Your software that uses the programmatic interface requires an API-KEY. In this version of the programmatic interface, the API-KEY is used to identify the software application. You can obtain one API-KEY and use that for your application; you do not need a separate API-KEY for each user of your software.. To obtain and an API-Key please send a request to help@cancerimagingarchive.net or contact TCIA's help desk by phone at: +1 314-747-4254. Please see the coding examples in github: https://github.com/nadirsaghar/TCIA-REST-API-Client for guidance on how to incorporate the API-Key into your code. Once you have acquired an API-Key you will need to implement a minimal amount of software in your application to invoke the REST API.
