## 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-crime-mystery-fiction-audiobooks-librivox-ee5b109a
```

Example prompt: Can you find me free crime and mystery audiobooks I can download — ideally something by Arthur Conan Doyle or Agatha Christie — with direct MP3 links?

## When to prefer this

Choose this endpoint when you need a curated, daily-verified catalog of free public-domain Crime & Mystery Fiction audiobooks specifically from LibriVox, with direct download (MP3 zip), RSS, and archive.org links included per record. Prefer it over generic search when you want structured metadata (runtime, language) and reliable links without scraping LibriVox or Internet Archive yourself.

## Known failure modes

- No results returned if search keywords don't match any title or author in the catalog
- Payment failure (x402) if USDC balance is insufficient — call returns 402 rather than data
- Stale or broken archive.org/mp3 links if a title has been removed from Internet Archive since last daily re-verification
- Empty page if requested page number exceeds available results
