GET

Clip Transcript

Get native captions from a Twitch clip. Enable use_ai_as_fallback for AI when captions are unavailable.

Credit cost	Default: 1 credit when no rule matches. 0 credits when response field transcript is empty or absent. 1 credit when response field native is exactly true. 10 credits per started minute (duration from durationSeconds or duration_seconds) when request parameter allow_long_transcription is true. Native captions or AI up to 2 minutes: 1 credit. Paid AI mode: 10 credits/minute, rounded up, even for short videos. No transcript: 0 credits. Returned native captions cost 1 credit, even for long videos with the paid flag. By default, successful AI up to 120 seconds costs a flat 1 credit per request; over 120 seconds requires allow_long_transcription=true, which bills ALL successful AI at 10 credits per started minute, including short videos; empty AI results and errors cost 0 credits; no transcript: 0 credits How charges are determined Cost is decided per call, not per endpoint: the same operation can cost different amounts depending on what it returns. A call that fails costs 0 credits. A result served from cache costs 0 credits. `default` is the cost when no rule matches. Rules are evaluated in order and the first whose conditions all hold wins. A `when` condition is one of: `param` (the request parameter is true), `outcome` (the classifier's outcome), `empty` / `nonEmpty` (a response field is empty and absent, or a non-empty array or string), `flag` (a response field is exactly true). A cost of `{ perStartedMinute: n, of: [fields] }` is n x max(1, ceil(seconds / 60)), so even a short result bills at least one minute.
