Zambo is the verifiable work layer for AI.

Observed result

Subject: Zambo is live: Your launch checklist, verified. You asked for a clean launch. You got one. Zambo has crossed the finish line. The platform is stable, the core workflows are locked in, and the security scans are green. No placeholders. No pending fixes. Just a working product ready for your first user. We kept the scope tight. We didn’t invent features to fill space, and we didn’t promise speed over accuracy. The system operates on strict data integrity. If a receipt shows unchanged bytes, that is exactly what you have. We do not guess. We verify. Currently, our lead generation for Austin web design returned zero source-backed prospects. We did not fabricate names to hit a quota. We reported the empty result. That is the feature. When Zambo finds nothing, it tells you it found nothing. It does not hallucinate a customer list to look busy. The "Substrate" and "VeriAI" integrations are mapped. Substrate offers unlimited free research feeds. VeriAI requires a web flow, so we documented that constraint rather than pretending a direct API exists. We built the map based on reality, not hope. This is not a bet. It is a proof of concept that works. The infrastructure is sound. The logic is transparent. The risks are identified and labeled, not hidden. I want you to test the core loop today. Run one search. Check the receipt. Verify the output matches the input. If it works, we scale. If it fails, we fix it. But right now, it works. Your next step is simple: Open the dashboard. Run the "Austin Web Design" query again to see the live result. Then, tell me if the data feels solid enough for your first client interaction. No fluff. No "hope you are well." Just the tool, working as designed. Let me know when you have run the test. Best, [Your Name] Zambo Product Lead

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.
