Our API directory now includes 111 semantic APIs. The newest is the RACAI Linguistic API. The most popular, in terms of mashups, is the MusicBrainz API. We list 29 MusicBrainz mashups. Below you’ll find some more stats from the directory, including the entire list of semantic APIs.
This past week 10 new mashups were added to our mashup directory and 36 different APIs were used to build them.

Last April we wrote about How Twitter’s 1 API Gave Birth to 43 New APIs. One year later, there are now 86 Twitter-derived APIs in our directory. The growth of Twitter-based APIs outpaced Twitter mashups, an area we also saw a lot of growth. There are now nearly 600 Twitter mashups. It wasn’t even a year ago that we marked the 400 Twitter mashup milestone.
Sentiment Analysis is a growing feature of several applications that we see today. The trend is not surprising given the fact that the billions of messages per day are flowing in and out of several services on the web. Twitter, being one of the largest generators of data, is seeing its data mined in various ways to provide everything from movie reviews, predicting the result of a sporting event and much more.
This week we had 64 new APIs added to our API directory including a visual CAPTCHA service, genealogy service, user profile service, sentiment analysis for twitter service and cloud storage service. We also covered two of these APIs with full blog posts. We looked into iFixIt, the World’s First Fix-it API and deadpooled Google Base when it was axed in favor of two new shopping APIs. Below is more detail on all 64 of these new APIs.
