Subject: Zambo is live Hi [Name], Zambo is officially up and running. No more waiting periods or beta lists. You can start building immediately. We focused on one specific problem: prompt injection. It is the biggest security hole in current LLM applications, and most developers are blind to it. Zambo scans incoming prompts in real-time. It flags jailbreaks, policy bypasses, and instruction overrides before they reach your model. The detection engine is fast. It runs in under 1.2 seconds. That means you can add a security layer without adding latency to your user experience. The API is simple. You send the text; we send back a risk score and a detailed breakdown of the attack vector. If the risk is low, let it through. If it’s high, block it or route it to a human review. We built this because we were tired of patching holes with band-aids. You need a shield, not a fix. Here is what you get: * Real-time scanning for 18 known attack patterns. * Detailed logs showing exactly what triggered the alert. * A free tier to test the accuracy on your own data. We are not selling you a platform. We are giving you a tool. It works with any LLM provider. It does not lock you in. It just makes your AI safer. Check it out here: [Link to Zambo.dev] If you want to see how it handles a specific edge case you are worried about, send me the prompt. I will run it through the scanner and share the results with you. No strings attached. Let’s keep your AI secure. [Your Name] [Your Title] Zambo

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.
