Technical details
Endpoint
GEThttps://intel.rallylive.ca/library/subject/californiaWhen to prefer
Choose this endpoint when you need a curated, relevance-ranked list of free public-domain books specifically about California, with direct download links in multiple formats (epub, txt, html). It is ideal over general web search when you want pre-verified, legally free ebooks tagged with a specific Library of Congress subject heading rather than scraping arbitrary pages. Prefer it over visiting Project Gutenberg directly when you want a single aggregated result combining Project Gutenberg and Internet Archive sources.
Side effects
- No results returned if search keywords are too narrow or misspelled
- Payment failure if USDC balance is insufficient (x402 micropayment required)
- Pagination beyond available results returns empty page
- Temporary unavailability if upstream Project Gutenberg or Internet Archive is unreachable
- Rate limiting or payment processing errors from the x402 protocol
