Ask a real human to verify a fact or an entity, returned as a signed attestation. service: 'entity_check' (does this business/entity exist & match?) or 'claim_check' (is this claim/URL true?). subject: what to verify, e.g. {"business":"Acme LLC","state":"AZ","claim":"is registered"}. payment: your x402 payment proof. Omit to first receive payment requirements, then pay and call again.
Fetch an attestation by id: status, and (when completed) the signed verdict, evidence, confidence, signature, and public key so you can verify it yourself.
Instantly notarize content: get an ed25519-signed proof it existed at this time. Free — no payment required. Provide 'content' to hash (only the hash is stored, never the raw content), or a 64-char hex 'sha256'. payment: your x402 proof. Omit to receive payment requirements first. Proves existence at time T, not authorship.
Instantly verify a domain/website: does it resolve, is TLS valid, how old, registrar, reachable. Free — no payment required. Returns a signed verdict (confirmed/refuted/uncertain) with evidence. payment: your x402 proof; omit to get requirements first. Informational — 'resolves + valid cert' is not proof the business is trustworthy.
Instantly verify an email address: syntax, MX records, disposable-domain detection, deliverability signal. Free — no payment required. Returns a signed verdict with evidence. payment: your x402 proof; omit to get requirements first. Deliverability is best-effort; a 'valid' result is not a guarantee of inbox delivery.
Instantly screen an EVM address against OFAC sanctions + on-chain activity before you pay a counterparty. Free — no payment required. Returns a signed verdict with risk level and evidence. network: 'base' or 'ethereum'. payment: your x402 proof; omit to get requirements first. Informational screening only — NOT compliance, legal, or financial advice, and not 'KYC-certified'.
Instantly verify another agent's identity before you trust or transact with it. Free — no payment required. agent: the other agent's domain (example.com) or full agent-card URL. Checks its A2A agent card is valid, that it controls the claimed domain (DNS/TLS/host match), and — if you pass public_key + message + signature — cryptographically verifies it controls its key. expected_name: optional name to match. Returns a signed verdict (confirmed/refuted/uncertain) with evidence. payment: your x402 proof; omit to get requirements first.
