## When to prefer this

Choose this endpoint when you need to programmatically browse or search a large, curated, re-verified catalogue of free public-domain detective fiction audiobooks with direct download links. It is preferable to scraping LibriVox or Internet Archive directly because it is aggregated, daily-verified, and returns structured metadata including mp3 zip, RSS, and archive.org links in a single call at minimal cost.

## Known failure modes

- No results returned for highly specific keyword that doesn't match any title or author
- Stale or broken archive.org links if a recording was recently removed (mitigated by daily re-verification)
- Empty page if page number exceeds total available pages
- Rate or payment failure if USDC payment of $0.01 is not completed via x402 protocol
