First, I’d like to stress the fact that registration to use the API is voluntary and if you opt not to register an application but would like to use the API anyway, you can do so. The benefit to registering an application and using that application’s credentials to access the API is that you are allowed to make more requests than anonymous consumers of the API.
More information about how to register will be available as we release the application service to the public.
