## How to call it through Zero

```sh
zero fetch --capability free-books-fairy-tales-428f1cdd
```

Example prompt: Can you show me a list of free public-domain fairy tale books I can download — maybe filter by Grimm or Andersen — with epub and text links included?

## When to prefer this

Choose this endpoint when you need a curated, ranked list of public-domain fairy tale books with direct download links, especially when sourcing from Project Gutenberg or Internet Archive. It is ideal for agents building reading lists, populating content libraries, or enabling users to download classic fairy tales for free. Prefer it over generic web search when you need structured bibliographic data with verified download links rather than unstructured HTML pages.

## Known failure modes

- No results returned if keyword filter is too restrictive or misspelled
- Pagination beyond available results returns empty page
- Downstream source (Project Gutenberg/Internet Archive) temporarily unavailable leading to stale or missing entries
- Payment failure (x402) if USDC balance is insufficient for $0.01/page charge
