This area connects developers and researchers with machine-readable web content, publications, and charts. APIs for ERS' data products will start rolling out later this year.

The API supports REST formatted requests. Responses are returned in JSON or XML, depending on the content type specified in the request header.

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

Ready to start? Visit the REST Paths, Using the API, and Website Content API pages. And please tell us about your use of our APIs. ERS's efforts are part of the Digital Government Strategy.
