About Big Book

Big Book API is a books data API offering search across a database of millions of titles by title, author, or ISBN, with filtering and sorting by rating and publish date. It also provides semantic search, allowing natural-language queries with automatic synonym, hypernym, and homonym understanding.

The API includes a recommendation feature that finds similar books and suggests titles based on stated interests. It is intended for developers building applications that need book search or discovery functionality.

A free API key, documentation, and SDKs are available, and the product is part of the Open Search group of APIs.
