Of the many APIs we published this week, eight were highlighted on the blog by our team of writers. In this post, we’ll illuminate those eight by throwing them into the spotlight. The eight included the Invisible Hand API. Invisible Hand, web browser add-on, is dedicated to informing the user of the cheapest price on millions of products ranging from flight discounts to tooth brushes. It does so by matching UPC, ISBN and EANs to products from the search box. Furthermore, it includes roughly 700 retailers and 600 Airlines and has saved users a breath taking one billin dollars since its inception. To learn more about the Invisible Hand API visit the Invisible Hand site as well as the Invisible Hand API blog post.
