+      A bunch of rates between currencies, taken from our invoicing cycle in February 2024.

+          The rate between the two currencies. You should read it as the amount of target currency you get for each unit of base currency.
+
+          For example: for the combination EUR-GBP, a rate of 0.8 means you get 0.8 GBP for 1 EUR.
+
+          Rates between same-currency pairs are always one.
