cURL

curl -X POST https://crazyrouter.com/mj/submit/imagine \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "botType": "MID_JOURNEY",
    "prompt": "a cat in the style of the reference image --v 6",
    "base64Array": [
      "data:image/png;base64,iVBORw0KGgoAAAANSUhEUg..."
    ]
  }'

Using Niji Journey

Set botType to NIJI_JOURNEY to use the Niji model for anime-style images:

{
  "botType": "NIJI_JOURNEY",
  "prompt": "a cute anime girl with blue hair, cherry blossoms --niji 6"
}

After successful submission, a task ID is returned. Use the Query Task Status endpoint to get the generation result.

Images in base64Array increase the request payload size. It is recommended to keep each image under 4MB.
