## Example - Text-to-Image

```bash theme={null}
curl -X POST https://api.unifically.com/v1/tasks \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "model": "bytedance/seedream-5.0-lite",
    "input": {
      "prompt": "A cyberpunk city at sunset, neon lights reflecting on wet streets",
      "resolution": "3K"
    }
  }'
```

## Example - Image-to-Image

```bash theme={null}
curl -X POST https://api.unifically.com/v1/tasks \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "model": "bytedance/seedream-5.0-lite",
    "input": {
      "prompt": "Place the animal inside the vintage car",
      "image_urls": [
        "https://example.com/animal.jpg",
        "https://example.com/car.jpg"
      ],
      "resolution": "2K"
    }
  }'
```

<Note>
  `max_sequential_images` is the maximum number of sequential images the model may generate—not a fixed batch size. The model chooses how many to produce (from 1 up to that limit). Omit the parameter or set `max_sequential_images` to `1` for a single image. Sequential images are billed per image.
</Note>

## Response

```json theme={null}
{
  "code": 200,
  "success": true,
  "data": {
    "task_id": "9d489f02-316f-4386-8188-dc19540d56f5",
    "status": "completed",
    "output": {
      "image_urls": [
        "https://files.unifically.com/image/92116e95-8dd4-4cbb-b53f-ee643e1045d8.jpg"
      ]
    }
  }
}
```

The number of URLs in `image_urls` reflects how many sequential images the model generated (up to your `max_sequential_images` ceiling).
