The Invisiblehand API brings this cleverly named browser add-on focused on finding the lowest price for something that the user is shopping for to a wider audience. Constantly updating prices on millions of products from books to air fares, Invisiblehand stands out for its ability to learn about new products it hasn't seen before. The documentation indicates this is a RESTful API with JSON responses.
Keek, social video network, recently announced the release of the Keek API. Alongside the API launch, Keek established a developer portal that includes tools and resources to assist developers in integrating Keek with third party applications. The Keek API grants developers access to public keeks (i.e. 36 second video updates), search, user profiles, klusters, and more.
