Gutendex

Gutendex is a free, open JSON web API that provides metadata for over 70,000 public domain books from Project Gutenberg—one of the world's largest collections of free ebooks. The API allows developers to search and filter the complete Project Gutenberg catalog by title, author, language, subject, copyright status, and more, returning structured data including book titles, author names, download counts, available formats, and cover image URLs. Gutendex requires no API key or authentication, making it easy to integrate for research, content discovery, digital library applications, and data analysis projects.
