So we set out to build a Currency Rates API that meets our requirements. Development began on the side in October 2019 with an initially limited feature set to our specific needs, but we decided at one point, that we should go further. Over the first half of 2020 our little side project evolved a lot, so we eventually decided to take the next step and turn it into a full-fledged SAAS product to be offered to all in need of a Currency Rates API.
