Ultimate Solution For Foreign Exchange Rates And Currency Conversion API

An exchange rate is the amount of one currency it costs to purchase another. They provide critical currency exchange rate information to investors and travelers as well as businesses with international customers. If exchange rates are something that is important to you, your investments, or your business, what would you say to the option of having access to a list of hundreds of exchange rates within one API? 

If that is something you are interested in, it is possible with Fixer.io which is a powerful exchange rate api.
