CORE API

Develop new applications with the CORE API

CORE API's screenshot
  • Key message 1

    Free real-time machine access to the world's largest collection of open access papers

  • Key message 2

    Harmonised access to data from across the network of CORE providers

  • Key message 3

    Direct machine access to full texts of research papers

CORE collects, processess, harmonises and enriches large quantities of metadata and full texts of research papers from many data providers. On top of this continuously growing collection, we provide a truly unique API offerring real-time machine access to both metadata and full texts of research papers, enabling developers to build and run innovative applications on top of CORE's content.

If you use CORE in your work, we kindly request you to cite one of our publications.

Where to start?

Please register to receive an API key and start testing the live examples.

A good starting point to start coding with our API is to follow the iPython notebook available on Github. In collaboration with rOpenSci you can find here an R client for the CORE API. All our SDKs are available here.

CTO, Iris AI AS

We are integrating the CORE API into our product, IRIS, because so far it is the open access portal that covers almost all open access content, provides easy to integrate API and has a powerful search querying engine. We want to make open access articles more easily accessible and more useful to researchers and the open public and we see the CORE API as a way to speed that up.

What’s included

The API is free to use for non-commercial purposes. If you want to use the CORE API in commercial applications, please contact us. Our free membership provides you with:

  • Machine access to the world's largest corpus of open access research papers, containing both metadata and full texts.
  • Detailed documentation on how to use the CORE API with live examples and wrappers to common programming languages.
  • One batch request or five single requests per 10 seconds. Need a faster rate? Contact us.
