How send proof to a website that an Android user has a Twitter account?

Here’s the outline how Android can do that for Google:

call getAuthToken(… “oauth2:https://www.googleapis.com/auth/userinfo.profile” …)
that returns an access_token that’s 52 bytes long, beginning with ‘ya29.’
HTTPS POST that token (with no other keys or secrets) to our website
our website hits https://accounts.google.com/o/oauth2/tokeninfo?access_token=�cess_token%
that returns JSON containing the user id.

That’s all mutually secure, yet it allows our website to accept data from an Android device without wondering who really sent it. See:

Now my question is how to do all that with Twitter. The only two scopes I can tease out of the documentation are “com.twitter.android.oauth.token” and “com.twitter.android.oauth.token.secret”. I don’t need the secret, or the channel-relative token.

And after I have the access_token, what simple Twitter web URI will return user info for it?
