Zambo is the verifiable work layer for AI.

Observed result

Subject: Zambo is live: autonomous research, verified safety, and real lead signals [Name], Zambo just launched. It handles the heavy lifting of business operations by automating complex workflows without compromising on security or accuracy. The core difference is transparency. Zambo doesn’t just guess; it proves its work. Every task generates a unique receipt that verifies the exact data processed and the specific actions taken. You get a clear audit trail for every interaction. Security is built-in, not bolted on. The platform includes a deep semantic analysis engine that scans every prompt for injection risks, jailbreak attempts, and policy violations. It flags critical threats like instruction overrides or data extraction attempts before they reach your systems. If a prompt is malicious, Zambo blocks it and provides a detailed risk assessment, ensuring your data remains safe. Beyond safety, Zambo connects you with actionable insights. The LeadSignal tool searches for source-backed prospects in specific industries and locations. It doesn’t invent leads. If no real, verified contacts exist for a search, it tells you plainly. This ensures you spend time only on genuine opportunities, not fabricated data. Whether you need to monitor AI research breakthroughs or verify the trust score of generated outputs, Zambo provides the tools to do so with precision. It’s designed to be a reliable partner in your workflow, handling the complex verification and research while you focus on strategy. Ready to see how it works? Click here to run your first free task: https://zambo.dev/day-pass/ You can also check the live dashboard to see recent execution logs and safety scans in action. Let’s get your first workflow running. Best, [Your Name] [Your Title] Zambo

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.
