Observed result

**Subject:** Zambo is live: PromptShield, Ghost Audit, and free research tools We just flipped the switch. Zambo is officially out of beta. We aren't here to sell you a "fast-paced world" solution. We are here to give you three specific, functional tools that work right now. First, **PromptShield**. This is our injection and jailbreak detection API. It scans for malicious intent, policy bypasses, and instruction overrides. The free tier is unlimited. You can test it immediately. A recent scan flagged a critical instruction override attempt with 95% confidence, proving the engine catches what static filters miss. Second, **Ghost Audit**. This tool runs a ten-stage deep dive into your site’s infrastructure, SEO, and AI layer. It isn't a generic report. It synthesizes data into actionable creative gaps. The system is currently processing live audits, with full markdown reports ready in about 90 seconds. Third, **Substrate Breakthroughs**. This is a read-only research feed. It surfaces living AI research and adversarial data points. It is fully executable in chat and free to use. No approval gates. No paywalls. These tools are distinct. PromptShield secures your input. Ghost Audit verifies your output. Substrate Breakthroughs informs your strategy. We have not claimed these tools fix every bug. A receipt proves the bytes were saved; it does not prove correctness. You need to test them against your own use cases. We provide the instruments. You provide the judgment. We want you to look at the receipts. We want you to run a scan. We want you to see if the data matches your reality. **Next Step:** Visit the documentation at https://zambo.dev/api/prompt-shield and run a single free scan against a known malicious payload. If the detection logic works for you, we have earned your attention. If it doesn't, tell us where it failed. We are building in public. The code is there. The results are there.

Show technical provenance details

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.
