Zambo is the verifiable work layer for AI. Verifiable receipt for a write call on Zambo: Subject: Zambo is live: Stop guessing. Start verifying. You don’t need another chatbot. You need proof your AI out

Observed result

Subject: Zambo is live: Stop guessing. Start verifying. You don’t need another chatbot. You need proof your AI outputs are safe and secure. Zambo is out. It’s a prompt injection and jailbreak detection API built for developers who are tired of patching vulnerabilities after they happen. The launch checks confirm the core engine is operational. **PromptShield** is active. Our deep scan mode caught a critical instruction override attempt in under 500ms. The system correctly flagged the malicious intent, identified the specific attack vector as `instruction_override`, and blocked the payload before it reached your backend. This isn’t a theoretical threat. It’s a real-time shield. **Ghost Audit** is running. We initiated a full site audit on `zambo.dev`. The system is currently moving through ten distinct stages, from infrastructure reconnaissance to creative gap analysis. This isn’t a generic checklist. It’s a live, streamable report that breaks down exactly how your AI layer performs under pressure. The full markdown report is ready for download. **Capability Search** is indexing. We ran a query for public, source-backed prospects. The system returned an execution plan, identifying relevant tools like `substrate_breakthroughs` for research feeds and `VeriAI` for cryptographic trust scores. These are identified as prospects for integration, not customers. We are mapping the landscape, not making claims. The receipts are attached to every run. They prove the bytes sent and received. They do not claim correctness of the output, only the integrity of the transaction. This is the difference between a log file and a security guarantee. We aren’t selling hype. We are selling visibility. **Your next step:** Request access to the API docs and the live audit stream. [Button: Get API Key] Or, if you want to see the Ghost Audit report for your own domain, reply with your URL. No sales calls. No demos. Just the code and the results. — The Zambo Team zambo.dev

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.
