How can I access the measurements displayed with the Measure Tool in Blender 2.80 from Python? I'm not seeing it anywhere in the documentation, hoping I'm just blind. Thanks.

All credit for this answer goes to the discussion here.

The data is stored in the grease pencil annotations:

bpy.data.grease_pencils["Annotations"].layers['RulerData3D']

Specifically, to get a list of all length measurements currently in the scene:

lengths = list((s.points[0].co - s.points[-1].co).length for s in bpy.data.grease_pencils["Annotations"].layers['RulerData3D'].frames[0].strokes)
