The process of taking your photos and sharing them online with your friends has never been easier. There are several services available to do that today like TwitPic, YFrog and others. The success of Instagram even led to an unofficial API, which was subsequently shut down to be eventually replaced with its official API. The photo sharing services space seems ripe for the emergence of APIs, which in turn might trigger the next round of innovation from developers.
Last year, the Executive branch of the US government made huge strides in opening up government controlled data to the developer community. Projects such as the Open Data Policy and the Machine Readable Executive Order have led the US government to develop an API strategy. Today, ProgrammableWeb takes a look at another open government API: the Annual Production Figures of United States Currency API.
