Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability aayat-ai-library-documentation-finder-c9e31126
```

Example prompt: Can you find the llms.txt documentation for the hono npm package so I can reference it while coding?

## When to prefer this

Use this endpoint when an AI coding agent needs to find machine-readable documentation (llms.txt / llms-full.txt) for a specific software library or package. Prefer this over general web search when you need structured, AI-optimized documentation with metadata like version, homepage, and repository links, and when you want to avoid scraping unstructured HTML docs. Ideal for coding agents that need to quickly locate the canonical documentation entry point for npm, PyPI, crates.io, or Go module packages.

## Known failure modes

- Library not found in specified ecosystem — empty found array returned
- No llms.txt or llms-full.txt present on the library's homepage — checked array shows what was tried
- Invalid ecosystem value — schema validation error
- Payment not received or insufficient USDC — 402 response before data is returned
- Domain resolution failure for the library's homepage — no documents found

## How this service works

Find the AI-ready docs for any library or API: checks the project's docs site (from its npm, PyPI, crates or Go metadata) or any company domain (docs., developers., /docs) for llms.txt and llms-full.txt files, with titles, sizes and page counts, plus homepage and repository. ?library=hono or ?site=stripe.com

## Output

Returns a JSON object with a list of found documentation files (URL, kind like llms.txt or llms-full.txt, byte size, link count, title, summary), the resolved package version, homepage, repository URL, a list of all addresses checked, and the timestamp of the check. May include a tip for more targeted doc retrieval.
