Euro foreign-exchange reference rates from the European Central Bank for 30 currencies - USD, GBP, JPY, CHF, TRY, CNY, INR, BRL and more - with cross-rates derived through EUR (USD/TRY, GBP/JPY, anything against anything) and an optional daily series up to 90 business days. The response says plainly what these are: published once per business day around 16:00 CET, not a live market rate and not tradeable.
