8 tools

• service_status

  Health of the Spazio Genesi attestation service components: worker (attestation engine), archive (certificate storage), signer (PDF cryptographic signature), anchor (Bitcoin/OpenTimestamps calendars). Values: ok | degraded | down | n/d.

• check_anchor

  Check whether a work's SHA-256 fingerprint has an OpenTimestamps proof anchored in Bitcoin. The proof is created at attestation time and matures (pending → Bitcoin-confirmed) within a few hours.

• verify_attestation

  Verify the server HMAC signature of an attestation issued by the Spazio Genesi service. Confirms that the attestation string (fingerprint + timestamp) and any declared metadata are authentic and untampered. Note: this checks the SIGNATURE only. Whether a given file matches the…

• 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). Trust model: this information is reachable only by whoever knows…

• authorize

  Start the device-flow authorization to attest works in this session (up to 20 attestations, 24h). Returns a link the USER must open in a browser and approve (anti-bot check included). After the user approves, call `complete_authorization`. Not needed if the connection already…

• complete_authorization

  Complete the device-flow authorization after the user approved in the browser. Polls the service briefly; if approval hasn't happened yet, just call this tool again.

• attest_hash

  Attest a work: the service binds the SHA-256 fingerprint to a server-side timestamp and signs it (HMAC). Requires a credential (device flow via `authorize`, or an API key header). Optional declared metadata (title/author/year/notes) are normalized and BOUND by the signature…

• create_certificate_pdf

  Generate and archive the certificate PDF for a fingerprint attested in this session with `attest_hash`. The PDF is cryptographically signed, anchored in Bitcoin (OpenTimestamps) and archived server-side; this tool returns the permanent links (the PDF itself is downloadable from…
