## Usage

### Generate a video from a text prompt

```bash
curl http://localhost:8080/video \
  -H "Content-Type: application/json" \
  -d '{
    "model": "video-model",
    "prompt": "A cat playing in a garden on a sunny day",
    "width": 512,
    "height": 512,
    "num_frames": 16,
    "fps": 8
  }'
```

### Example response

```json
{
  "created": 1709900000,
  "id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "data": [
    {
      "url": "/generated-videos/abc123.mp4"
    }
  ]
}
```

### Generate with a starting image

```bash
curl http://localhost:8080/video \
  -H "Content-Type: application/json" \
  -d '{
    "model": "video-model",
    "prompt": "A timelapse of flowers blooming",
    "start_image": "https://example.com/flowers.jpg",

    "step": 30
  }'
```

### Get base64-encoded output

```bash
curl http://localhost:8080/video \
  -H "Content-Type: application/json" \
  -d '{
    "model": "video-model",
    "prompt": "Ocean waves on a beach",
    "response_format": "b64_json"
  }'
```
