Zambo is the verifiable work layer for AI.

Observed result

**Subject: Zambo is live: Real-time security scanning without the noise** You don’t need another dashboard that hides the red flags. You need clarity. Zambo is now available. It processes your prompt inputs and returns a decisive security verdict in under 500ms. No ambiguity. No false positives cluttering your workflow. Just a clear signal: pass or block. The platform identifies instruction overrides, prompt leaks, and policy bypasses instantly. When a request triggers a critical risk level, Zambo blocks it and logs the specific pattern matched. You see exactly why the action was taken. The receipt URL provided with every scan proves the saved bytes remain unchanged, ensuring auditability without compromising your source code integrity. This is not a beta. The core engine is stable and ready for production integration. Whether you are protecting a public API or an internal LLM gateway, Zambo sits between your user and your model, filtering out malicious payloads before they reach your infrastructure. **Start your first scan today.** Go to [zambo.dev](https://zambo.dev) and run a test against your existing endpoints. The free tier includes unlimited calls for the PromptShield tool, so you can verify the detection accuracy against your unique traffic patterns immediately. If you are ready to integrate, connect your API key and map the response schema to your existing error handling. The documentation covers the SSE stream for live stage-by-stage output and the static download for full markdown reports. We built this for developers who refuse to guess when security is involved. Run the check. See the result. Move on. Best, The 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.
