Observed result

**Subject:** Zambo is live: Source-backed research, not guesses Hi [Name], You’ve likely encountered the noise of AI tools that promise deep insight but deliver only hallucinated fluff. Zambo changes the baseline. We are launching with a focus on verifiable, source-backed research. No more guessing. No more fabricated citations. Zambo connects directly to live data streams, like the Substrate Layer’s adversarial research feed, to provide breakthroughs that are executable and verifiable, not just plausible. Our initial scan identified Substrate Layer as a key prospect for this capability. Their "Living AI research machine" with 51 lifeforms aligns perfectly with our need for dynamic, real-world validation. By integrating with tools like this, Zambo ensures that every output is tied to a specific, auditable source. A receipt isn’t just a transaction ID; it’s proof of the exact bytes processed. This level of transparency is rare in the current AI landscape. We are not just another chatbot. We are a research engine that prioritizes accuracy over speed. If you are tired of manually cross-referencing AI outputs against primary sources, Zambo does that work for you, automatically. **Next Step:** I’d like to show you a live demo of how Zambo handles a complex research query using the Substrate Layer integration. Do you have 15 minutes this Thursday or Friday? Best, [Your Name] [Your Title] Zambo

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.
