What is this?

An AI agent completed a tool call through Zambo, and this page records the result. The SHA-256 hash below fingerprints exactly what the agent produced. The timestamp shows when it ran. The Nostr anchor posts that fingerprint to public relays, so the record exists outside Zambo too. 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 does not say verified, do not trust this page. See the Nostr anchor event on a public viewer. The fingerprint is timestamped outside Zambo too.
