## When to prefer this

Choose this endpoint when you need a curated, daily-verified catalogue of free public-domain books specifically on the 'Seafaring life' Library of Congress subject, with direct download links in multiple formats. It is preferable over scraping Project Gutenberg directly because it aggregates both Gutenberg and Internet Archive, applies popularity ranking, and supports keyword filtering by title or author. Best suited for reading list generation, research, or curriculum building around nautical and maritime literature.

## Known failure modes

- No results returned if keyword filter is too specific or misspelled
- Catalogue may lag up to 24 hours on newly added works (re-verified daily)
- Payment failure if USDC balance insufficient for $0.01 per call
- Empty page if page number exceeds available results
- Occasional dead download links if upstream Project Gutenberg/Internet Archive URLs have changed
