Zambo is the verifiable work layer for AI.

Observed result

Subject: Zambo is live: One key, thirty-five tools, zero signup Hi [Name], We are out of beta. Zambo is now a universal entry point for AI-driven work, routing thirty-five distinct capabilities through a single MCP connection. No API keys. No credit cards. No signup forms. This launch solves a specific friction: context switching. Instead of juggling separate interfaces for strategy, code audits, lead generation, and market data, you now have one consistent interface. The system handles the routing; you focus on the outcome. Here is what is working right now: 1. **Universal Routing:** One prompt triggers the right tool. Whether you need a code repair, a contractor lead list, or a strategic plan, the stack identifies the path. 2. **Transparent Execution:** We distinguish clearly between tools that are *planned* and tools that have *executed*. A receipt confirms saved bytes, not just a claim of completion. You see the proof. 3. **Accessible Intelligence:** The current free tier allows twenty total free calls per day across work tools. This is enough to validate workflows and test specific branches without friction. We ran a live test on the new lead generation module. The system queried for source-backed prospects in Austin for web design. It returned zero results because the data simply isn’t there right now. That honesty is the point. We do not guess. We do not pad lists with unverified names. We tell you when the data is missing, so you can adjust your search parameters rather than waste time on dead ends. This is a tool for operators who need reliable signals, not noise. It works with your existing AI setup, extending its reach rather than replacing it. **Next Step:** Click this link to view the live receipt from our test run. It shows exactly how the system handles a query, returns the result, and documents the state. [View Live Receipt](https://zambo.dev/run/87e630d1-f09c-406b-afb6-e670171d152e) If this aligns with your current stack, let’s set up a five-minute call to map your first three use cases. If not, no hard feelings. 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.
