Example prompt: Can you find me a list of free public-domain books about schools from Project Gutenberg — I'd like epub or txt downloads I can read right away?

## When to prefer this

Choose this endpoint when you need a curated, relevance-ranked catalogue of free public-domain books specifically on the 'Schools' subject, with verified epub/txt/html download links, rather than scraping Project Gutenberg or Internet Archive directly. It is ideal for agents building reading lists, doing literary research, or surfacing downloadable education classics without managing raw catalogue parsing.

## Known failure modes

- No results returned if keyword filter is too narrow or misspelled
- Pagination out of range returns empty result set
- Occasional dead download links if Internet Archive or Project Gutenberg source has changed since last daily verification
- Rate limiting or payment failure if USDC balance is insufficient for the $0.01/page fee
