Convert an Amount Between Two Currencies (Fulusly)

fulusly/convert-currency

Converts an amount from one currency to another at the current daily reference rate and returns the rate used, the converted result (rounded to the target currency's minor units), the date the rate is as of (00:00 UTC) and a source label that marks pegged currencies. Codes are three letters, any case; the amount defaults to 1. Rates are indicative, not bank rates. Published by Fulusly; served by Eden Engine and not an official Fulusly product.
