The current version of the Open PHACTS API is version 2.1. Below are links to the API documentation. Our new release came out 2016-05 with new SureChEMBL patent data & updated pathways data.

Please note that version 1.4 of the API was decommissioned in late Mar 2016. If you have any questions about transitioning to new versions of the API, please don’t hesitate to get in touch via our support portal.

1.5 Decommissioning will also happen in the coming months as users transition properly to 2.1. We are happy to discuss how to help you move to the newest version of data and API


We also have a version independent URL for the API that always points to the latest API. This helps moving between versions easier. Our support pages explain more.

For our members there is a preview version of the API; please get in touch if you have questions or would like access to this.
