Releases: USEPA/ccte-api-exposure
v1.1.0
Released October 1, 2025
Originating from the US EPA's Center of Computational Toxicology and Exposure (CCTE), the CTX Hazard API is a RESTful API designed to manage and provide Hazard data. It interacts with a PostgreSQL database and offers various endpoints for hazard information. More information on the CTX API development and utility, as well as guidance on how to technically access and use them, is available here: https://www.epa.gov/comptox-tools/computational-toxicology-and-exposure-apis
Updates
- 🚀 Server migration: Please be advised that we have upgraded our API infrastructure and the CTX APIs have migrated servers. Check out the new version of the CTX APIs, available at https://comptox.epa.gov/ctx-api/docs/, which now supports new endpoints and data versions. This upgrade is necessary to improve performance, ensure reliability, and increase capacity. v1.0 of CTX APIs available at “https://api-ccte.epa.gov/docs/” were decommissioned on October 1st, 2025.
- 🚀 New endpoints available for the Multimedia Monitoring Database (MMDB)
