## 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 free-works-search-439302c4
```

Example prompt: Can you find me a free, legal download of 'Pride and Prejudice' — I'd like an epub or txt version if possible, and a link to grab it right now?

## When to prefer this

Use this endpoint when you need to find free, legally downloadable versions of books, audiobooks, or films — particularly public-domain classics. Prefer this over general web search when you specifically need verified rights status and direct download links, rather than just bibliographic information or purchase links. Best suited for classic literature, historical films, and works old enough to be public domain.

## Known failure modes

- No matches found for obscure or very specific queries — returns empty result set
- Query too broad may return many loosely related results with limited relevance ranking
- Copyrighted works will not appear — searches limited to free/public-domain catalogue only
- Download links may occasionally be stale if re-verification hasn't completed for a given record
- Non-Latin or rare language queries may return fewer results depending on catalogue coverage

## How this service works

Search a catalogue of free, legally downloadable works: public-domain books (Project Gutenberg), audiobooks (LibriVox), films and texts (Internet Archive collections), growing by tens of thousands of records a day and re-verified daily. Returns matching works with authors, year, language, rights status and direct download links (epub, txt, mp3, video files). Where to get it for free, with the link. $0.01 per search.

## Output

Returns a list of matching works with fields including title, author, publication year, language, rights/public-domain status, source collection (e.g. Project Gutenberg, LibriVox, Internet Archive), and direct download URLs in applicable formats (epub, txt, mp3, video).
