Why the thread matters more than the post
On Reddit the useful part is usually below the post: the correction, the first-hand experience, the disagreement. An API that bills per comment or per page of comments makes whole-thread analysis expensive. Here the whole thread is one flat-priced request.
Datasets for models
Collect question and answer pairs or multi-turn discussions with their structure intact.
Support and feedback triage
Follow threads about your product and read every reply, including the ones buried deep.

Comments API questions
How many comments come back in one request?
Up to 200. The default is 50, and you raise it with commentLimit. The request costs the same either way.
Do I get replies, or only top-level comments?
A post request includes the comment tree with replies by default. Set includeChildren=false if you only want the post itself.
Can I fetch a single comment?
Yes. GET /reddit/v1/comments/{id} returns one comment by its id. The t1_ prefix is optional.
Can I look up a post without knowing its subreddit?
Yes. GET /reddit/v1/posts/{id} needs only the post id. The t3_ prefix is optional.
