Get All Keyframes/Events in an animation

I'm trying to detect when objects move a large distance in an animation clip, but from the documentation I can't see how to access the keyframes or events in an animation clip.

There's a function for getting animation curves in the editor, but I need to do it at runtime. I could re-import all my animations and do the processing in the editor but that seems error-prone.

Is there a function I've missed somewhere?

Ideally I just want a list of frame or time indices and positions for each curve
