## 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-welsh-language-books-library-9a210587
```

Example prompt: Can you find me a list of free Welsh-language books I can download — I'm looking for anything by popular Welsh authors or classic Welsh literature, ideally in epub or txt format?

## When to prefer this

Use this endpoint when you specifically need Welsh-language (cy) books from public-domain or free-licensed collections. It is pre-filtered for Welsh content and aggregates across both Project Gutenberg and Internet Archive, saving the effort of querying those sources separately and filtering by language. Prefer this over generic library APIs when the user explicitly wants Welsh-language texts with verified download links.

## Known failure modes

- No results found if the search query does not match any Welsh titles, authors, or subjects
- Empty page returned if page number exceeds available results
- Service unavailable if the upstream aggregation from Project Gutenberg or Internet Archive fails
- Stale or missing links if daily re-verification has not yet completed

## How this service works

Free books in Welsh: public-domain and free-licensed Welsh-language works from Project Gutenberg and Internet Archive with download links (epub, txt, html, scans), most popular first; add words to search within Welsh titles, authors and subjects. Re-verified daily. $0.01 per page of 20.

## Output

A paginated list (20 items per page) of Welsh-language books including title, author, subjects, and download links in formats such as epub, txt, html, and scanned images, sorted by popularity. Results are re-verified daily against Project Gutenberg and Internet Archive sources.
