Developer Center / APIs


Open Library offers a suite of APIs to help developers get up and running with our data. This includes RESTful APIs, which make Open Library data availabile in JSON, YAML and RDF/XML formats. There's also an earlier, now deprecated JSON API which is preserved for backward compatibility.

Try out our interactive OpenAPI sandbox!

NOTE: If making use of our APIs regularly or frequently, be sure to specify a user agent with a link or email we can use to contact you if we notice a spike in requests. Thank you!

Bulk Access

Please do not use our APIs for bulk download of Open Library data because this affects our ability to serve patrons. We make our data publicly available each month for partners. If you want a dump of complete data, please read about our Bulk Download options, or email us at openlibrary@archive.org.

More APIs

Did you know, nearly every page on Open Library is or has an API. You can return structured bibliographic data for any page by adding a .rdf/.json/.yml extension to the end of any Open Library identifier. For instance: https://openlibrary.org/works/OL15626917W.json or https://openlibrary.org/authors/OL33421A.json. Many pages, such as the Books, Authors, and Lists, will include links to their RDF and JSON formats.

Questions

We encourage developers to ask questions by opening issues on GitHub and on our gitter chat channel.
