Getting the user PUID: Azure Graph API

I have been using PowerShell to query details of my O365 users. Therein, I get a property called LiveId which appears to be the PUID. I want to get away from PowerShell. So, I used the Azure AD Graph API Helper:http://code.msdn.microsoft.com/windowsazure/Windows-Azure-AD-Graph-API-a8c72e18

This does give me my user list. But the User object does not have the PUID and a few more details which the PowerShell cmdlet is able to give me. Can you please help me with this one?

Thanks,

Karthik
