Routes to Alibaba Cloud's image generation service. Supports both synchronous and async task modes. Does not support SSE streaming.

Supported models

Synchronous mode

curl -X POST https://51kik.com/v1/image/v1/generations \
  -H 'Authorization: Bearer sk-xxxxxxxx' \
  -H 'Content-Type: application/json' \
  -d '{
    "model": "wanx-v1",
    "prompt": "ancient chinese ink painting of mountains and clouds",
    "upstream_options": { "n": 1, "resolution": "1024*1024", "watermark": false, "prompt_extend": true }
  }'

Image-to-image

curl -X POST https://51kik.com/v1/image/v1/generations \
  -H 'Authorization: Bearer sk-xxxxxxxx' \
  -H 'Content-Type: application/json' \
  -d '{
    "model": "qwen-image-edit",
    "prompt": "convert to oil painting style",
    "image": "https://example.com/source.jpg",
    "upstream_options": { "n": 1, "aspect_ratio": "16:9", "result_type": "image" }
  }'

Async task

curl -X POST https://51kik.com/v1/image/v1/generations \
  -H 'Authorization: Bearer sk-xxxxxxxx' \
  -H 'Content-Type: application/json' \
  -d '{
    "model": "wanx-v1",
    "prompt": "a panoramic mountain landscape",
    "task": true,
    "upstream_options": { "resolution": "2048*1024", "n": 4 }
  }'

Response contains only task_id; poll for results:

curl https://51kik.com/v1/image/v1/tasks/abc123-task-id \
  -H 'Authorization: Bearer sk-xxxxxxxx'

Streaming limitation

Bailian does not support SSE streaming. Passing stream: true returns Bailian image generation does not support streaming.

Common upstream_options

Parameter	Description
`n`	Number of images
`resolution`	Resolution, e.g. `1024*1024`
`aspect_ratio`	Aspect ratio, e.g. `16:9`
`watermark`	Toggle watermark
`prompt_extend`	Auto-expand prompt
`negative_prompt`	Negative prompt
`seed`	Random seed
`result_type`	Output type: `image` / `url`

Don't pass both task: true and stream: true simultaneously — behavior is undefined.
