Documentation for ver 2. of the TCIA API
The documentation for the latest version of the API is available here 


This document describes v2 of the TCIA programmatic Interface or  REST API implementation.  This API is designed for use by developers of image analysis and data mining tools to directly query the public resources of TCIA and retrieve information into their applications.  The API complements the existing web interface but eliminates the need for users to visit the TCIA web pages to select and download images then upload them into their viewing and analysis applications. The TCIA Programmatic Interface is based on a middleware platform called Project Bindaas, developed by Emory University and uses REST web service technologies.

The API is a RESTful interface, accessed through web URLs.  There is no software that an application developer needs to download in order to use the API. The application developer can build their own access routines using just the API documentation provided.  The interface employs a set of predefined query functions (see REST API Directory) that access TCIA databases.

If you are interested in using the API and have any questions, please contact us at

What's new

The following characteristics apply to all TCIA APIs:

Getting Started with the TCIA API

The following characteristics apply to all TCIA APIs:

BaseURL BaseURL includes the version number of this API (v2 in this example)
Query ParametersCollection=TCGA-GBM &
Formatformat=csvSome APIs support CSV/HTML/XML/JSON, while others only support a single return type.
Therefore this is required only in instances where multiple return types are supported.

API Reference

The full API consists of a base URL followed by the api and the query parameters in that order.

API Metadata

The API now supports the ability to programmatically access the metadata about your API. This information is provided as a JSON document and includes:

Name of API
Free text description
List of Query Parameters
Supported Return Types
A description of the returned attributes: Name, DICOM Tag and Description

The returned metadata conforms to the following JSON schema

Let us say we wanted metadata for the getPatientStudy query from our earlier example. The query would look as follows: 

Or in other words, the query would have the following structure:

(Warning) Don’t forget to include the api-key in either HTTP headers or the URL of the API.

Testing the API

There are two RESTful servers provided by TCIA. A test system is loaded with a small set of known data to allow you to test your applications. The production system is configured to use the full TCIA database. The query format is the same for both systems. The base URLs are:
