Some APIs accept requests for public resources, in which case the request must be sent with an API key in lieu of a token. This function provides an API key for limited use in prototyping and for testing and documentation of gargle itself. This key may be deleted or rotated at any time. There are no guarantees about which APIs are enabled. DO NOT USE THIS IN A PACKAGE or for anything other than interactive, small-scale experimentation.
You can get your own API key, without these limitations. See the How to get your own API credentials vignette for more details.
