Forex API

Our Forex API is used by over 15,800 developers worldwide. We provide a fast, reliable, API for your application.

Trusted Data Sources

Currency exchange API data is a minefield, so we only use the best sources to keep you safe.

Start Free

Track Usage

Use our customer portal to track usage and manage your account - simple.


From a few requests a day to hundreds per second - we've got you covered.

Currency API is fast.

Slow response times are a drag. They slow down your application which leaves your customers annoyed (who needs that?). Our response times are the best in the business, which will keep you and your customers happy.

Bank-level Security

Our competitors may use weaker security, but we use SHA-256 SSL encryption to keep you and your customers safe.

World-Class Technical Support

We're geeks at heart, so you might not be surprised that IPv6 and HTTP/2 come as standard. What you might not expect is that our support team is on hand to answer your questions 365 days a year.

'Fast currency API and always great support'

Get Free Trial API Key

We had intermittent failures with our previous currency exchange API provider. We decided to change to fastFOREX. The setup was easy, and we always get fast response times. That’s all we need.
