Google Books API

Search Google Books through Google's official Books API: volume id, title, subtitle, authors, publisher, published date, description, text snippet, ISBN-10 and ISBN-13, page count, categories, average rating and rating count, language, cover thumbnails, preview, info and canonical links, sale info (saleability, list and retail price, buy link) and access info (viewability, public domain, ePub/PDF availability, web reader link). Search free text or by title, author, publisher, subject or ISBN; filter by language, books or magazines, previewable or free eBooks; sort by relevance or newest; up to 40 results per page and the first 1,000 results in total. Google limits how many API calls can be made per day; when that quota is used up the request fails with a clear, retryable error and is never charged, and so are empty pages.

This engine is built but paused: Waiting for a Google API key: the keyless Books API quota is used up for everyone. Switches on with GOOGLE_API_KEY on the worker. Join early access through the contact form and we'll email you on launch day.
