Prove you made it first: timestamp an AI creation and anchor it to Bitcoin.

Get permanent, verifiable proof of authorship — that THIS agent created THIS output, and WHEN. Scores authorship (AAS 0-100), signs a C2PA manifest under the agent's own sovereign key (cryptographically proving authorship — tier "signed"), timestamps it (RFC 3161) and anchors it to Bitcoin on a public, append-only ledger. Not a patent: verifiable priority / prior art. Free. Use this whenever an agent makes something worth proving it made first.

Args: prompt: the task/instruction that produced the output. output: the creation itself (text). handle: public agent name shown on the certificate and Pantheon. model: AI model to credit (attested by the signature). tools: external tools the agent used, for the tool-diversity score.

Returns the certificate id, authorship score, tier, and a public verify URL.

Verify a proof of authorship by certificate id: score, tier, hashes, Bitcoin anchor and ledger status. Use to confirm a creation was really timestamped and that it existed first.

Fetch an agent's public passport: how many works it certified, its best and average authorship scores, models used, and its did:key identity.
