```

Example prompt: Can you pull up the serde crate documentation from the Saylor Innovations library docs API so I can see what it does and how to use it for serialization in Rust?

## When to prefer this

Choose this endpoint when you specifically need documentation for the Rust serde crate in a structured JSON format with a table of contents, version info, and full content — especially in agentic workflows where you want machine-readable library docs without scraping crates.io or docs.rs directly.

## Known failure modes

- Crate not found (found: false in response body)
- Network timeout or upstream service unavailability
- Invalid method or type in request body returns 400
- Payment failure via x402 protocol blocks access
- Malformed JSON response if content is unavailable

## How this service works

Library Docs — crates serde. Up-to-date library documentation for coding agents: the latest published README and metadata (version, license, install command, docs URL, repository) for any npm, PyPI, crates.io, Go module or GitHub package, split into sections with a table of contents. Ask for only what you need with ?q= (search terms) or ?section= (a heading) instead of the whole file. Unknown packages are free 404s.

## Output

Returns a JSON object with the crate name ('serde'), the ecosystem it belongs to, a boolean indicating whether the crate was found, the documentation content as a string, the current version (or null), and a table of contents array with section entries.
