Video transcript API
7 endpoints on 7 platforms return the same Transcript object. The words spoken in a video, as text. Every call costs $0.0020; a failed call is free.
Video transcript on each platform
One row per endpoint: what it is called, how much comes back in a call, and what a call costs.
The Transcript object
Every endpoint above returns these fields, with the same names and types.
post_idtextID of the post it belongs tolangtextLanguage codetexttextThe whole textsegments[].startnumberStart, in secondssegments[].endnumberEnd, in secondssegments[].texttextText of the segmentWhich platform fills which field
A field an endpoint cannot give is listed in meta.unavailable on every answer, so a gap is never a surprise.
The same call on two platforms
Same parameter names, same paging, same answer. Only the path changes.

}TikTok video transcript: From a response recorded 2026-10-12 18:47 UTC. Names, text and IDs are examples, and so are the links: none is the recorded one (the page shows no one's personal data); the figures are as recorded. Long lists are cut. The request ID, cursor and balance are made up.

Questions about the Video transcript API
Short answers. Each endpoint's page has its own limits and examples.
TikTok video transcript API →How much does it cost?
$0.0020 a call on TikTok, YouTube, Instagram, X (Twitter), Reddit, LinkedIn, Meta Ad Library. You are charged when data comes back; a failed call costs nothing. No subscription, no monthly minimum.
Does every platform fill every field?
No. 4 of the 6 fields are missing on at least one platform; the table on this page says which. A field an endpoint cannot give is named in meta.unavailable on every answer, never filled with a guess.
Do I need an account on the platform?
No. One DataXAPI key reads all 7 platforms. No platform account and no cookie.
Other data types
The same idea everywhere: one action, every platform that has it.
Start with one key.
207 endpoints on 21 platforms, from $0.0003 a call. Errors and timeouts are not charged.
