Observed result

Subject: Zambo Launch: Source-Backed Prospects & Substrate Layer Hi [Name], Skipping the pleasantries to share what we’ve validated for the Zambo launch. We focused strictly on execution plans and read-only research, ensuring no data was altered and no outreach was sent. Here is the current state of our capability search for public, source-backed prospective customers. We identified two primary tools in the AI research space. First is the Substrate Layer, a living AI research machine featuring 51 lifeforms and adversarial research capabilities. This tool is fully executable in chat, requires no approval, and is retry-safe. It is free on the unlimited tier and included in the Zambo Pass. Its relevance score sits at 52, driven by its fit for AI research. Second is VeriAI, which provides a cryptographic trust score for any AI-generated output. However, this tool requires a human web action. There is no confirmed callable Zambo MCP route for the public VeriAI product, so we must use its web flow at https://veriai.site. We have confirmed a receipt for this run at https://zambo.dev/run/a97a4a9d-f791-4b27-b579-db5c3b727e9f. This receipt proves the saved bytes remain unchanged; it does not verify the correctness of the underlying data. Please treat these entities as prospects only. We have not invented findings, customers, or sales. This is a research-only status. Your next step is to review the Substrate Layer’s free tier access. Confirm if you want to proceed with the read-only research feed for the adversarial lifeforms. Best, [Your Name]

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.
