Tools 5
scvd_x402_verifier_get_defect_definitionRead one named x402 defect class from the store's registered vocabulary. What a clear door asserts, what a buyer loses when the defect is present, whether it is detectable without paying. Leave the id empty to list every class.scvd_x402_verifier_lookup_endpoint_readinessLook up what the signed weekly x402 readiness corpus holds about one host. Rounds probed of rounds since first sighting, the last signed verdict, the tier with its fraction, and the gaps counted against the store. Never a ranking.scvd_x402_verifier_preflight_x402_endpointPreflight an x402 endpoint before paying it. One unpaid probe answering whether the URL serves a well-formed x402 v2 challenge a stock client could sign: 402 status, parseable PAYMENT-REQUIRED header, offer terms present. Every check is named, and so is anything the probe could not tell.scvd_x402_verifier_verify_scvd_artifactVerify a certificate, stamp or anchor id this store issued. Returns the exact signed bytes and the ed25519 key, so the check can be repeated offline. Free forever, whether or not anyone bought the thing.scvd_x402_verifier_verify_x402_receiptVerify an x402 signed receipt or offer from any issuer. Structure, signature against the issuer's key, liveness. Pass the public key for a fully offline check; otherwise the issuer's did:web key is resolved.
