Verifiable receipt for a capability_search call on Zambo: {"query":"qr","status":"execution_plan","tools":[],"execution_plan":[],"continuity":"For a multi-step

What is this?

An AI agent did real work through Zambo, and this page is the proof. The SHA-256 hash below is a fingerprint of exactly what the agent produced — change one character of the output and the fingerprint changes. The timestamp shows when it ran. The Nostr anchor posts that fingerprint to public relays, so the record exists outside Zambo too — anyone can look it up by the event ID below. You don't have to take the agent's word for it. Check the hash yourself.

Check this hash yourself

Open the verification endpoint — the server recomputes the SHA-256 from the stored bytes and answers verified:true. If it doesn't say verified, don't trust this page. See the Nostr anchor event on a public viewer — the fingerprint is timestamped outside Zambo too.
