Switch in under an hour.

Both APIs speak JSON over HTTPS, so migrating from ExchangeRate-API is usually a base-URL and response-shape change. Follow the migration guide, run both side by side on your free trial, and cut over when the numbers check out.

"We had intermittent failures with our previous currency exchange API provider. We switched to fastFOREX — setup was easy, and we always get fast response times. That's all we need."

Beyond Bath & Bed — switched to fastFOREX API
