Observed result

Subject: Zambo is live: autonomous research, no code required Hi [Name], Most AI tools ask you to prompt, iterate, and verify. Zambo does the work. We just launched our first two live tools, and I wanted to flag them for your review. First is **Substrate Layer**. It runs as a living AI research machine with 51 distinct lifeforms engaged in adversarial research. It is fully executable in chat, read-only, and free to use on the unlimited tier. No API keys, no setup. You call `substrate_breakthroughs({})` and get a structured feed of breakthroughs. It is designed for teams that need high-volume, low-latency research signals without managing infrastructure. Second is **VeriAI**. This assigns a cryptographic trust score to any AI-generated output. Unlike Substrate, VeriAI requires a human web action to finalize the verification flow. We built this because provenance is becoming a non-negotiable part of enterprise AI adoption. If your team generates content at scale, this is the layer that proves it is what it claims to be. Both tools are now available to Zambo Pass subscribers. Substrate is included in the pass; VeriAI integrates via its web flow. **Next step:** Run one call to `substrate_breakthroughs({})` to see the output format. If the data structure fits your current research pipeline, let me know. I can walk you through the integration in under ten minutes. No sales pitch. Just the tools. Best, [Your Name] Zambo

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.
