Janrain was an Identity Provider (as a service) company based out of Portland, Oregon that was acquired by Akamai in 2019 and subsequently shutdown.

Many enterprises used them to store user data, help with social login, and proxy requests to Silo APIs.

Their home page was at: https://janrain.com/

API Docs were at: http://developers.janrain.com/rest-api

(note: could use Internet Archive versions of those pages before they went down)
