The user drags and drops an image onto the Cheapflights banner, which captures and analyses it, then feeds the detailed content description of the image to multiple service APIs to establish if the photo shows a singer, actor or sports star. This information is then fed to ticket sale services, such as Ticketmaster or Songkick, to find out when and where next public event is taking place. The Cheapflights API is then used to search for the best flights to that event from the user’s location. Flight search results are then sent back and displayed in the banner within a few seconds. (http://unclegrey.dk)
