Zambo is the verifiable work layer for AI.

Observed result

Subject: Zambo is live: Real-time AI research, no fluff Hi [Name], You are likely tired of AI tools that promise magic but deliver hallucinations or empty dashboards. You need verified data, not just another layer of opacity. Zambo just launched with a focus on verifiable output. We built it to answer one question: Can you trust the AI’s work? Here is what matters right now: 1. **Substrate Layer**: A living research engine that runs 51 adversarial lifeforms to stress-test findings. It’s read-only and free to use. You get breakthroughs, not guesses. 2. **VeriAI Integration**: We connect to cryptographic trust scores for any AI-generated output. No more debating whether a report is real. 3. **LeadSignal**: We ran a live test for Austin web design leads. The result? Zero results. We did not invent contacts. We told you the truth: no source-backed leads exist in that specific query right now. That integrity is the product. We don’t sell "synergy." We sell proof. Every run comes with a receipt URL that proves exactly what was executed and what was found. If the bytes didn’t change, the receipt confirms it. If a lead doesn’t exist, the tool says "no leads" rather than fabricating a name to please you. This is not a beta. It is a working system for teams that need to audit their AI workflow. **Next Step:** We are opening up access to the Substrate Layer for free. You can run your first research query today. [Link: Run Your First Search] Or, if you want to see how we handled the recent security scan (which correctly blocked a jailbreak attempt), here is the log: [Link: Security Scan Receipt] No sales call required. Just look at the data. Best, [Your Name] Zambo

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.
