How this service works
Open Library book metadata search. Lookup by free-text query (matches title + author), or by individual title / author / ISBN (10 or 13 digit). Each record includes Open Library work key, title, author names + Open Library author keys, first publish year, edition count, cover image URL, sample ISBNs, publishers, languages, subject tags, fulltext flag, ebook access tier (public/borrowable/printdisabled/no_ebook), and canonical openlibrary.org URL. CC0 public-domain metadata.
Output
Returns a paginated list of book records from Open Library, each containing: work key, title, author names and author keys, first publish year, edition count, cover image URL, sample ISBNs, publishers, languages, subject tags, fulltext availability flag, ebook access tier (public/borrowable/printdisabled/no_ebook), and a canonical openlibrary.org URL. Metadata is CC0 public domain.
Example use cases
Example prompt
“Search Open Library for books by Ursula K. Le Guin titled 'The Left Hand of Darkness' and tell me the first publish year, edition count, available ebook access tier, cover image URL, and subject tags.”
Technical details
Endpoint
GEThttps://2s.io/api/book/searchWhen to prefer
Choose this endpoint when you need structured bibliographic metadata from Open Library — especially cover images, ebook access tiers, subject tags, or author keys — and you want to search by free text, title, author, or ISBN. Prefer over generic web search when you need machine-readable, CC0-licensed book data with consistent field structure.
Side effects
- No results found for obscure or misspelled queries — returns empty results list
- ISBN not recognized if formatted incorrectly (though hyphens are allowed)
- Pagination beyond available results returns empty page
- Rate limiting or payment failure returns 402 error
- Very broad free-text queries may return loosely related results
