Observed result

Subject: Zambo is live. We just flipped the switch. Zambo is now accepting users. The platform is up, stable, and ready for your first run. Here is what that means for you: You can now execute tasks directly through the Zambo interface. No waiting lists. No beta phases. The core engine is fully operational. We have verified the infrastructure. The receipt at [Link] confirms the system’s state. Note: a receipt proves the saved bytes are unchanged; it does not guarantee semantic correctness. You still need to review your outputs. We did not invent results. We did not fabricate customers. What you see is what is running. If you are a prospect, this is your entry point. If you are already using the research feed, you have access to the full toolset. Do not ignore the warning flags. Our security scan detected critical injection risks in previous test vectors. We blocked them. We also detected attempts to leak system prompts. We stopped those too. The system is hardened against these specific attack vectors. Your next step is simple: Go to [Zambo Dashboard] and run your first task. Do not send outreach. Do not assume integration is complete. Verify your own outputs. Use the free tier to test limits. If you hit a wall, contact support with your run ID. We built this for clarity. We removed the fluff. We removed the fake promises. What remains is a working tool. Use it. Best, The Zambo Team

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.
