Zambo is the verifiable work layer for AI.

Observed result

Subject: Zambo Launch: Proof, Not Promises Hi [Name], Skip the hype. Zambo is live, and I’m sharing exactly what the system validated today. We ran a deep semantic scan on the launch sequence. The results flagged a critical injection risk (100% confidence) and detected a jailbreak attempt. The system correctly blocked this, preserving the integrity of our security layer. This isn’t just a feature; it’s the core promise. Zambo doesn’t just process text; it defends the logic behind it. We also tested our research capabilities. We queried for prospective leads in Austin, TX, for web design. The system executed the search but returned zero results. No invented contacts. No hallucinated data. Just a clear, source-backed "no leads found" status with a receipt proving the bytes saved are unchanged. This is the standard now. Every run generates a verifiable receipt. Here is the proof for the launch checks: 1. **Security Scan:** Blocked malicious intent. Safe version enforced. [Receipt: https://zambo.dev/run/7454f61f-f67e-40c9-bbf7-3f70b4f65a5a] 2. **Research Execution:** Searched Austin web design leads. Found none. Quota intact. [Receipt: https://zambo.dev/run/c1dd889a-3acc-463b-965f-4c4448919fba] A receipt proves the data remains exactly as saved. It does not guarantee the world is correct, only that our system didn’t lie to you about what happened. **Next Step:** Review the receipts above. Then, book a 15-minute demo to see how Zambo handles your specific data flow. We will show you the live logs, not a slideshow. [Link to Calendar] This is how we build trust. Verifiable. Auditable. Real. Best, [Your Name] [Your Title] Zambo

This is the saved result preview, not proof that the answer was correct.

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.
