Get and set the API key used to make requests to the Epidata API. Without a key, requests may be subject to rate limits and other limitations.
get_api_key()save_api_key()
For get_api_key(), returns the current API key as a string, or
"" if none is set.
We recommend you register for an API key. While most endpoints are available without one, there are limits on API usage for anonymous users, including a rate limit. If you regularly request large amounts of data, please consider registering for an API key.
API keys are strings read from the environment variable DELPHI_EPIDATA_KEY.
We recommend setting your key with save_api_key(), which will modify an
applicable .Renviron file, which will be read in automatically when you
start future R sessions (see ?Startup for details on
.Renviron files). Alternatively, you can modify the environment variable at
the command line before/while launching R, or inside an R session with
Sys.setenv(), but these will not persist across sessions.
Once an API key is set, it is automatically used for all requests made by functions in this package.
