This is the first API profile in what we are calling the "Growth Series." Mapbox provides an API that allows developers to create maps with rich data visualizations by using multiple data layers. This feature along with others has fueled an 11x growth in calls made to its API.
Twitter recently added more data to each tweet it returns via the API. Now your applications can access the number of retweets, whether you have retweeted a tweet and additional information about the user who wrote the tweet. The new information used to require subsequent calls to the Twitter API, or perhaps looking up a cached value from your own database.
