Pre-settlement merchant screen: signed ALLOW/WARN/BLOCK on a (domain, payTo, observed price) BEFORE an agent settles an x402 payment. ms-v1 ruleset over first-party signals measured at query time — RDAP domain age, live TLS handshake (cert age, issuer, SAN match), off-domain redirect probe, brand-similarity distance vs a committed known-brand corpus, and the merchant's own advertised x402 manifest price. Method disclosed per field; unmeasurable signals report unverified and only lower confidence. The verdict carries an embedded EIP-712 PayloadAttestation — recompute keccak256(answer) and recover the signer before acting. Trust boundary: the payTo and price are values you assert, not values we observe on your payment — the verdict is a point-in-time snapshot of the exact tuple you supplied, and it neither sees nor constrains the address you ultimately settle to. Before releasing funds compare answer.query against the 402 challenge you are about to pay (answer.query.address is lowercased — compare case-insensitively). The receipt proves provenance and integrity, not correctness. Every query is logged and retained: the domain, the payTo address and price you supplied, the verdict, and a summary of the signals behind it. Producing a verdict requires live outbound requests against the screened domain itself — the merchant may observe this traffic; screening is not covert.","tags":["commerce","x402","usdc","base"],"inputModes":null,"outputModes":null}],"skills_removed":[{"id":"evidence-pack","name":"Evidence Pack Oracle","description":"RAG-citable meta-oracle: retrieve from PayPerByte factual feeds + signed citation bundle with sources.","tags":["general","x402","usdc","base"],"inputModes":null,"outputModes":null},{"id":"liquidation-stream","name":"Liquidation Stream Oracle","description":"Hawkes branching-ratio (self-excitation) verdict over a first-party realized-liquidation archive: SUBCRITICAL/NEAR_CRITICAL/SUPERCRITICAL.","tags":["financial","x402","usdc","base"],"inputModes":null,"outputModes":null}],"skills_changed":[{"id":"address-reputation","fields":["description"]},{"id":"sanctions-screen","fields":["description"]}],"fields_changed":[],"other_changed":true,"is_empty":false,"human_summary":"added 1 skill · removed 2 skills · updated 2 skills"}},{"captured_at":"2026-07-07T04:37:42","card_hash":"0ab91ae45a25babb2e5fcd7535d9e28fd2b8278045480df8de11be8f3686d263","previous_card_hash":null,"diff":{"skills_added":[{"id":"address-reputation","name":"Address Reputation Oracle","description":"Agentic-payments go/no-go verdict: synchronous signed ALLOW/WARN/BLOCK for (domain, receiving address, amount, chain) BEFORE releasing USDC. ar-v1 ruleset over RDAP/TLS/DNS/Wayback domain signals + on-chain receiving-address signals + curated known-bad blocklist.
