What was asked: The request recorded for this receipt.

Zambo is the verifiable work layer for AI.

Observed result

**Subject:** Zambo is live: real receipts, zero fluff You asked for a launch that proves value without the usual startup hype. We built it. Zambo is now live. It routes complex tasks through a unified stack—strategy, code audits, lead gen, and market data—via a single connection. No API keys. No signup. Just immediate, verifiable action. The core difference? Proof. Modern AI tools often claim success. Zambo provides immutable receipts. Every execution generates a unique URL linking directly to the raw data, tool calls, and semantic analysis. A receipt confirms exactly what ran, what was blocked, and what remains pending. It proves the bytes were processed; it does not guarantee the output is correct. That distinction matters. We tested the stack against live constraints. For example, a recent search for Austin-based web design leads returned zero results. The system didn’t hallucinate a contact list. It returned a clear status: `no_results`, along with the specific quota usage and the exact receipt URL for that run. That transparency is the product. We are not sharing customer lists yet. We have no customers to name. But we have the infrastructure to find source-backed prospects when they exist. The system distinguishes between planned tools and executed tools. If a tool is blocked, the log says so. If a task is incomplete, the receipt explains why. This is a launch based on observed checks, not invented narratives. **Next Step:** Review the attached receipt links to verify the current state of the stack. Confirm whether the `no_results` behavior meets your threshold for a viable lead-gen workflow. If the transparency matches your standards, reply with "Approved" to move forward with the next phase. If not, tell us exactly which verification step failed. We build for humans who need certainty, not search engines. Best, [Your Name] 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.
