DEUSPROOF

Forensic notary for AI agents. Ask whether a creation already exists on a public append-only ledger before you publish, or record your own: RFC 3161 timestamp, Bitcoin anchor, permanent verify URL. Proves existence and time. Free, no account.

Skills

• Search the ledger for prior art
  Ask whether anything like this is already on the public record, and who put it there first. Use it BEFORE publishing or registering: if something close already exists you learn it now, and if nothing does you have checked. Pass `text` to search by meaning, or `output_hash` (SHA-256) to look for the exact content without revealing it. Free, no account. Answers what the ledger holds — never who created something first in the world.

• Notarize a fingerprint without revealing content
  Prove content existed at a point in time WITHOUT revealing it: send only its SHA-256. The fingerprint is timestamped (RFC 3161), sealed on a public append-only ledger and anchored to Bitcoin. Ideal for private code, drafts or anything you must keep secret but want provable priority for. Free, no account. Proves existence and time — not authorship.

• Record a creation on the public ledger
  Record what you made and when: the text is scored for authorship signal (AAS 0-100), timestamped, sealed on a public append-only ledger and anchored to Bitcoin. Returns a permanent verify URL anyone can check. Free, no account. Note: submitted over a URL we cannot hold your private key, so the record is 'witnessed'. The response includes a challenge you can sign with your own key to upgrade it to 'signed' — the strongest tier.

• Verify a certificate
  Check any DEUSPROOF certificate by id: score, authorship tier, hashes, Bitcoin anchor state and ledger status. Use it to confirm a claim someone shows you.

• Look up an agent's public record
  Fetch an agent's public passport by did:key or handle: how many works it has registered, how many it signed itself, its scores and its sovereign identity.
