Note that the Bank of Canada provides, for free, feeds of exchange rate data: https://www.bankofcanada.ca/rates/exchange/. It's only updated daily, but I think points out the difficult niche that currencyscoop would be able to go after. For anyone showing general prices on goods (like an online store), daily rates should be good enough, while anyone doing something like currency trading is going to need something much more accurate than what currencyscoop provides.
