Observed result

Subject: Zambo is live: catching bad prompts before they hit your API You are likely testing AI guardrails right now. If you are building with LLMs, you know the risk: a single jailbreak attempt can expose your system or leak sensitive data. Zambo solves this. It is a prompt injection and jailbreak detection API designed to sit directly in your request pipeline. Here is what it does: 1. Scans incoming prompts for malicious patterns like instruction overrides and data exfiltration attempts. 2. Returns a clear verdict: safe, risky, or blocked. 3. Provides a detailed receipt for every scan, proving exactly what was checked and why. This is not a black box. You get line-by-line visibility into the threat. If a user tries to bypass your safety rules, Zambo flags it in milliseconds. Why this matters now: Relying on model-level refusals is no longer enough. Attackers are sophisticated. They use subtle phrasing to trick models into revealing system prompts or executing harmful actions. Zambo adds a dedicated security layer that operates independently of the LLM itself. The integration is simple. You send the prompt to Zambo, then to your model. If Zambo flags a threat, you reject the request before it reaches your infrastructure. We built this for developers who need certainty. No guessing. No vague confidence scores. Just clear, actionable security decisions. Start testing today. You can access the API via our documentation at [Zambo API Docs]. A free tier is available for initial testing, so you can verify its effectiveness against your specific use cases immediately. If you have questions about integration or need help configuring thresholds, reply to this email. We read every message. Stay secure, The Zambo Team [Zambo Website]

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.
