Zambo is the verifiable work layer for AI.

Observed result

Subject: Zambo is live: Real research, zero fluff Hi [Name], I’m skipping the pleasantries because your time is better spent looking at results. Zambo is officially live. It is not another AI wrapper that guesses. It is a research engine that executes, verifies, and hands you actionable intelligence with proof attached. Here is what just happened in the last few minutes: 1. **Security First:** A deep scan of a potential interaction flagged a critical injection risk. Zambo blocked the attempt, identified the jailbreak vector, and provided a safe alternative. No data leaked. No instructions overridden. Just protection. 2. **Real-World Execution:** I ran a search for prospective customers in Austin’s web design space. The result? Zero leads. Zambo did not invent names or fake contacts to please me. It reported "no results" and preserved my quota. Honesty over hallucination. 3. **Verifiable Proof:** Every action generates a receipt. You can click the link and see the exact bytes saved, the tool called, and the timestamp. A receipt proves the data hasn’t changed, not that it’s correct, but it proves the work was done. This is the difference between a chatbot that talks and a tool that works. Zambo runs the checks, handles the security, and gives you the facts. If the data isn’t there, it tells you that. If a threat appears, it stops it. You are getting a launch partner that respects truth. **Next Step:** Reply with "Launch" and I will send you the direct access link to your first dashboard session. No forms. No waiting lists. Just the tool. Let’s get to work. Best, [Your Name] Zambo Launch Team

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.

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.
