This is an unofficial Pinterest API. Pinterest is a pinboard-style photo sharing website that allows users to create and manage theme-based image collections such as events, interests, hobbies, and more. Users can browse other pinboards for inspiration, 're-pin' images to their own pinboards, or 'like' photos. (Credits to http://pinterestapi.co,uk for the user-specific Pinterest APIs).
