Use the same project, location, publisher and model as creation, and pass back the complete operationName unchanged.

Polling and status

Replace <OPERATION_NAME> with the full name from creation and poll every 10 to 15 seconds:

curl "https://api.aiohub.org/v1/projects/<PROJECT>/locations/<LOCATION>/publishers/bytedance/models/doubao-seedance-2-5-260628:fetchPredictOperation" \
  -H "Authorization: Bearer <AIOHUB_API_KEY>" \
  -H "Content-Type: application/json" \
  -d '{"operationName": "<OPERATION_NAME>"}'

Response	Action
`done: false`	Keep polling
`done: true` with `response`	Download the video
`done: true` with `error`	Stop polling and read `error.message`

done: true means the operation ended, not necessarily that it succeeded.

Read a successful result

Key fields in a successful response:

{
  "name": "projects/<PROJECT>/locations/<LOCATION>/publishers/bytedance/models/doubao-seedance-2-5-260628/operations/task_example",
  "done": true,
  "response": {
    "videos": [
      {
        "gcsUri": "https://api.aiohub.org/v1/videos/task_example/content",
        "mimeType": "video/mp4"
      }
    ]
  }
}

response.videos[0].gcsUri is an AIOHub HTTPS URL, not a gs:// object. Download with an HTTP client; Google Cloud Storage is not required. After success, download the video.

Failures and retries

After a polling disconnect, keep polling the same name rather than calling predictLongRunning again. Correct fields before retrying a 400. If a terminal operation has error, do not read the success response fields. Files remain for 72 hours and task records for 7 days. After a 429 or temporary service error, wait before retrying the read; do not create another task. If a task is missing, check the identifier and the account that owns the API key.
