The batch endpoints allow you to process multiple YouTube videos in a single request. This is useful for analyzing entire playlists or channels, or for processing a list of videos. Batch operations are asynchronous and return a job ID that can be used to check the results.
This feature is available only on paid plans.

​
Supported Source Types

All batch endpoints support the following source types:
  • List of video URLs or IDs
  • Playlist URL or ID
  • Channel URL, handle, or ID

Batch Job Status

The batch job can be in one of the following states:
StatusDescription
queuedThe job is in the queue waiting to be processed
activeThe job is currently being processed
completedThe job has finished processing all videos
failedThe job failed due to an error
Batch jobs are processed asynchronously and may take some time to complete, especially for large playlists or channels. You should poll the job status endpoint until the status is either “completed” or “failed”.

​
Pricing

  • 1 request to start a batch job = 1 credit
  • 1 video / transcript in a batch = 1 credit
For example, if you start a batch job with 10 videos, you will be charged 11 credits: 1 for the request and 10 for the videos.
