Books

26 APIs

Book APIs return bibliographic metadata, cover images, full texts of public domain works and religious scriptures. ISBN lookups suit catalogues and reading lists; check whether cover images may be hotlinked or must be downloaded. Public domain text sources are a good fit for reading apps, though metadata quality varies between sources.

Open Library returns book records and covers without a key, Gutendex searches Project Gutenberg's catalogue, and Google Books searches a large book index. PoetryDB serves poems with CORS enabled, Crossref Metadata Search covers scholarly works, and Bible-api and Quran Cloud return scripture text.
