Zambo is the verifiable work layer for AI.

Observed result

Subject: Zambo is live: research, verify, and hand off The days of guessing at AI workflows are over. Zambo is here to streamline how you find, verify, and deliver intelligence. Our launch focus is simple: accuracy. We don’t just generate text; we ground our outputs in verifiable data. When you run a search, you get a clear path to the source. If we can’t find a real lead or a factual answer, we tell you. We never invent names, fabricate sales, or guess at customer details. A receipt from Zambo proves the data was saved, not that it’s perfect—but it does prove the process was transparent. This matters for your bottom line. Trust is earned through consistency. Zambo provides the tools to maintain that consistency without the manual overhead. You can start with our research capabilities immediately. For example, our LeadSignal tool scans for source-backed prospects. If it finds no real leads in a specific market, it reports zero results rather than padding the list with fictional contacts. That honesty saves you time and protects your brand reputation. We also offer specialized tools like Substrate Breakthroughs for deep-dive AI research and VeriAI integration for cryptographic trust scoring. These aren’t just features; they are safeguards against the noise of unverified AI outputs. Our free tier allows you to test these core functions without commitment. You can run scans, check receipts, and explore the research feeds right now. The interface is designed for speed, giving you the data you need to make decisions, not just the content you need to read. Ready to see how it works? 1. Click here to access the Zambo dashboard. 2. Run a test search using your own criteria. 3. Check the receipt URL to verify the execution path. If you have questions about specific integrations or how to apply this to your current workflow, reply directly. We read every message. Let’s build something reliable. Best, The Zambo Team

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.
