Get a Reddit post's comments by post ID API

One call returns all comments on a single Reddit post, organized as a tree structure. Each comment item includes the comment text, author, score, and nested replies. The answer is a single post with its full comment forest; there is no pagination.

2 live routes on Reddit, from $0.00015 per call. Every route below answered our last live test on 2026-10-06; the gateway re-tests them daily.
