What these numbers mean

Registry download counters count every fetch the registries report, including mirrors, CI, and repeat installs. Downloads are not people.

Public receipts are individual records anyone can open and check. They prove the saved result was not changed since it was saved. They never prove the answer was right.

Tool calls are executed calls on the Zambo MCP endpoint.

Registry counts come from the server-side aggregation of the registries’ own reporting. This page does not call registries from your browser. Public receipts and total tool calls load from the Zambo stats API.
