Web Services

Public web services support the ECHO website and are available to web developers. The services allow developers to design custom applications utilizing a live feed of data from ECHO. EPA provides a collection of "GET" or query-only RESTlike (REpresentational State Transfer) services, available through a simple URL HTTP link and providing output in XML, JSON, or JSONP formats. Links to the documentation for using each of the services is posted on this page. For information on the data sources, see ECHO's About the Data page.
