API referenceVideos

Get comment replies

GET /v1/videos/{platform}/{id}/comments/{comment_id}/replies

A page of the replies to one comment, in the order the platform ranks them. comment_id is a comment's id from GET /v1/videos/{platform}/{id}/comments: read that page first, since a comment we have not listed for the video is comment_not_found (404) and nothing is charged. Each reply is a comment item with parent_id set to comment_id, and like comments it carries no author information at all. A comment with no replies answers an empty items and a null next_cursor. Replies are purged after 90 days, like comments. TikTok, Instagram and Facebook; other platforms are unsupported_platform. On Facebook, one level of replies is returned (replies to a reply are not walked), and a comment the platform no longer lists is comment_not_found with nothing charged. On Instagram, reply_count on a comment is often 0 even when it has replies, so a thread can be worth asking for regardless.

Price

3 credits per page, the same when the replies are already stored.

Supports estimate=true: the reply is the price in Credits and whether it would be cached, with no Run created and nothing charged.

A cached result costs the same as a fresh one; cached says which you got.

Parameters

NameInTypeRequiredDefaultDescription
platformpathstring one of tiktok, instagram, facebookRequired—Platform the subject lives on.
idpathstring Required—Platform video id.
comment_idpathstring Required—The comment's id, as the comments page returned it.
limitqueryinteger min 1; max 100Optional25Items per page.
cursorquerystring Optional—Opaque next_cursor from the previous page.
waitqueryinteger min 0; max 120Optional30Seconds to hold the response open before handing back a running Run to poll. Default 30, max 120. A POST may send it in the body instead; given in both places with different values it is a 400.
estimatequeryboolean Optional—true returns { estimate_credits, cached } computed from what is already stored, and creates no Run. Nothing is charged. When a source the call would read is unavailable and the answer is not served from cache, the estimate adds unavailable, the { platform, capability } parts it cannot reach, or answers 503 source_unavailable when it can reach none. Only true or false; anything else is a 400. A POST may send it in the body instead; given in both places with different values it is a 400.
Idempotency-Keyheaderstring Optional—1-255 printable ASCII characters. Replaying this key with the same payload returns the original Run (202 while it is still running); a different payload, or a different operation, is a 409 idempotency_conflict.
