Integrate the Qwen Image 2.0 Pro API

Every request is asynchronous: submit the task, keep the task ID, then poll for the result. The body below uses the model's default settings.

1. 1

   Get a Qwen Image 2.0 Pro API key

   Sign in and create a key in the dashboard. Set WIZZX_API_KEY in your server environment; never expose it in browser code.

2. 2

   Submit a task

   Send a POST request to the model endpoint. A successful submission returns data.task_id; keep that ID before polling. Submission is not generation completion.

3. 3

   Retrieve the result

   Replace YOUR_TASK_ID with the returned ID and query /api/v1/task/status. Wait for SUCCEEDED and read the output URLs. Stop on FAILED or REVIEW_REQUIRED; do not automatically resubmit an uncertain task.
