v1.0.0

ctxR v1.0.0

Released July 4, 2024

The R software, ctxR, is open-source software used to interact with the Computational Toxicology and Exposure (CTX) APIs developed by the US EPA Center for Computational Toxicology and Exposure. ctxR is available at the Comprehensive R Archive Network (CRAN) (https://cran.r-project.org/package=ctxR). The CTX APIs provide users access in a programmatic manner to the data stored in the CompTox Chemicals Dashboard (CCD) (https://comptox.epa.gov/dashboard/) and other CTX resources (https://www.epa.gov/comptox-tools).

Before using the APIs, the user must acquire an API key; more information on acquiring an API key may be found at the CTX APIs landing page (https://www.epa.gov/comptox-tools/computational-toxicology-and-exposure-apis).

ctxR includes several vignettes to get new users started with interacting with different endpoints of the CTX APIs. The API endpoints are organized into four broad areas, Chemical API, Hazard API, Bioactivity API, and Exposure API. Currently, ctxR supports all four data domains and will continue to develop as additional endpoints in existing or new organizational areas are released.
