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-public-domain-books-on-paris-france-97c47c50
```

Example prompt: Can you find me a list of free public-domain books about Paris, France — ideally ones by Victor Hugo — with epub download links?

## When to prefer this

Choose this endpoint when you need a curated, relevance-ranked catalogue of public-domain books specifically about Paris, France, with ready-to-use download links and daily-fresh metadata. Prefer it over raw Project Gutenberg scraping when you want reliable pagination, author/title filtering, and multi-source aggregation (Gutenberg + Internet Archive) in a single call.

## Known failure modes

- No results returned if query keywords don't match any indexed titles or authors
- Pagination out of range returns empty result set
- Temporary upstream unavailability from Project Gutenberg or Internet Archive may cause stale or missing entries
- Payment failure (x402) if USDC balance insufficient — call not processed
