There's a more API friendly endpoint to do this that returns a nice JSON response, like this:

  {"input01":{"Valid":"false","ErrorMessage":"That username is taken. Try another.","Errors":{"GmailAddress":"That username is taken. Try another."},"ErrorData":[""]},"Locale":"en"}

Checked and it still works too. Ported to node and added to: https://github.com/mikemaccana/is-gmail-account-valid
