How this service works
List Project Gutenberg books filtered by language (ISO code, e.g. fr, de, es) and sorted by popularity via Gutendex. Returns count and matching books. Keyless. Useful for building multilingual public-domain reading datasets.
Output
Returns a JSON object containing a total count of matching books and an array of book records filtered by the requested ISO language code, ordered by popularity, sourced from the Gutendex API (Project Gutenberg index). Each book record typically includes title, author(s), language, download count, and format links.
Example use cases
Multilingual reading dataset builder
“I'm building a dataset of public-domain texts in Spanish — can you fetch me the most popular Gutenberg books available in Spanish so I can see how many there are and what titles come up?”
Language learning resource discovery
“What are the most popular free classic books available in German on Project Gutenberg? Pull the full list sorted by popularity so I can recommend them to language learners.”
Comparative literature research
“I need to compare how many public-domain books are available in Italian versus Portuguese on Project Gutenberg — can you fetch the popular books for Italian first?”
Technical details
Endpoint
POSThttps://proxy.suverse.io/v1/data/suverse-gutenberg-by-languageWhen to prefer
Choose this endpoint when you need to discover or enumerate public-domain books from Project Gutenberg filtered by a specific language without requiring an API key. It is especially useful for building multilingual reading datasets, powering language-specific ebook discovery features, or conducting comparative literature research across languages. Prefer it over direct Gutenberg API calls when operating within an x402 payment-enabled agentic workflow that needs a managed proxy.
Side effects
- Invalid or unsupported ISO language code returns empty results or an error
- Network timeout from upstream Gutendex API
- Payment failure or insufficient USDC balance (x402 protocol)
- Malformed request body causes 400 error
- No books found for rare language codes returns count of 0 with empty list
