Good afternoon! Tell me how to get the current exchange rates in JSON. I need a currency converter. As I understand it, the exchange rate at the National Bank is simply not suitable. Need an average value from different sources? Do I need a search parser? Sorry for the noob questions..

Answer 1

Isn't the official rate of the central bank suitable?
If you need the opposite result, then you can take it from here
