Computational Toxicology and Exposure APIs

Application Programming Interfaces (APIs) allow programmatic access to the EPA’s computational  toxicology and exposure data resources. APIs provided by EPA enable users to extract specific data from various databases and integrate them into their applications. APIs can effectively automate the process of accessing and downloading the data, such as data used to populate the CompTox Chemicals Dashboard. 

Check out the Computational Toxicology and Exposure API (CTX API) API User Guide for more information on the CTX API development and utility, as well as guidance on how to technically access and use them.

As part of EPA’s commitment to provide “open data”, these CTX APIs are publicly available data resources for anyone to access and use. These APIs are hosted on cloud.gov, a secure cloud environment managed by the General Services Administration specifically for U.S. federal government applications. These data are free of all copyright restrictions, and are fully and freely available for both non-commercial and commercial use. All data are also available for download on the Downloadable Computational Toxicology Data page.
