The Xchangeonline API provides developers with currency conversion functionality and currency rounding functionality. All exchange rates are kept current. Developers simply call the API specifying the function(conversion or rounding), amount of money, the current currency, the desired currency value, and the API key giving them access to the service. The API then returns the value of the money in the currency desired. It also supports a wide variety of development platforms and over 100 different currencies.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
