## When to prefer this

Choose this endpoint when you specifically need free, public-domain books categorized under the Library of Congress 'American wit and humor' subject heading, with verified download links across formats (epub, txt, html). Prefer it over general web search when you want pre-curated, rights-confirmed results from Project Gutenberg and Internet Archive, re-verified daily, with relevance and popularity ranking and the ability to filter by title or author keywords.

## Known failure modes

- No results returned if query keywords match no titles or authors in the catalogue
- Empty page response if page number exceeds available results
- Stale download links if a source (Project Gutenberg/Internet Archive) restructures URLs between daily re-verification cycles
- Payment failure if USDC balance is insufficient for the $0.01 per call fee
