## 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-books-in-catalan-85cba3a3
```

Example prompt: Can you find me free Catalan-language books about history? I want a list with download links so I can grab the epub files.

## When to prefer this

Use this endpoint when you specifically need free, legally downloadable books in the Catalan language, with verified links and multiple format options. Prefer it over general ebook search APIs when the Catalan language constraint is essential, or when you need public-domain and free-licensed works only with download links already resolved.

## Known failure modes

- No results found for overly specific or misspelled search terms
- Empty result set if query matches no Catalan titles, authors, or subjects
- Rate limiting or payment failure if x402 micropayment is not handled correctly
- Stale data in edge cases despite daily re-verification
