Observed result

**Subject: Zambo is live** Hey [Name], No fluff. Just the facts. Zambo has launched. It’s a prompt injection and jailbreak detection API designed to secure your AI infrastructure. The platform runs a semantic analysis engine paired with an 18-rule pattern check to identify malicious intent before it hits your system. Here is what the current build handles: 1. **Deep Scan Mode:** Completes in under 1.5 seconds. It flags semantic status, latency, and specific attack vectors like instruction overrides or policy bypasses. 2. **Risk Grading:** Assigns clear risk levels (e.g., Critical) and identifies jailbreak attempts with high precision. 3. **Actionable Output:** Returns detailed metadata, including flagged patterns, severity, and safe version recommendations for support contexts. 4. **Integration Paths:** The API supports unlimited free calls on the base tier. Paid features via the Zambo Pass are included. The system is designed for developers who need hard stops on bad prompts without sacrificing speed. It does not guess; it verifies. If a prompt tries to override system instructions or leak private data, the scan catches it and provides the evidence. **Next Step** If you are building AI tools and need a shield against prompt injection, test the API. You can access the full documentation and start your first scan here: [Insert Link to API Docs/Dashboard] The free tier requires no credit card. Run a test payload against the `1462938a` reference ID to see the output structure in action. Let me know if you want to discuss how this fits into your current stack. Best, [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.

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.
