Power off tv comand line

Hi everyone.
please help, I need to turn off the TV ( UE55AU9005KXXC) or put it into sleep mode from the command line.
type: curl -X POST -i ‘http://192.168.110.50:8001/api/v2/applications/111299001912
I do not know how to do it
I could only run YouTube and other applications.
Thanks

How can I wrap it in the format ( curl -X POST -i ‘http://192.168.110.50:8001/xxxxxxxx’) ? ty
