6 services carry this tag in their source record. Tags come from the provider, not from us — a tag is a claim about what the service does, not proof that it does it well.
Pay-per-KYA: an agent pays to verify another agent's post-quantum identity + scope credential (Dilithium-2, NIST FIPS 204), with a live FRC-55 on-chain reputation read. ERC-8004-aligned Know Your Agent for autonomous age...
Pay-per-KYA-credential: a post-quantum-signed agent identity + scope credential — a Dilithium-3 (NIST FIPS 204) credential PLUS an additive ML-DSA-65 / Dilithium-3 (NIST FIPS 204) served signature over the same canonical...
Counterparty trust verification for agents: before transacting with a domain, verify its trust artifacts — DNSSEC + DNS-AID records, agent-card, live MCP endpoint, published JWKS, OASF record, x402/commerce declarations....
Signed verdict: is this action (action, amount, currency, counterparty, payment instrument) inside the agent's mandate and is the credential active? Evaluates the reserved mandate fields; lists the fields it did not eval...
Silicon DNA agent identity classification. Behavioral timing analysis: CPU jitter entropy (L0), Shannon entropy (L2), Spearman rank correlation (L3) to classify as HUMAN, LEGIT_AGENT, MALICIOUS_BOT, SYBIL, or UNKNOWN (no...
Same lookup as /lookup/{agentId} — this route exists to measure willingness-to-pay and x402 Bazaar discoverability, not because the result is different or better paid.
