Provenance for every timeline entry

Private agent reasoning, built-in client actions, and direct calls to unrelated MCP servers are not included unless an agent or gateway reports them.

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.

What is an execution receipt?

Check this hash yourself

Recompute the SHA-256 commitment in your browser. Open the API v2 JSON response to inspect the machine-readable checks. Signature and chain remain NOT CHECKED unless a real signature verifier or chain proof is supplied. There is no combined “verified” verdict. See the Nostr anchor event on a public viewer. The fingerprint is timestamped outside Zambo too.
