Welcome to COS

COS is a collection of REST APIs which enable unique financial products to be designed and managed. COS was designed to be an API driven banking core from the ground up, with no legacy systems getting in the way. We give you the same tools to build your product that we use internally.

We offer a full sandbox to explore the API. The sandbox is a completely isolated environment, so feel free to experiment. When you're ready to move to production, we will provision you production credentials and give you access to the live environment.
