To spur innovative applications of ERS data in the public and private sectors, this area connects developers, researchers, and digital professionals with machine-readable data, web services, and other related technical resources. Use our Application Programming Interfaces (APIs) to gain programmatic access to select data (including GIS) - or grab our widgets already built from the APIs!

About the APIs

ERS uses the shared, interagency service to provide an optimized experience for users. Register for a key using the form below, and gain universal access to any Open Government data using the service. Use of this API is subject to ERS Terms of Service.

The APIs support REST-formatted requests.

The Charts of Note widget is an example of what a developer can do with the API. It offers a number of options for easily embedding these daily charts.
