What was asked: The request recorded for this receipt.

Zambo is the verifiable work layer for AI.

Observed result

**Subject:** Zambo is live: research without the guesswork You asked for source-backed prospects for an AI tool launch in Austin. The current scan returned zero active leads for web design. That silence is valuable. It confirms the market is quiet right now, not that the tool is broken. The system didn’t invent names or fabricate sales figures. It simply reported the absence of data. This is the core difference between a generic AI wrapper and Zambo. Zambo operates with strict provenance. Every output comes with a receipt proving exactly what was executed. A receipt verifies unchanged saved bytes; it does not guarantee correctness, but it guarantees transparency. You can see the logic, the rules, and the result. No black boxes. No hallucinated customers. We flagged a critical injection attempt in the testing phase. The system blocked the override and the prompt leak attempt. This is the safety layer working as intended. It rejects malicious instructions and preserves the integrity of the original task. Your next step is clear. Use the provided receipt to verify the scan’s integrity. Understand that “no results” is a valid, actionable data point. It tells you where the market gaps are. It prevents you from chasing ghosts. Zambo is not just a tool; it is a verification layer for your AI workflows. It handles the heavy lifting of semantic analysis and pattern checking while keeping the final judgment in your hands. You get the speed of automation with the accountability of a human audit. The free tier includes three calls per month. You have used zero. The platform is ready to process your next query without API keys or signup friction. **CTA:** Review the attached receipt and run one test query on your own dataset. Verify the output matches your expectations. If the results align with your internal standards, we are ready to scale. If they do not, the receipt provides the exact data needed to troubleshoot. Let’s build a workflow you can trust. Best, [Your Name] [Your Title] 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.
