## 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-dogs-89280c6c
```

Example prompt: Can you show me a list of free public-domain books about dogs I can download — ideally popular ones — with links to epub or txt files?

## When to prefer this

Choose this endpoint when you need a curated, pre-filtered list of free public-domain books specifically on the subject of dogs, with ready-to-use download links in multiple formats. It is better than scraping Project Gutenberg directly because it aggregates both Gutenberg and Internet Archive, ranks results by popularity, and is re-verified daily. Prefer it over general book search APIs when you specifically need the dogs subject area and want free, legally downloadable content.

## Known failure modes

- No results returned if query terms are too restrictive and match nothing in the catalogue
- Rate limiting or payment failure if USDC microtransaction is not processed
- Stale or broken download links if upstream Project Gutenberg or Internet Archive URLs change between daily re-verification cycles
- Empty response if the catalogue index is temporarily unavailable

## Output
