Knife tool with bmesh API I need to find the intersection curve between two (open) meshes, and I can do that interactively with the knife tool. In search for a way to do it from a script, I came across the following highly relevant question:
Using knife_tool from python api

There is one answer, which simply refers to the BMesh API. However, I find no immediate candidate for the knife_tool from bpy.ops.mesh in bmesh.ops.mesh. Is there a way to script mesh intersection cutting from bmesh, or at all?

The attached screendump illustrates a cut in the cylinder mesh from the intersecting sphere mesh. I obtain it interactively with the cylinder mesh edges selected, then by Ctrl+F and choosing "Intersect (Knife)".
Could be this?

# Select all vertices in Edit Mode
bpy.ops.mesh.select_all(action='SELECT')

# Do intersect
bpy.ops.mesh.intersect()
bpy.ops.mesh.intersect(mode='SELECT')
