Important Notes on Exchange Rates
Rates are indicative: The exchange rates provided by the Frankfurter API are mid-market rates sourced from the European Central Bank. These are reference rates, not transaction rates. Your bank or money transfer service will apply a margin (spread) to these rates. Rate updates: The ECB publishes rates once per working day around 16:00 CET. Rates do not change on weekends or public holidays. Data accuracy: While we strive to provide accurate and up-to-date rates, we recommend verifying critical exchange rates with your financial institution before making significant currency transactions. Rates shown are for informational purposes only and should not be used as the sole basis for financial decisions.
