This web service allows you to programmatically query a historical exchange rate for a number of currencies, from January 1971 onwards, using exchange rates from the Federal Reserve and European Central Bank (ECB). It is currently free for use in low-volume and non-commercial settings.
The data from this service are those downloadable from the ECB's Euro foreign exchange reference rates website, and the US Federal Reserve's H.10 Foreign Exchange Rates. The ECB rates are updated every working day around 3 p.m. CET, this service should fetch updates within two hours. The Fed only releases one weekly update with daily rates for the past week.
Historical rates are available starting from 1971 and up to today. Some currencies may not be available for all dates
(such as the Euro before 1999). Each request made to
/getrate service uses the exchange rate for the day specified, or the last day before
that when no exact match is available (for instance during weekends).
This service is free for personal and non-profit use. If you use it, consider dropping me a line or leave a comment at this blog post. Donations to cover hosting costs are always welcome.
If you plan to make heavy use of this service, or want to use it for commercial purposes, please contact me in advance.
