I want to obtain the position of a point on a line where Y has an arbitrary value.
For example, I want to obtain the position of the point on the arc (the red dot) when Y equals 4.

    Here is something crude to get you started:

    edge = ExtAPI.SelectionManager.CurrentSelection.Entities[0]
tolerance = .01 # 1%
y_value = .01
points = [edge.Points[3*i:3*i+3] for i in range(int(len(edge.Points)/3))]
ps = [p for p in points if p[1]>y_value*(1-tolerance) and p[1]<y_value*(1+tolerance)]

    To get more refined, I think you would want to find the two points closest to the Y-line and then do an interpolation to get the intersection.
