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 historical changes that were made to this asset. Typically, once an API is published on ProgrammableWeb.com, the data we keep about that asset gets updated over the course of its life. For example, the endpoint or home page of the documentation might change. As a means of enforcing the integrity of our data, every time a non-trivial change is made to the data we keep about an asset, we require the entry of some changelog text before that change can be saved. This way, we have a great audit trail of all activity surrounding the asset. For each asset, the changelogs begins with the moment an asset is approved for publication on ProgrammableWeb. If you spot an error in our data and believe that a record needs to be updated in some way, the ProgrammableWeb team would very much like to hear from you at firstname.lastname@example.org
So far, we don't have a record of any changes to this API
