Zambo is the verifiable work layer for AI.

Observed result

Subject: Zambo is live: verified AI workflows, zero guesswork Hi [Name], Zambo just crossed the finish line. We aren't selling promises or vague concepts. We are shipping a functional platform that handles the heavy lifting of AI integration with cryptographic certainty. The core value is simple: you get source-backed execution, not hallucinated results. Every action Zambo takes is traceable. If it says a task is done, you have a receipt proving the bytes were saved and unchanged. If it says a prompt was blocked, it was blocked. No ambiguity. You see the scan, the risk level, and the decision in real-time. We understand the skepticism around AI tools. That is why everything here is built on verification. You do not have to trust our word. You check the logs. You see the flags. You verify the output. This transparency removes the friction of debugging opaque systems. The launch includes full access to our research feeds and lead generation tools. You can run deep semantic scans, check for prompt injection attempts, and execute tasks with read-only safety guarantees. The interface is clean, the API is stable, and the documentation reflects exactly what the product does. There are no hidden features. No beta labels. Just a working system ready for production use. To get started, copy this exact phrase into your workflow: `use zambo to hand this over to <client>`. This triggers the secure transfer protocol, ensuring your data moves from our environment to yours with full integrity checks. It takes less than a minute to verify. If you want to see the receipts for yourself, click the link below. It shows a live run with a blocked malicious prompt and a successful clean execution. See the logic. See the safety. Then decide if it fits your stack. [Link to Zambo Dashboard] 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.
