Does anybody use Test Engine Rest API

I'm not sure about Test Engine REST API - I didn't realise it can access applications running on the computer and simulate user actions. My understanding is that REST APIs are generally used for sending requests to and receiving responses from a web server. Concepts of Test Engine REST API are good!

From what I've read about the Test Engine REST API, I prefer to use TestComplete, as it gives me more control. However, I'm also unsure how stable the Test Engine REST API is. I agree that support may be limited, and it's something SmartBear hasn't advertised much.
