The SEER API is a RESTful Web service that supports various SEER Program data sets and mapping. This service is available to developers who wish to incorporate SEER resources into their own systems. These resources include databases and tools developed to enhance registry operations and quality improvement. The SEER API is designed for integration into registry computer systems and is not designed to be accessed by end-users.
The goal of SEER API is to provide a centralized repository of SEER Program tools that is available to all programming environments and operating systems. The API is based on REST principles, therefore, it is very easy to write and test applications. You can use your browser to access URLs and to test APIs. Any programming language that can read HTTP data from a URL can use web services. Results are returned in JSON format which can be easily parsed and interpreted. See the Usage page for language-specific examples.
The SEER API powers a variety of SEER tools, including:
The Surveillance, Epidemiology and End Results (SEER) Program is a premier source for cancer statistics in the United States. The SEER Program collects information on incidence, prevalence and survival from specific geographic areas representing 28 percent of the US population and reports on all these data plus cancer mortality data for the entire country.
November 5th, 2014
The Disease (/rest/disease/:version) and Glossary (/rest/glossary/:version) search APIs were modified. If you use the search API you will most likely need to make changes to your code.
September 29th, 2014
The SEER*Rx APIs (/rest/rx) were modified to match the structure of the disease and glossary APIs. The Rx data is now going to be updated regularly.
A new set of APIs (/rest/surgery) were added to give access to SEER Site-Specific Surgery Codes. The current data comes from Appendix C on the SEER web site.

A Changelog section was added to document all API changes.
January 17th, 2014
The Hematopoietic and Lymphoid Neoplasm API was replaced with the Disease API. The new API contains the same types of diseases as before but will also include Solid Tumors as well. The following changes are now in place:
Full documentation for the new API can be found on the API documentation page.
