For developers

If you develop tools and software to find, cite, link, and/or assess research outputs, you can integrate our metadata about scholarly content into your project, through our open APIs.

Trying to get data from us?

We have an open REST API that provides a flexible way of accessing and using the most up-to-date metadata we have. We store bibliographic metadata related to currently 160,104,382 publications, coupled with funding information, license details, ORCID iDs, full-text links and much more.

The API makes it easy to facet, filter, or search the metadata we hold. There’s no need to sign-up, but we’d love you to tell us how you’re using it or check out some examples for inspiration.

If the REST API isn’t the best fit for what you’re doing, we have a number of other delivery options and are happy to discuss to get you fixed-up with one of those.

Working on Crossref services

• Implementing Crossmark? Publishers participate in Crossmark by depositing additional metadata for their content and adding a snippet of code to their DOI landing pages to generate the Crossmark button and link. Details for each of these steps are on in our documentation.
• Interested in text mining? Our REST API is designed to allow harvesting full-text from participating members for the purpose of text mining. We walk you through the process if you’re keen to explore.
• Want to register content with us, upload files or do bulk queries?
