How to determine if email is a Google Account?

Question

Me and some guys here are working on a launch. We are currently using the Google OpenID API to manage registration and login to our application, but we want to move to an easier user registration model. And for this we need to know if there is a way to detect that email (and not gmail) is already a Google account. Is there a way to get this information from the Google Single Sign-On API?

Thanks for the help!:)

Answer 1

You cannot do this. I do not think Google can tell you this without the consent of the user.
