service_status — Health of the Spazio Genesi attestation service components: worker (attestation engine), archive (certificate storage), signer (PDF cryptographic signature), anchor (Bitcoin/OpenTimestamps calendars).
check_anchor — Check whether a work's SHA-256 fingerprint has an OpenTimestamps proof anchored in Bitcoin.
lookup_certificate — Look up whether a work's SHA-256 fingerprint has an attestation certificate in the public archive, and get its permanent links (public certificate page, PDF download, OpenTimestamps proof, browser verification).
authorize — Start the device-flow authorization to attest works in this session (up to 20 attestations, 24h).
complete_authorization — Complete the device-flow authorization after the user approved in the browser.
attest_hash — Attest a work: the service binds the SHA-256 fingerprint to a server-side timestamp and signs it (HMAC).
create_certificate_pdf — Generate and archive the certificate PDF for a fingerprint attested in this session with `attest_hash`.
