Qwen - Image to Image

Image generation by Qwen's advanced AI model ## Query Task Status After submitting a task, use the unified query endpoint to check progress and retrieve results: <Card title="Get Task Details" icon="lucide-search" href="/market/common/get-task-detail"> Learn how to query task status and retrieve generation results </Card> For production use, we recommend using the `callBackUrl` parameter to receive automatic notifications when generation completes, rather than polling the status endpoint. ## Related Resources <CardGroup cols={2}> <Card title="Market Overview" icon="lucide-store" href="/market/

Name	Type	Required	Description
`prompt`	string	required	The prompt to generate the image with (Max length: 5000 characters)
