The service provides exchange rates for many currencies worldwide, allowing applications to convert amounts for transactions and to assess risk of changes in exchange rates over time. It is available as a widget to be embedded in HTML pages or as a web service with SOAP API.
API methods support retrieval of a foreign exchange rate for any pair of currencies by multiplying a "currency factor" by one currency value to determine the other value. Methods also support listing of datasets providing currency factors, providers of datasets, and timestamps of the datasets, which allows evaluation of data reliability.
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.
