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).
Trendn aggregates the most viral and socially-shared content on the web. Ranking is based on social engagement, which refers to how interesting or relevant people have found an item or category to be. Examples of engagement include sharing with your friends, bookmarking an article, leaving a comment on a blog, or clicking a link to read a news item.
