Now that I've had a chance to use cointracking.info all night, I realize that what I need is an API when given the date/time, and a coin, it will return the dollar value at the date/time.
Does anyone know where I could get the historical dollar value of crypto coins through an API?  Thankyou

I need to calculate the dollar value of several thousands transactions (trades, mining and master nodes rewards) in CAD in order to calculate my capital gain. Is there an online database or interface that I could query to get the dollar value (in CAnadian Dollars) for BTC and various altcoins?  Thank you
