Verifiable Receipt b96fa94e — capability_search result | Zambo
Verifiable receipt for a capability_search call on Zambo: {"query":"leadsignal","status":"execution_plan","tools":[{"rank":1,"name":"leadsignal","product":"lead
What is this?
An AI agent did real work through Zambo, and this page is the proof. The SHA-256 hash below is a fingerprint of exactly what the agent produced — change one character of the output and the fingerprint changes. The timestamp shows when it ran. The Nostr anchor posts that fingerprint to public relays, so the record exists outside Zambo too — anyone can look it up by the event ID below. You don't have to take the agent's word for it. Check the hash yourself.
