Retrieve image task

Look up a qwen/qwen-image-3.0 generation task; the response uses Alibaba Model Studio's own shape. DashScope clients build this address themselves, so retrieval keeps working once base_url points here.

Authorization

header

AuthorizationstringRequired

Bearer <your Amux key> Your Amux API key.

Request

idstringRequired

The task ID returned when you submitted.

Response

200response

Always 200 whether or not it is done; the state is in task_status.

404response

No such task, or it does not belong to this workspace. Both answer the same way, so that probing IDs across workspaces reveals nothing.

It reads the same task as the Amux endpoint#

One task, two renderings — not two stores. New integrations should prefer GET /v1/tasks/{id}, which also carries usage and cost; the DashScope shape has no fields for them.

One behavioural difference from upstream#

Upstream forgets a task after 24 hours and answers UNKNOWN. Our task rows are never deleted and always return the real terminal state, so a client that treats UNKNOWN as its give-up condition will never take that branch here.

Artifact URLs are ours#

choices[].message.content[].image points at our storage rather than upstream's signed temporary URL. It is cleaned up periodically, so download anything you need to keep.

Errors#

Errors come back in Alibaba Model Studio's shape. The type values and their retry semantics are in Errors and retries.
