How do I use apiclient.discovery.build to get an email address?

[Zak]

 I'm trying to return the users email address after authorizing with scope "https://www.googleapis.com/auth/userinfo.email". I've tried the following:

service = build('userinfo', 'v1', http=http)
service = build('userinfo.email', 'v1', http=http)
service = build('email', 'v1', http=http)
service = build('profile', 'v1', http=http)
service = build('profile.email', 'v1', http=http)

 but all I get is UnknownApiNameOrVersion errors. What is the proper service I should be referencing to get an email address?

The list of APIs and the name and version to pass into build()
are available here:

http://api-python-client-doc.appspot.com/

The name and version are the last two columns on that page.

I believe the API you want is oauth2:
