• find_data

  Describe the data you need in plain language (e.g. 'Apple risk factors 2023', 'is this token a honeypot', 'is this email deliverable', 'read this page'). Searches this server's datasets first, then the whole Professor Sausages catalog, and returns matching endpoints with method, URL, price, and how to call them. Free.

  Parameters:

  • task (required) — string — What you're trying to find or do, in your own words

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
