Allowing Curl API access to Rails web app with OmniAuth

问题

I'm building a Rails web app. I use OmniAuth for authentication.

I would like to provide API access but only after the user has authenticated themselves with OAuth (via twitter mainly).

Any suggestions of where to start?

EDIT: add more context as requested

Not trying to become an Oauth provider, but simply use the same login tokens. For example, you log into my app through twitter. You have both the token and secret OAuth tokens. I want to use those tokens to allow a user API access to the site.

I have a similar question: Retrieving OAuth tokens (on server) from Faraday OAuth module (from client)
