Parameters
The YouTube video — its 11-character id (`dQw4w9WgXcQ`) or the full URL.
Bypass cached data and force a live fetch for this one call. Use it for daily monitoring or any figure you are tracking over time. Accepts `true`, `1`, `false` or `0`; anything else returns 400 `invalid_fresh`. Defaults to false and costs exactly the same as a cached call.
One of: true, 1, false, 0
Example request
Live call. Successful calls are charged; failed and empty results are not.

}Limits
- Maximum per call: 1 transcripts.
- Minimum per call: 1 transcript — a target with less data returns fewer transcripts, and an empty result is still a successful call.
- Each call fetches a full page of up to 1 and costs the same either way. Pass limit to receive fewer than that in the response.
- This endpoint returns a single record per call and is not paginated.
