Application Programming Interface (API)

Application Programming Interfaces are used to pass data between applications. EPA has several publicly available APIs that can be used to interact with our open data. EPA uses api.data.gov as an API management service and tool for the public to sign up for API keys. 

Available APIs 

Below is a list of some of EPA's available APIs that provide access to different datasets.

API Strategy 

EPA has a Draft API Strategy that describes how we use and manage APIs.
