How to extract CurveStartPoint or CurveEndPoint in CPlane Coordinate System?

Hello,
I am completely new to Rhino Python.
I wish to extract coordinates in CPlane system of start and end points of a Curve.
But the CurveStartPoint and CurveEndPoint functions spit out in World system.
Is there a way to get around it without rotating and shifting the coordinate system using the gumball?
Thanks George
