TikTok Comments API
TikTok comments — clean schema plus authorName, stable authorId/authorSecUid and commentLanguage for listening loops.
Paste a public TikTok video URL and get comments as clean JSON (not TikTok's 40+ junk user fields). Each comment keeps username (author) + display name (authorName) + avatar, and adds stable authorId (uid) and authorSecUid for repeat-commenter detection, plus commentLanguage for market listening without a separate language detector. replyCount when TikTok exposes it. totalComments + cursor pagination (nextCursor/hasMore — hasMore is always a boolean; a null nextCursor means the end of the comments). An unresolvable URL is 404 at 0 credits — never a 200 with a synthesised row. Same rule as Post Analytics and as /tiktok/video-details on the same URL. When TikTok blocks the comment fetch the call is 503 UPSTREAM_UNAVAILABLE at 0 credits — retry shortly. Flat 2 credits per successful call. Need replies? Use TikTok Comment Replies with the parent comment id.
