Zambo is the verifiable work layer for AI.

Observed result

Subject: Zambo: The launch is live We shipped. Zambo is now live and ready for immediate use. It is a universal entry point for the Zambo Stack, routing requests through 35 tools via a single MCP connection. No API key. No signup. Just a free, daily allowance of 20 calls across work tools. The platform handles strategic planning, code audits, lead generation, and live market data. It does not replace your host AI; it works with it. Zambo organizes your goals, provides the next working step, and preserves receipts for verification. This distinction matters. It ensures you know exactly what executed and what remains planned. We ran a deep semantic scan on the launch infrastructure. The results are clear. The system is stable, the tools are responsive, and the provenance checks are passing. We did not test on live customer data. We tested on internal workflows. The receipts prove the bytes saved are unchanged. They do not prove business outcomes. They prove technical integrity. Right now, the tool is operating on a free tier. You have three lead signal calls remaining before the quota resets. The system is ready to route your first actionable task. Here is the path forward. 1. Visit the receipt link below to verify the live status. 2. Connect your host AI to the Zambo universal tool. 3. Issue your first command. Whether it is a code audit or a lead gen query, the tool will return a concrete route. If a live read-only branch is available, it executes. If not, it suggests the downstream tool. Do not assume success. Verify the receipt. Check the distinction between planned and executed tools. That is the only metric that matters for a clean launch. The infrastructure is sound. The logic is tight. The risk is on you to stop guessing and start routing. [Link: Verify Launch Receipt](https://zambo.dev/run/17c3d9eb-d294-4577-a2ce-1d1a5ba80bb2) Ready when you are.

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.
