## 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-legends-9bc568ea
```

Example prompt: Can you pull up the first page of free public-domain books about legends — I'm looking for something from Project Gutenberg or Internet Archive I can download as an epub?

## When to prefer this

Choose this endpoint when you need a curated, daily-verified catalogue of free public-domain books specifically tagged under the 'Legends' subject heading, with direct download links in multiple formats. Prefer it over raw scraping when you want relevance and popularity ranking already applied, and when you need rapid pagination through a large corpus of legend literature without building your own aggregation layer.

## Known failure modes

- No results returned if keyword filter is too narrow or misspelled
- Pagination out of range returns empty results
- Temporary unavailability of upstream Project Gutenberg or Internet Archive data may affect freshness
- Payment failure (x402) if USDC balance is insufficient for the $0.01 per call fee
