A sample to get animate points une roto node :
views = nuke.views()
print views
rotoNode = nuke.selectedNode()
print rotoNode
rootLayer = rotoNode['curves'].rootLayer
print rootLayer
for shape in rootLayer:
print shape
for point in shape:
print point
view = views[0]
print point.center
print point.leftTangent
print point.rightTangent
listControlPointKeyTimes = point.center.getControlPointKeyTimes()
print listControlPointKeyTimes
for keyTime in listControlPointKeyTimes:
print point.center.getPosition( keyTime, view)
print point.leftTangent.getPosition( keyTime, view)
print point.rightTangent.getPosition( keyTime, view)
print point.featherCenter.getPosition( keyTime, view)
print point.featherLeftTangent.getPosition( keyTime, view)
print point.featherRightTangent.getPosition( keyTime, view)
