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 Geospatial APIs or grab a chart widget already built from the APIs.

About the APIs

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

The web content and data APIs out of service until further notice. Check back here or on our GitHub site for updates—we’ll keep you informed as to the progress. Contact us at with questions.
