Google+ API, call API without access token

I implemented G+ and FB login button and got access token successfully. But I didn't save it in my server. For new business, I need to get display name and image of authorized users. For Facebook intergration, I can use :

https://graph.facebook.com/userId?fields=picture.width(720).height(720),name&access_token=APP_ID|APP_SECRET

Are there any similar way for G+ API to get public information of G+ user (image, name, email..) without the missing access token?
