Since the /key endpoint is being depreciated, there is no other way (that I found) to get the key information, other than the .getKey or implementing a custom client to get the headers.
My suggestion is to add the ability to get headers when having any reply from the API, E.G PlayerReply has a .getRateLimit, .getRateRemaining, and .getRateReset, something that all replies will have.
