How this service works
Book lookup by ISBN: title, authors, publisher, date and pages from Open Library. Input: an ISBN.
Output
A JSON object containing the book's title, subtitle (if any), list of authors, publisher(s), publish date, page count, source ('Open Library'), the Open Library URL, and the queried ISBN.
Example use cases
Identifying a book from a barcode
“I scanned a barcode on a book and got ISBN 978-0-7432-7356-5 — can you tell me what book this is, who wrote it, and when it was published?”
Building a reading list with full metadata
“I have these ISBNs from my shelf: 9780061965487 — can you fetch the title, author, publisher, and page count so I can add it to my reading list?”
Verifying edition details before purchasing
“Before I buy this used book, can you check ISBN 9780140449136 and tell me the publisher, publish date, and page count so I know which edition it is?”
Technical details
Endpoint
POSThttps://minty-sprout.onrender.com/v1/isbn-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have an ISBN (10 or 13 digit) and need structured bibliographic metadata — title, authors, publisher, publish date, and page count — without needing full-text search or complex filtering. It is ideal for enriching book records, verifying edition details, or identifying unknown books from barcodes. Prefer this over a general web search when you need clean, structured JSON output directly from a library data source.
Side effects
- ISBN not found in Open Library — returns an empty or null result
- Malformed ISBN input (non-numeric, wrong length) — may return an error or no match
- Very obscure or recently published books may lack complete metadata (missing pages, authors, etc.)
- Network timeout if Open Library API is slow or unavailable
