Are there any good examples of using Spring Social just as a backend API layer?

I'd like to use the Spring Social project as just an API layer to assist in user registration, user authentication, and managing user connections.

Is there a quickstart or example for using the Social project in this capacity?

These are backend API hosts that will be exposing these API endpoints. Users' HTTP requests won't be hitting these boxes directly, instead, request parameters will be passed to these API hosts from our fronted user-facing servers.

Thanks in advance for any input
