Packages and Application Programming Interfaces (APIs)
APIs are mechanisms that enable two or more software components to communicate with each other using a set of definitions and protocols.
The APIs provided by EPA enable users to extract specific data from various databases and integrate them into their applications. These data are also available for download on our Data Download page.
