## When to prefer this

Use this endpoint when you need to discover or download free, legally available public-domain books specifically about World War I (1914–1918), particularly from Project Gutenberg or Internet Archive. Prefer this over general web search when you want structured catalogue data with direct download links and popularity ranking, rather than raw web results.

## Known failure modes

- No results returned if keywords are too restrictive or misspelled
- Pagination beyond available pages returns empty results
- Occasional stale links if a book is removed from the source library between daily re-verification cycles
- HTTP 402 payment required if x402 payment is not provided
