preflight_x402_endpoint — Preflight 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, signable accepts, testnet catch — with every check named and what a single probe cannot tell you.
lookup_endpoint_readiness — Read 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, the gaps counted against the observer.
get_defect_definition — The definition of one named x402 defect class from the store's registered vocabulary: what a clear door asserts, what a buyer loses when it is present, whether it is detectable without paying, which check reports it, and what observation would disprove it.
verify_scvd_artifact — Verify a certificate, stamp or anchor id this store issued: the exact signed bytes and the ed25519 key, so the check can be repeated offline.
