## Input Parameters

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `prompt` | string | Yes | - | Text description of the image to generate. |
| `generation_model` | enum | No | qwen-image-plus | DashScope model variant. Rolling: qwen-image-plus, qwen-image-max. Dated snapshots for pinning: qwen-image-plus-2026-01-09, qwen-image-max-2025-12-30. Legacy: qwen-image. Ignored when lora_weights is set (LoRA path uses Replicate). (Options: qwen-image-plus, qwen-image-plus-2026-01-09, qwen-image-max, qwen-image-max-2025-12-30, qwen-image) |
| `aspect_ratio` | enum | No | 1:1 | Image aspect ratio. The qwen-image-plus / qwen-image-max series ship five recommended aspect ratios; 21:9 is only available on the LoRA Replicate path. (Options: 1:1, 16:9, 9:16, 4:3, 3:4...) |
| `negative_prompt` | string | No | - | What to avoid in the output (max 500 characters). |
| `prompt_extend` | boolean | No | true | Enable smart prompt rewriting on the DashScope path. The model expands your prompt for richer detail. Default true. |
| `watermark` | boolean | No | false | Adds a "Qwen-Image" watermark to the bottom-right corner. |
| `num_inference_steps` | integer | No | 35 | LoRA path only — number of inference steps (28-50). (min: 28, max: 50) |
| `guidance` | number | No | 3 | LoRA path only — guidance scale (2-4). (min: 2, max: 4) |
| `go_fast` | boolean | No | false | LoRA path only — enable faster generation. |
| `numberOfImages` | integer | No | 1 | Number of images to generate. The DashScope path (qwen-image-plus / qwen-image-max) is fixed at 1 per upstream contract; the LoRA Replicate path supports 1-4. (min: 1, max: 4) |
| `seed` | integer | No | - | Random seed for reproducibility (0–2147483647). (min: 0, max: 2147483647) |
| `lora_weights` | string | No | - | URL or HuggingFace path to a Qwen Image LoRA. Supplying this routes the request through the Replicate LoRA remix variant and unlocks numberOfImages > 1 + LoRA-specific params. |
| `lora_scale` | number | No | 1 | Strength of the LoRA effect (typical 0–2). (min: 0, max: 2) |

  "status": "completed",
  "output": {
    "images": ["https://temp.pixeldojo.ai/..."]
  },

}
```

## Python Example

```python
import requests
import time

API_KEY = "YOUR_API_KEY"

# Submit job
response = requests.post(
    "https://pixeldojo.ai/api/v1/models/qwen-image-max/run",
    headers={
        "Authorization": f"Bearer {API_KEY}",
        "Content-Type": "application/json"
    },
    json={
        "prompt": "A beautiful mountain landscape at golden hour, photorealistic",
        "aspect_ratio": "1:1"
    }
)

job = response.json()
job_id = job["jobId"]

# Poll for completion
while True:
    status_response = requests.get(
        f"https://pixeldojo.ai/api/v1/jobs/{'{job_id}'}",
        headers={"Authorization": f"Bearer {API_KEY}"}
    )
    status = status_response.json()
    
    if status["status"] == "completed":
        print("Output:", status["output"])
        break
    elif status["status"] == "failed":
        print("Error:", status.get("error"))
        break
    
    time.sleep(2)
```

## JavaScript Example

```javascript
const API_KEY = 'YOUR_API_KEY';

// Submit job
const submitResponse = await fetch('https://pixeldojo.ai/api/v1/models/qwen-image-max/run', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${API_KEY}`,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    prompt: 'A beautiful mountain landscape at golden hour, photorealistic',
    aspect_ratio: '1:1'
  })
});

const job = await submitResponse.json();

// Poll for completion
const pollForResult = async (jobId) => {
  while (true) {
    const statusResponse = await fetch(`https://pixeldojo.ai/api/v1/jobs/${jobId}`, {
      headers: { 'Authorization': `Bearer ${API_KEY}` }
    });
    const status = await statusResponse.json();
    
    if (status.status === 'completed') return status.output;
    if (status.status === 'failed') throw new Error(status.error);
    
    await new Promise(r => setTimeout(r, 2000));
  }
};

const output = await pollForResult(job.jobId);
console.log('Output:', output);
```
