TikTok Comments API
TikTok comments — clean schema plus authorName, stable authorId/authorSecUid and commentLanguage for listening loops. Unresolvable videos are 404 at 0 credits.
GET request to /v1/tiktok/comments that responds with clean JSON and costs 2 credits. Pass cache=true for a free 24h cache hit; default is always fresh. Start with 100 free credits — no credit card.What is the TikTok Comments API?
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 the native comment path is blocked, the first page may come from the extended actor: degraded=true with degradedReason=extended, totalComments stays on the envelope, and hasMore is false (the actor cannot page). Flat 2 credits per successful call. Need replies? Use TikTok Comment Replies with the parent comment id.
What you get
- author handle + authorName display name
- Stable authorId + authorSecUid (not just username)
- commentLanguage for market listening
- replyCount when TikTok exposes it
- Like count, publish time, totalComments + cursor pagination
- Unresolvable video → 404 at 0 credits
- limit up to 500 — flat 2 credits per call

Top-level fields
platformPlatform identifier for this response (matches the endpoint's platform).urlCanonical URL of the item.totalCommentsVideo-level comment count when TikTok exposes one.

Omitted on a native page only when TikTok sent no total.totalReturnedNumber of items returned in this response.nextCursorNumeric offset to pass back as cursor. Null means the end of the comments.hasMoreBoolean on every path. true when nextCursor is a resume offset; false when nextCursor is null (end of the thread, or the extended actor which cannot page). Never null.
Comments
Each item in comments contains:
idId of this comments item.textText content.authorAuthor name or handle.authorAvatarUrlProfile picture URL of the person who wrote the comment.likeCountLike count as an integer. Compact UI labels ("727K") are expanded here; see likeCountText for the original string.publishedAtPublish date (ISO 8601) when the platform exposes an absolute timestamp.authorIdAuthor id. Example: "6958917445306926086".commentLanguageComment language. Example: "en".replyCountHow many replies this comment has. Use Comment Replies with this comment's id to fetch them.authorSecUidPrimary artist / sound-owner secUid when TikTok exposes one.authorNameName of the author.

Frequently asked questions
What does the TikTok Comments API do?+
The TikTok Comments API lets you pull comments with author, text, likes, and replies from a public TikTok video using one GET request to /v1/tiktok/comments. It returns clean JSON — no OAuth or infrastructure setup required.
How many credits does the TikTok Comments API cost?+
Each successful call costs 2 credits. Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d. Failed or empty results are never charged.
Do I need a TikTok API key or OAuth?+
No. A single Captapi key works across every platform Captapi supports — YouTube, TikTok, Instagram, Facebook, Twitter/X, Reddit, Threads, Bluesky, Pinterest, LinkedIn, Rumble, Spotify, Kwai, and more. We handle proxies, rate limits, retries, and authentication for you.
What happens when the video does not exist?+
HTTP 404 at 0 credits — the same answer /tiktok/video-details already gives for that URL. Comments never returns 200 with a synthesised row (an empty-text comment and totalReturned: 1). Zero is a number people act on; a miss is not a thread.
What does degraded / degradedReason mean?+
When TikTok's native comment API is blocked, the first page may come from the extended actor. Those responses set degraded=true and degradedReason=extended. hasMore is still a boolean (false — the actor cannot page) and totalComments stays on the envelope. Retry the call if you need the native cursor.
Is the TikTok Comments API suitable for production use?+
Yes. It is a stable REST endpoint with predictable JSON and automatic retries. Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d. Use it for analytics, monitoring, and content automation.
