How this service works
Resolves book title, author, publication date, and page count from the public Open Library API by ISBN.
Output
Returns a JSON object with the book's title and author, a supported flag indicating whether the ISBN was found, a confidence level (e.g. 'high'), the data freshness date, any warnings, and a disclaimer about informational use only.
Example use cases
Identify a scanned book barcode
“I scanned a barcode on a book and got ISBN 9780743273565 — can you tell me what book this is and who wrote it?”
Enrich a reading list with metadata
“I have this ISBN from my reading list: 0061964360 — can you fetch the title and author so I can label it properly?”
Verify a book listing before purchase
“Before I buy this used book, can you confirm what the title and author are for ISBN 9780525559474?”
Technical details
Endpoint
POSThttps://bizintel-api.hahavoid0.workers.dev/product/open-libraryWhen to prefer
Choose this endpoint when you need quick, cheap bibliographic lookup by ISBN and don't require a full library catalog API integration. Ideal for AI agents enriching product data, reading lists, or book inventory systems. Best when you have a specific ISBN in hand and want title/author without managing API keys or subscriptions — pay-per-call at $0.01 USDC fits low-volume or sporadic lookups.
Side effects
- ISBN not found in Open Library — returns supported:false or low confidence
- Invalid ISBN format (not 10 or 13 digits) — likely validation error or empty result
- Ambiguous or duplicate ISBNs leading to low confidence result
- Open Library upstream unavailability causing timeout or error
- Newly published books not yet indexed returning no results
