## Find a tool

Fous has 497 tools and more are built every day, so this file lists none of them. Find one the way an agent does:

- **Search** (no key needed): `GET https://api.fous.com/v1/catalog?query=flight+prices&limit=5` returns matching tools with their handle (`api`), summary and operations. `category=<id>` narrows it to a category below; `access=open` keeps tools that need no account or key. Over MCP, `fous_search_tools` does the same.
- **Exact inputs**: `GET https://api.fous.com/v1/catalog/detail?api=@hacker-news` gives a tool's operations with their input and output schemas; take inputs from there, never from a name. Over MCP, `fous_get_tool`.
- **A tool's own page**: `https://fous.com/tools/{name}.md`, `{name}` being its handle without the `@`: methods, fields, examples, and its own MCP server at `https://api.fous.com/mcp/tools/{name}`.
- **Every public tool**, for crawlers: https://fous.com/sitemap.xml.
