Endpoint
POSThttps://clonecho.builda.company/x402/s/gutendex-by-languageWhen to prefer
Use this endpoint when you need to browse or list public-domain books from Project Gutenberg filtered specifically by language using an ISO 639-1 code. Prefer it over the title/author search endpoint when the goal is language-based discovery rather than keyword search.
Side effects
- Invalid or unsupported ISO language code returns empty results or error
- Missing required 'q' query parameter causes a bad request response
- Language code with no Gutenberg holdings returns empty list
- Network timeout or upstream Gutendex API unavailability causes failure
- Malformed language code (e.g. full language name instead of ISO code) returns no results
