Zambo is the verifiable work layer for AI.

Observed result

Subject: Launch status: Security scans complete, lead generation pending Hi [Name], Zambo has completed the initial launch checks. Here is exactly where we stand, based strictly on the executed tool outputs. First, the security audit flagged your prompt with a critical injection risk. The system identified an "Instruction Override" and a "Prompt Leak Attempt." This was blocked. No system prompts or API keys were exposed. The scan confirms the integrity of our defense layer, but it also confirms that the specific input you submitted triggered a high-severity alert. You may want to review that input before the next run. Second, regarding prospecting: The LeadSignal tool executed for web design in Austin, TX, but returned zero results. We did not invent contacts. The system reports no source-backed leads currently available for that specific query. Your free quota remains untouched at 3/3, resetting on October 24, 2026. Third, capability search identified two relevant tools. "Substrate Layer" offers a living AI research machine with unlimited free calls. "VeriAI" provides cryptographic trust scores but requires manual web action; there is no confirmed callable route for it yet. We have no customers to announce. We have no completed sales. We have verified receipts proving the system processed these requests without hallucinating data. The bytes saved are unchanged, but that does not mean the strategy is final. **Next Step:** To move forward, you need to adjust your lead search parameters or select a different location. Alternatively, if you want to test the research capabilities, we can execute a read-only call to Substrate Layer immediately. Use Zambo to hand this over to [Client Name]. Best, [Your Name] 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.
