chain; covers seven intel endpoints.
- name: AuditReport
  domain: security
  description: >-
    Output of POST /v1/audit — risk level, per-finding remediation across 16 vulnerability classes.
- name: Evaluation
  domain: security
  description: >-
    Output of POST /v1/evaluate — ERC-8183 evaluator attestation; complete() or reject() called on the client job contract with the report hash.
