What does your agent want to do?

A task-indexed buyer's guide to the 527 APIs at Agent402 - written from the agent's side of the call. Each row maps a real goal to the cheapest tool that solves it. Browse the full category-organized catalogue at /tools, walk the multi-tool workflows at /skills, or ask the discovery endpoint directly: /api/find?q=<your task>.
