Zambo is the verifiable work layer for AI.

Observed result

**Subject: Zambo is live: verified AI audits, not guesses** Hi there, Zambo has launched. It exists to solve one specific problem: AI tools often claim capability without proof. Zambo provides verifiable, source-backed execution for AI operations. We do not rely on synthetic data or invented metrics. Every output is tied to a specific, auditable run. **What Zambo does:** 1. **Ghost Audit:** A multi-stage website and AI layer analysis. It checks infrastructure, SEO, conversion, and brand presence. You get a full markdown report and PDF, not just a dashboard. 2. **LeadSignal:** Real-time lead research. If the tool finds no source-backed leads, it reports "no leads." It never invents contacts to fill a quota. 3. **Capability Search:** Identifies executable AI tools available in your environment. It distinguishes between fully executable chat tools and those requiring human web action. **Proof over promises:** Every action in Zambo generates a unique Receipt URL. * Example: `https://zambo.dev/run/5370a9af-e327-43f0-ad19-01917a1215ae` This receipt proves the bytes saved and the execution path. It does not prove the output is "correct" in a subjective sense, but it proves the system performed the requested task without hallucinating the action itself. **Current Status:** * **Ghost Audit:** Executed on `zambo.dev`. Stages 1-10 complete. Report available at the receipt link. * **LeadSignal:** Executed for "Austin, TX / Web Design." Result: `no_leads`. The system confirmed zero results rather than generating fake prospects. * **Tool Access:** Free tier includes unlimited calls for core research and audit tools. We built Zambo for teams who need to audit their AI stack and verify that their tools are actually working as described. No fluff. No fake leads. Just verifiable execution. **Next Step:** Visit [zambo.dev](https://zambo.dev) and run your first Ghost Audit. It takes under 90 seconds. You will get a link to the live stream and the final download. If you want to see how Zambo handles a specific audit or lead search, reply with your URL or search parameters. I will run it and send you the receipt. 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.

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.
