hi @nholmquist you can use the the “List folder Children” route you can get the id for the head version (see line 13 on attached screenshot) which you could then use in the subsequent "List comments" route to be returned the comments for that asset.
This will include any of the comments related to the most recent asset in a Version Stack, which is always the latest version unless someone were to reorder the stack. Getting comments on different versions of the version stack is not yet supported.
