Social auth in rails api

Hi folks,

I want to rewrite my rails app in order to work as an API. I decided to
go with rails_api however rails suits me needs as well. The bottleneck
for me at this point is finding an easy way to provide authentication
using REST API. I have limited experience in omniauth gem that’s why I
am writing this post)

Is there anything that could provide me with at least 3 social networks
login solutions out of the box for rails api? I have not found any quick
solution so I am thinking to switch to python cuz it would take much
less time if I had an ability just to reuse some library.
