Pixera can be downloaded as a demo version and the api is working on that. So I tried it for a longer time yesterday and found a JSON client for API Testing which works very well. Is quit simple, I am using the HTTP Port on 8080 (own choice) and also have activated the Port 1400 for JSON TCP. You can use two API Ports at the same time and two Output Ports for sending something back from the timeline. They have also a JSON DL with delimiter Px0X ehich you can use. But for now the HTTP work. The thing is, you have to send the command as RAW. In the Software I just fill out the body part with the command and send it as RAW and get a RAW back from the API.
But if you have some time, it would be also nice to visit your place for a nice talk 🙂
