Use this endpoint after you create a Seedream image with POST /v1/images/generations and async: true. The create request returns data.task_id, and this endpoint returns the task state plus final image data when the task succeeds.

​
Poll a Seedream image task

1

Create the task

Send POST /v1/images/generations with async: true, then store data.task_id.
2

Poll the task

Call this endpoint with the stored task ID until data.status is success or failure.
3

Read the image data

When data.status is success, read the first item in data.data. Seedream async results can include url, b64_json, and revised_prompt.

​
Status values

  • pending: The task is queued or generating.
  • success: The task finished and data.data contains the generated image data.
  • failure: The task failed. Check data.fail_reason when it is returned.
