Download finished Sora video content
curl --request GET \
  --url https://api.cometapi.com/v1/videos/{video_id}/content \
  --header 'Authorization: Bearer <token>'
"<string>"
Use this endpoint to download the finished Sora output after the job reaches completed. Until then, it returns an error instead of a video file.

​
Before you download

  • Wait until Retrieve Video reports status: completed
  • Pass the video_id from the create or remix step
  • Store the file in your own bucket or CDN if you need it to outlive the provider’s temporary delivery window

​
Download flow

1

Create or remix the video

Start with Create Video or Remix Video.
2

Poll for completion

Use Retrieve Video until the job reaches completed.
3

Fetch the binary file

Call this endpoint to download the MP4 or another supported asset variant.

​
Temporary delivery window

OpenAI’s Videos API uses the same final download step. During live validation on 2026-03-12, calling this endpoint before completion returned an invalid_request_error JSON response, which is the behavior you should expect while a render is still running.
