Details

To obtain an API key and enable services, go to https://www.epa.gov/comptox-tools/computational-toxicology-and-exposure-apis. This documentation shows you how to obtain an API key to allow access to the CTX APIs.

To tell ctxR about your API key, use register_ctx_api_key(), e.g. register_ctx_api_key(key = 'grbwigbwoginrowgbwibgdibdvinrginiwgo') (that's a fake key). This will set your API key for the current session, but if you restart R, you'll need to do it again. You can set it permanently by setting write = TRUEm see the examples. If you set it permanently it will be stored in a local file, and that will be accessed by ctxR persistently across sessions.

Users should be aware that the API key, a string of garbled characters/numbers/symbols, is a PRIVATE key - it uniquely identifies and authenticates you to CTX's services. If anyone gets your API key, they can use it to masquerade as you to CTX. To mitigate against users inadvertently sharing their keys, by default ctxR never displays a user's key in messages displayed to the console.

Users should be aware that ctxR has no mechanism with which to safeguard the private key once registered with R. That is to say, once you register your API key, any R function will have access to it. As a consequence, ctxR will not know if another function, potentially from a compromised package, accesses the key and uploads it to a third party. For this reason, when using ctxR we recommend a heightened sense of security and self-awareness: only use trusted packages, do not save the API keys in script files, etc.
