## When to prefer this

Choose this endpoint when you need a curated, paginated catalogue of free public-domain books specifically in the 'Literature, Modern' Library of Congress subject area, with direct download links. It is ideal over generic web search when you want verified, consistently formatted results from trusted sources (Project Gutenberg, Internet Archive) with daily freshness guarantees, and when cost per page of results matters at $0.01 per 20 results.

## Known failure modes

- No results returned if query keywords don't match any titles or authors in the catalogue
- Rate limiting or payment failure if USDC micropayment is not processed correctly
- Stale or broken download links if a source (Gutenberg/Archive) removes a title between daily verification cycles
- Empty result set for very specific keyword combinations with no matching works
