The online Forex API market is divided into two sections: Inexpensive, but unreliable open-source projects, and overpriced, but well-performing Enterprise-class APIs. At the currency layer, we aim to combine the strengths of both into one superior product — delivering highly accurate, reliable, and consistent currency exchange rates through a closely monitored API, making it available to small-scale businesses and startups, and conveniently low priced for larger companies.
