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 will provide a collection of "GET" or query-only web services, available through a simple URL HTTP link and providing output in XML, JSON, or JSONP formats. Documentation for using each of the services will be posted on this page.
Detailed Facility Report
The ECHO DFR REST Services (PDF) (95 pp, 436 K, About PDF) document describes the REST web services used to provide data for EPA's Enforcement and Compliance History Online (ECHO) Detailed Facility Report (DFR).
This is collection of “GET” or query-only web services that are available through a simple URL HTTP link and provide output in either XML, JSON, or JSONP formats. These services are available through an EPA application server that is exposed to the Internet. The base URL link for all DFR services is https://ofmpub.epa.gov/echo/dfr13_rest_services. The required input parameters are described in the document. (Note: Default Internet Explorer settings do not support the display of JSON results directly in the browser. Other browsers, such as Firefox and Google Chrome, do support display.)
All Data Facility Search
The ECHO All Data Search Results Services (PDF) (44 pp, 1.1 M, About PDF) document describes the REST services used to provide data for EPA's Enforcement and Compliance History Online (ECHO) All Data Facility Search.
