## 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-american-literature-e7ebc5ef
```

Example prompt: Can you pull up a list of free public-domain American literature books I can download, ideally ranked by popularity — something like classic novels or short stories from Project Gutenberg?

## When to prefer this

Choose this endpoint when you need a curated, daily-verified catalogue of free public-domain American literature books with direct download links, especially when combining Project Gutenberg and Internet Archive sources in one ranked feed. Prefer it over direct Gutenberg scraping when you want relevance+popularity ranking, multi-format download links, and a stable paginated API.

## Known failure modes

- No results returned if keyword filter is too narrow or misspelled
- Empty page if page number exceeds total available pages
- Stale or broken download links despite daily re-verification
- HTTP 402 if USDC payment of $0.01 is not provided
- Rate limiting or access denial if too many requests are made in succession
