You can search for some drivers to use as examples. A lot of it really depends on how complicated the API is though. For example, I have a BUNCH of API drivers now for everything from Cloud API weather stations, Local to network aquarium controllers, the Blink API, and most recently working on my local network Unifi API.
You can take a look at a couple of those drivers to get a basic idea. Otherwise, asking like this is also a good way to get people that might be able to make one for you interested. I have made a couple drivers for other APIs that I do not personally have devices for (as an example).
My recommendation is that if you are interested in learning, look at some examples to create your own because it can come in handy as you add more to your system over time. If you decide not to, let me know and I will try to help make a driver for you.
Their API does not look too bad at all.
