Live APINo matching results. Try fewer filters.
Use random currency pairs as a geography prompt, an exchange-rate guessing game, or a quick converter. Enter ISO currency codes for a specific pair, and optionally select a historical date.
Guess the rate, then reveal it
Choose a base and quote currency, or leave both open, and the page shows a pair with the exchange rate hidden until you reveal it. Add a date to see what the rate was on that day instead of today.
Where rates come from
Frankfurter publishes reference rates from the European Central Bank, updated on working days. They are mid-market rates for comparison, not the rate a bank or card will give you.
Frequently asked questions
Which source supplies the rates?
Frankfurter, which republishes European Central Bank reference rates.
Can I look up a historical rate?
Yes. Set the historical date filter and reveal the rate for that day.
Why does my bank show a different number?
Banks and cards add spreads and fees. The page shows the mid-market reference rate only.
