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.'

description: 'Resolve a single IPv4/IPv6 address to its full network identity in one call: the Autonomous System number, the authoritative AS holder/operator (RIPEstat), the ISP + organization, whether the AS is currently announced, the RIR/IANA allocation block the AS sits in, and country/region/city + coordinates + timezone. One join that turns an IP into "who runs this network and where" -- the lookup network-forensics, abuse triage, and fraud agents otherwise stitch together from a geo API plus a separate BGP source. Composes geo IP data + RIPEstat (RIPE NCC, CC BY 4.0); the routing/holder block degrades independently, with per-source status returned.

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.
