Develop applications, products or services based on our vast corpus of searchable research papers
Free real-time machine access to the world's largest collection of open access papers.
Harmonised access to data from across the network of CORE providers.
Direct machine access to full texts of research papers.
Accessible and easy to understand description of using CORE API.
CORE collects, harmonises and enriches large quantities of both metadata and full text research articles from thousands of data providers. On top of this continuously growing corpus, we provide a truly unique API providing real-time machine access to both the metadata and full texts of research papers, enabling developers to build and run innovative applications on top of CORE's content.

“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.”

Find out how other institutions benefited from CORE API
CORE harvests and aggregates information of research papers collected from institutional and subject repositories, and open access and hybrid journals, and makes the content available via an API. The CORE API offers a wealth of metadata and full text content from its many data providers. For ORA (Oxford University Research Archive), the use of the CORE API offers an opportunity to enhance workflows and streamline the process of reviewing and curating articles for inclusion in the repository...
