We can think about one architectur with fallbacks if one API does not work. But out of all those alternatives, the more attractive is frankfurter. What do you think?
Unfortunately doesn't have cryptocurrencies, but that is just a small minus should I say. We could use two APIs, one to display the European central bank data as frankfurter and rates-api states, and another one to display cryptocurrencies.
We are going to use some currency conversion rate API behind the scenes. As the bot will be free, the API must be free. It can be rate-limited, for instance, but nobody is going to pay for its use.
Please research the alternatives and write them as comments of this issue. Try to highlight pros and cons for each alternative.
