API Info

Introduction

The OncoKB™ data can be accessed through a REST API (Swagger Page). The API is defined and organized using swagger annotation. MAF file annotation is also possible by using OncoKB™ Annotator which is fully supported by using OncoKB™ REST APIs.

When you send API requests, you need a token before accessing the OncoKB™ data via its web API. Please visit OncoKB™ Data Access Page for more information about how to register an account and get an OncoKB™ API token.

Authentication

We are using standard Spring Security to protect all our services. In order to access the OncoKB™ data via its REST API, you need to specify your API token in the request header with

Authorization: Bearer [your token]

Your token will be available under your Account Settings after getting a license from the OncoKB™ Team.

OncoKB™ Instances

https://www.oncokb.org

This is the main instance and authenticated. If you have gotten a license from OncoKB™. Please use this instance for most accurate results.

https://demo.oncokb.org

Before committing to our license, you can use this website to test the API and other services freely. We included the full information of BRAF, TP53 and ROS1. The instance is not authenticated.

Annotation API Examples

If you have the access token and like to play around with our endpoints, please see the Swagger page. We only list GET methods here. They all have corresponding POST method available. Please see the Swagger page for more details.
