  x-guidance: 'Pay-per-call REST API for AI agents — hundreds of endpoints returning ground-truth data (US public records, company & legal identifiers, finance/SEC, crypto/web3, security & CVEs, medical codes, weather & geocoding, agriculture, energy, maritime, music, and more). Every endpoint is paid per call in USDC via x402 (Base or Solana) — no API key, no signup. Call any endpoint with no auth to get a 402 PaymentRequirements envelope, sign it (EIP-3009 on Base, partial SPL transfer on Solana), and retry with the PAYMENT-SIGNATURE header. Add ?trial=1 for one free real call per endpoint per hour to test before paying. To discover the right endpoint: GET https://2s.io/api/directory for the full catalog, or GET https://2s.io/api/search/endpoints?q=<natural-language task> for a ranked match. Per-call price is on each operation as x-payment-info (from $0.001). Batch up to 50 calls behind one payment via POST https://2s.io/api/batch/run.'

      summary: Look up an Autonomous System (BGP) by AS number
      description: 'Look up an Autonomous System (BGP) by AS number. Pass asn as AS3333 or 3333. Returns the AS holder/operator name, the IANA/RIR allocation block it falls in, whether it is currently announced, and a live routing-status block: first/last seen prefixes, announced IPv4/IPv6 prefix + address counts, RIS peer visibility, and observed BGP neighbour count. Data: RIPEstat (RIPE NCC), free and public. Distinct from geo.ip (host geolocation) and dns/whois (name lookups) — this is who-owns-and-routes-this-AS, observed live from the global routing table. For network forensics, abuse/security triage, and infrastructure mapping.'

Accepts any common format — FC:FB:FB:01:02:03, fc-fb-fb-01-02-03, fcfb.fb01.0203, fcfbfb, or a 9-hex MA-S prefix. Uses longest-prefix matching across the IEEE MA-L (24-bit), MA-M (28-bit) and MA-S (36-bit) registries so blocks IEEE has subdivided resolve to the actual manufacturer. Returns the vendor name, the matched OUI prefix and which registry it came from, plus decoded address bits: whether the address is multicast/group, locally administered, or a randomized (privacy) MAC — for which no vendor exists by design.

      summary: RPKI Route Origin Validation for a (BGP origin AS, prefix)
      description: RPKI Route Origin Validation for a (BGP origin AS, prefix) pair — answers whether an AS is legitimately authorized to originate a prefix. Pass asn (e.g. AS15169) and prefix (CIDR, e.g. 8.8.8.0/24). Returns status (valid = a ROA authorizes it; invalid = a ROA exists but does NOT authorize this origin — a possible hijack/route-leak that RPKI-enforcing networks will drop; unknown = no covering ROA), a hijackSignal boolean, the validating ROAs (origin, prefix, maxLength), and a plain-English description. Live RIR/RPKI data via RIPEstat (keyless) — un-derivable by an LLM. The core BGP-security check; complements net.asn.
