Request body
11 properties · 1 required · 1 $defs| property | type | description | constraints |
|---|---|---|---|
| prompt* | string | The text prompt to guide image generation. | |
| image_size | ImageSize | enum | The size of the generated image. | default: "square_hd" |
| enable_output_safety_checker | boolean | If set to true, output video will be checked for safety after generation. | default: false |
| image_format | enum | The format of the output image. | png | jpeg · default: "jpeg" |
