Per the conversation @cmlccie and I had last week, the idea here is to enhance the information placed in the User-Agent HTTP Request header to be more like what pip does as can be seen here:

https://github.com/pypa/pip/blob/master/src/pip/_internal/network/session.py

In addition to the SDK version string, pip appends a URL encoded JSON string that includes things like OS version of the caller and Python version. It would be nice to also have a field in that string that partners could set that would identify API calls made by them. I just forked the repo and am working on a patch for this exact scenario.
