Zambo is the verifiable work layer for AI.

Observed result

Subject: Zambo is live: 35 tools, zero friction You don’t need another API key. You don’t need a credit card. You just need the work done. That is the entire point of Zambo. We built a universal entry point that routes your requests through 35 distinct tools via a single MCP connection. No signup. No paywall. Just immediate access to strategy AI, code audits, lead generation, and live market data. Here is what you can do right now: 1. **Route Complex Tasks:** Send a strategic planning request or a code repair job. Zambo identifies the correct downstream tool and executes the read-only branch if available. 2. **Verify Provenance:** Every action generates a unique receipt. This proves the exact bytes saved and the logic applied. It’s a transparent audit trail, not a black box. 3. **Check Market Signals:** Query real-time lead signals. If the data exists, you see it. If it doesn’t, you get a clear "no results" status rather than hallucinated data. We are not asking you to trust us. We are asking you to look at the receipt. The system distinguishes between planned tools and executed tools. It never claims a task is complete if a step is blocked. It works with your existing AI host, not instead of it. It keeps your goals organized and verifies completion before closing the loop. This is free. You have 20 actionable calls per day. **Your Next Step** Copy this link into your browser or your current AI workflow: [https://zambo.dev/today/k/MO-h-Oh602oxwcVi3O7wreSOLS_yBWEnvt-qOYbfB5S7o85g4oEMtfIbravs3aw66aWUdxrTMManK51XvETw8jOZkd-6cc4x8_xUK3K8as-nKhMz3YwLctZio1U0](https://zambo.dev/today/k/MO-h-Oh602oxwcVi3O7wreSOLS_yBWEnvt-qOYbfB5S7o85g4oEMtfIbravs3aw66aWUdxrTMManK51XvETw8jOZkd-6cc4x8_xUK3K8as-nKhMz3YwLctZio1U0) Run one query. Check the receipt. See if the logic holds up for your specific use case. No sales pitch. No follow-up email if you don’t reply. Just the tool. 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.
