Show technical provenance details

Provenance for every timeline entry

  • EXECUTED BY ZAMBOZambo ran the tool call itself.
  • OBSERVED VIA GATEWAYA Zambo gateway observed request and response bytes from the named external executor. Zambo did not run that external action.
  • LOGGED BY AGENTAn agent or local hook reported the action. Zambo attests that the record is unchanged since logging, not that the action happened as described.

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 an execution receipt?

An execution receipt is a public record of a reported AI agent tool call. Its byte commitment and provenance claim can be checked independently; neither alone authenticates the issuer. Read the canonical definition of an AI agent execution receipt.

What the receipt can and cannot prove

What is this?

Zambo's receipt store reports a tool call and records its result. The SHA-256 commitment covers the exact canonical bytes. The provenance label is bound to v0.4 receipt bytes when that check passes, but no pinned signature or trusted issuer key is checked. An anchor can timestamp a fingerprint; it does not authenticate the issuer.

This receipt records a completed tool call. When the free allowance is not enough, choose the access path that fits the job.

Anchor status "published": Published to all configured relay targets.

Relay publication is separate from receipt integrity. When the original signed event is available, Zambo retries pending, partial, or failed anchors about once a minute. Relay acknowledgements are external, so there is no guaranteed completion time; the receipt remains checkable from its saved bytes and verification link.

Check this hash yourself

Receipt commitment: commitment matched; issuer, signature and chain not checked. This checks the saved bytes, not whether the answer was correct. Recompute the SHA-256 commitment in your browser. Open the API v2 JSON response to inspect the machine-readable checks. See the Nostr anchor event on a public viewer. The fingerprint is timestamped outside Zambo too.
