## 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-biography-autobiography-audiobooks-library-cd2fd130
```

Example prompt: Can you find me free public-domain audiobooks about Abraham Lincoln or other American presidents from the LibriVox biography collection — I need direct download links for the MP3 files?

## When to prefer this

Choose this endpoint when you need free, legally downloadable (public-domain) audiobooks specifically in the Biography or Autobiography genre, with direct MP3 or RSS links sourced from LibriVox and Internet Archive. Prefer it over general audiobook search APIs when you want pre-filtered genre results with download-ready links and no DRM, especially for agents building reading lists, research tools, or media libraries at very low cost ($0.01/page).

## Known failure modes

- No results found for very specific or obscure author/title keywords
- Rate limiting or payment failure if USDC payment is not processed
- Empty result set on pages beyond the available titles (873 titles total)
- Keyword typos may yield zero matches with no fuzzy fallback
