This past week 20 new mashups were add to our mashup directory and 28 different APIs were used to build them. Some of the newer or less frequently seen APIs include the Global Biodiversity Information Facility API, Glue API, Google Maps Data API, Shizzow API, Yahoo Placemaker API, and the Yahoo Search Marketing API. The most often used APIs this week are Google Maps, Last.fm, and Twitter. And the top three categories of APIs used were: Social (4 APIs, 9 mashups), Mapping (4 APIs, 10 mashups), and Advertising (3 APIs, 3 mashups).
Take a look at our API directory and you will quickly note that the Google Maps API continues to reign as the most popular API used for mashups. As the API continues to gain momentum, several new utilities have emerged to improve the user experience (or UX as it has come to be known).
At ProgrammableWeb we have been monitoring the emergence of mashups and APIs since 2005, and while there has always been steady growth, this year has seen an accelerating acceptance of APIs as a business strategy. The most recent evidence is that over 60 API entries have been added to our database in the last 30 days.
