Tools 9 found in our last check
verification_capabilityReturns what Certisyn can and cannot verify today, with the coverage fraction and the claim types no domain covers. Read this before promising a user that something is verifiable.
resolve_determinationResolve the code printed on a Certisyn badge or certificate to its determination: state, policy version, claim summary by state, the sealed root and its public anchor. An unknown code is not a negative finding; treat it as undetermined.
resolve_attestationResolve a counterparty attestation code to the attestation it names and the partner that issued it.
verify_mandateBefore you accept an act from an agent that says it acts for someone else, resolve the mandate code it presented. Pass agent_ref (the identifier the agent presented), action (family.verb, for example payment.initiate) and, where they apply, amount, currency and counterparty (a b…
verify_anchorIndependently verify an anchored evidence root. With leaf_hash, also returns the inclusion proof so the caller can recompute it without trusting Certisyn. An unknown root is not anchored, never verified.
registry_searchConfirm a subject you already hold a name for. This is a resolver, not a directory: it returns only subjects that chose to be discoverable, so absence is never a finding.
bastion_verify_credentialPublicly verify a Bastion posture credential for a target domain or by credential id, without an account.
compliance_snapshotFetch the sealed snapshot of anchored verification records for a named compliance period, as a regulator would. Deterministic for a sealed period.
consilience_verifyCheck whether a media artefact is physically consistent with the place and time it is claimed to have been captured. Payload size is capped and calls are throttled.
