Authorizations

Authorization

string

header

required

Pass Authorization: Bearer <token> in the request header.

Body

application/json

model

enum<string>

required

Model name. Available values: qwen-image-2.0-pro, qwen-image-3.0-pro.

Available options:

qwen-image-2.0-pro,

qwen-image-3.0-pro

input

object

required

response_format

enum<string>

default:url

Response format. url returns an image download link; b64_json returns Base64-encoded image data. Default is url.

Available options:

url,

b64_json

integer

Number of output images. Default is 1. For the qwen-image-2.0 and qwen-image-3.0 series, you can generate 1-6 images.

Required range: 1 <= x <= 6

size

string

default:1024*1024

Output image resolution in width*height format. For the qwen-image-2.0 and qwen-image-3.0 series, total output pixels must be between 512*512 and 2048*2048, and the default resolution is 1024*1024. Recommended resolutions: 2688*1536 (16:9), 1536*2688 (9:16), 1024*1024 (1:1, default), 2368*1728 (4:3), and 1728*2368 (3:4).

negative_prompt

string

Negative prompt used to describe content that should not appear in the image and to constrain the image. Chinese and English are supported. Maximum length is 500 characters; extra content is automatically truncated. Example: low resolution, low quality, malformed limbs, malformed fingers, oversaturated image, wax figure appearance, no facial details, overly smooth, AI-like image, chaotic composition, blurry or distorted text.

prompt_extend

boolean

Whether to enable smart prompt rewriting. When enabled, the model optimizes and polishes the positive prompt. This feature does not modify the negative prompt. true (default): enabled, recommended for more diverse content. false: disabled, recommended for more controllable details.

watermark

boolean

default:false

Whether to add a watermark in the lower-right corner of the image. Default is false. For qwen-image-2.0-pro, the watermark is "Qwen-Image"; for qwen-image-3.0-pro, the watermark is "AI生成".

seed

integer<int64>

Random seed. Range [0, 2147483647]. Using the same seed value can make generated content relatively stable. If omitted, the algorithm automatically uses a random seed. Note: generation is probabilistic, so the same seed cannot guarantee identical results every time.

Required range: x >= 0

Response

Success. Returns the image generation result.

created

integer<int64>

Response generation timestamp.

data

object[]

List of generated image results.

metadata

object

Pass-through raw response metadata from the upstream provider.
