## 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-russia-045022c5
```

Example prompt: Can you pull up the first page of free public-domain books about Russia — I want epub or txt download links for the most popular ones I can read offline?

## When to prefer this

Choose this endpoint when you need a curated, daily-verified catalogue of free public-domain books specifically on the topic of Russia, with ready-made download links in multiple formats. It aggregates both Project Gutenberg (415+ titles) and Internet Archive sources in one call, saving you from scraping multiple libraries. Prefer it over general web searches when you want structured bibliographic data with direct download URLs rather than search engine snippets.

## Known failure modes

- No results returned if filter terms (title/author) are too narrow or misspelled
- Payment failure if USDC balance is insufficient for the $0.01 per call fee
- Empty catalogue page if page number exceeds total available pages
- Stale or broken download links if source repositories have changed between daily reverifications
- Slow response if Internet Archive scans are being fetched
