Gets all top level comments for a Rumble video by URL. Returns comment text, author, createdAt, createdAtText, likeCount, dislikeCount, and replyCount when comment bodies are public. If Rumble requires sign-in to view the comments, this endpoint returns HTTP 403 with error forbidden and does not charge credits. This is different from a public video with no comments, which returns a successful empty comments array.

Sign-in-required response example:

{
  "success": false,
  "credits_remaining": 100,
  "credits_charged": 0,
  "error": "forbidden",
  "errorStatus": 403,
  "message": "Rumble requires you to sign in to view this video's comments"
}
