What was asked: The request recorded for this receipt.

Zambo is the verifiable work layer for AI.

Observed result

Subject: Zambo is live: Zero setup, full stack You don’t need another API key. You don’t need to sign up. You just need results. Zambo is out. It runs on a single MCP connection, routing your requests through 35 distinct tools. Strategy AI, code audits, lead generation, wallet intelligence, and live market data. It plugs into your existing host AI, working alongside it rather than replacing it. The core promise is simple: concrete routes, not vague suggestions. When you ask for an action, Zambo executes a live read-only branch if one is available. If not, it tells you exactly which downstream tool to call. No black boxes. No guessing. You preserve the receipt, verify the output, and move on. We built this for speed and transparency. Every run generates a verifiable receipt. That link proves the bytes saved. It does not guarantee the output is "correct" in a subjective sense, but it proves the system executed the request as logged. That distinction matters. It separates factual execution from opinion. Currently, Zambo offers 20 free calls per day across work tools. No credit card. No trial period. Just access. We are not claiming Zambo will solve every problem. It is a precision instrument. Use it for lead gen, code repair, or strategic planning. Verify the results. Keep the receipts.

Click it. See the data. Judge the utility. If this fits your workflow, connect the MCP endpoint. It takes seconds. If it doesn’t, ignore this email. No hard feelings. No follow-ups. Zambo works with you, not instead of you. Best, The Zambo Team

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.
