Someone asked me to if i know any open API that can be used to access basic information of a Google plus user profile. I Googled the problem and found an API, called Portable Contacts API . This API is designed to allows a client application to access contact and social networking information under the Portable Contacts standard.
You can access Google+ profile information just with user ID
Its what you want, you can get users basic info like name, profile images and profile url etc; using this simple JSON API.
Here "116599978027440206136" is my Google ID. Redirect your browser to plus.google.com/me and see it in address bar.
Go write your Google+ widget, or hovercard!!
