Enterprises rarely move as quickly as the rest of the web. Many, including us at ProgrammableWeb, have been saying for some time that big companies will embrace the open API movement. It appears this may be happening in earnest now, as our directory hits the milestone of 8,000 APIs. And it makes sense, because APIs are helping companies do business, with the tradeoff between adding an external dependency being out-shined by the ability to move faster building upon someone else's expertise.
Our API directory now includes 38 scheduling APIs. The newest is the T Dispatch Passengers API. The most popular, in terms of mashups, is the Buffer API. We list 1 Buffer mashup. Below you'll find some more stats from the directory, including the entire list of scheduling APIs.
