Zambo is the verifiable work layer for AI.

Observed result

**Subject: Zambo is live: verified research, zero hallucinations** We stopped guessing about AI reliability. Zambo is now live, offering a new standard for verified intelligence. We’ve integrated a deep semantic analysis engine that flags injection risks and jailbreak attempts in real-time, ensuring your outputs are secure and compliant. This isn’t just a feature; it’s a fundamental shift in how you deploy AI tools with confidence. Our launch includes three core components. First, the `substrate_breakthroughs` tool provides a read-only research feed with 51 lifeforms for adversarial research, available on the free tier with unlimited calls. Second, the `Leadsignal` module executes targeted lead searches. In our initial Austin web design test, it returned zero results. That is the correct behavior. It refused to invent contacts. It prioritized accuracy over volume. Third, we’ve integrated VeriAI for cryptographic trust scoring, though this currently requires a human web action flow. We are launching with transparency: we do not have customer testimonials yet. We have receipts. Every execution generates a unique URL, such as `https://zambo.dev/run/079d3bf9...`, which proves the saved bytes of the output. A receipt confirms what was generated. It does not guarantee the answer is factually correct, but it guarantees the system behaved as designed. We are sharing our internal scan logs, including a blocked "critical" injection risk, to demonstrate the security layer in action. We are not here to sell you a tool. We are here to show you how a tool should work. **Next Step:** If you want to test the security layer or the research feed, use Zambo to hand this over to your team. You can access the free tier immediately at `https://zambo.dev`. No credit card. No sales calls. Just the tools, the receipts, and the truth. See you in the feed, The Zambo Team

This is the saved result preview, not proof that the answer was correct.

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.

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.
