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 website content (including charts and publications) and 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 once, and gain universal acceess 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 (and widgets for embedding charts) are currently out of service while we redesign our site. The GIS APIs are available. Check back here or on our GitHub site for updates—we’ll keep you informed as to the progress. Contact us at with questions.
