GET
/v1/tiktok/post/transcript

Returns the spoken text of a TikTok video from its captions, with an option to fall back to AI transcription when no captions exist.

Use it when you need what was said rather than the numbers; post gives you the video's caption and metrics but no transcript.

200 credits per call.

Re-running the exact same call within 6h is free.

Query Parameters

url*string

Full URL of the TikTok video

language?string

Language of the transcript. 2 letter language code, ie 'en', 'es', 'fr', 'de', 'it', 'ja', 'ko', 'zh'

use_ai_as_fallback?string

Set to 'true' to fall back to AI transcription when the video has no captions.

moments?string

Optional CSV of moment kinds to find: brand, sponsor_read, product_demo, call_to_action. Returns data.moments = [{ kind, start_ms, end_ms, quote }] when the transcript has timestamps. Price of the extra step is an owner decision; today it does not add credits.

brand?string

Optional, with moments=. The company or product to look for, so a namesake is not counted.

q?string

Optional question about the video, up to 300 characters, for example q=what discount code do they give. Returns data.moments = [{ kind: "answers_query", start_ms, end_ms, quote }] for each stretch of about six transcript lines that states the answer: a stretch that only shares the topic is left out, and a question the video never answers returns an empty list. The quote is one line copied from the transcript and the times come from the segments. Send moments= or q=, not both. If the step cannot run, the transcript is returned without data.moments and data._warnings carries moments_unavailable. Today it does not add credits.

Post › Comments GET

Returns a page of comments on one TikTok video, each with the commenter's username, comment text, like count, reply count, and timestamp. Use it to read a video's comment section; to expand one thread, take a comment's id and call video/comment/replies. **Metered: 20–140 credits.** We reserve the ceiling when the call starts and charge what it actually used when it finishes. Re-running the exact same call within 6h is free. Paginates by `cursor` — see [Pagination](/docs/pagination).

Post GET

Returns one TikTok video in full: caption, engagement counts, author, sound, video metadata, and any on-screen text the creator typed with TikTok's text tool (post.ext.on_screen_texts). Use it when you already have a video URL and want that single video's numbers, rather than a list from profile/videos or search. **20 credits** per call. Re-running the exact same call within 6h is free.
