This page describes the representational state transfer application programming interface (REST API) implementations that can be used to access TCIA data and resources. The APIs complement the existing web interfaces and enable developers to build direct access to TCIA data into their applications using only the API documentation provided. The application developer must ensure that they and the users of their applications comply with the TCIA Data Usage Policy.
TCIA currently offers the following RESTful interfaces to the search and download functions enabled by the National Biomedical Imaging Archive (NBIA) software in the TCIA radiology portal.
- TCIA REST APIs: Originally developed using Project Bindaas with Emory University, these APIs provide access to public collections and do not require authentication or API keys to use them. The TCIA REST API Guide describes these APIs.
- NBIA REST APIs: Provided as part of the NBIA software, these APIs provide access to the search and download functions used in the TCIA radiology portal, and allow access to both public and limited access collections. The NBIA Search REST APIs allow you to perform basic queries and download data for image analysis on public collections. The NBIA Search with Authentication REST APIs allow you to perform basic queries on and download data for image analysis from public and restricted collections. The NBIA Advanced REST APIs also allow access to public and restricted collections, but are geared towards developers seeking to integrate searching and downloading TCIA data into their own web and desktop applications.
Note that new versions of the APIs may introduce new data types that have not yet been documented. If you are interested in using the APIs and have any questions, please contact the TCIA Help Desk.
