Yes. Select generate and provide a prompt describing the subject, environment, lighting, composition, and style to start text-to-image generation. If you want to match an existing product or brand visual, you can also add image references; choose the aspect ratio based on the actual use case, such as a cover, banner, or vertical content.

Use edit, provide the images to process through image_urls, and explain the relationship between the assets in the prompt. For example, keep the product's shape and replace the environment with a morning-lit wooden table scene. When blending multiple images, clearly specify the roles of the main subject image and background image rather than writing only vague compositing requirements.

When creating consecutive variants, it is recommended to use the image selected in the previous round again as a reference and clearly state what should be retained and changed in the current round. This makes the editing baseline explicit without relying on implicit history; for character or product series, continue using stable descriptions of identity traits to reduce unnecessary changes.

The endpoint returns an image URL along with task_id and trace_id for linking tasks and results. For batch asset workflows, use async and callback_url to handle completion notifications, then send images through selection, review, and archiving steps; before official release, you should still verify subject details and text.
