## How to call it through Zero

```sh
zero fetch --capability free-books-folklore-ff4b10b9
```

Example prompt: Can you find me a list of free public-domain folklore books I can download? I'm especially interested in anything by Andrew Lang or with 'fairy' in the title.

## When to prefer this

Choose this endpoint when you need to discover or retrieve free, legally downloadable public-domain books specifically on the subject of folklore. It is ideal when you want pre-filtered, relevance-ranked results from trusted library sources (Project Gutenberg + Internet Archive) rather than scraping the web yourself. Prefer it over general web search when you need actual download links and metadata rather than just bibliographic references.

## Known failure modes

- No results returned if search terms are too narrow or misspelled
- Pagination beyond available results returns empty page
- Occasional dead download links if source catalog changes between daily re-verification cycles
- Rate limiting or payment failure if x402 microtransaction is not correctly handled
