## API Information

This model can be used via our HTTP API or more conveniently via our client libraries.
See the input and output schema below, as well as the usage examples.

### Input Schema

The API accepts the following input parameters:

- **`prompt`** (`string`, _required_):
  Text prompt.
  - Examples: "An action shot of a black lab swimming..."

- **`duration`** (`int`, _optional_):
  Video duration
  - Default: `5`
  - Range: `4` to `15`

- **`resolution`** (`string`, _optional_):
  Output video resolution
  - Default: `720p`
  - Options: "480p", "720p"

- **`aspect_ratio`** (`string`, _optional_):
  The aspect ratio of the generated video frame (width:height)
  - Default: `16:9`
  - Options: "21:9", "16:9", "9:16", "4:3", "1:1", "3:4"

- **`image_urls`** (`list<string>`, _required_):
  Reference image URLs. The total number of image_urls and audio_urls must be no more than 12.

- **`is_first_last_frame`** (`bool`, _optional_):
  Enable first and last frame mode. When enabled, image_urls must contain 1 to 2 images, audio_urls must be empty, and aspect_ratio is ignored.
  - Default: `false`
  - Options: "true", "false"

- **`audio_urls`** (`list<string>`, _optional_):
  Reference audio URLs. Supported formats: MP3 and WAV. Maximum duration: 15 seconds. The total number of image_urls and audio_urls must be no more than 12.

### Output Schema

The API returns a JSON response with a `job_id` for tracking the request status.

**Create Job Response:**
```json
{
  "code": 0,
  "data": {
    "amount": "0.02",
    "job_id": "<JOB_ID>"
  }
}
```

**Query Job Result (when status is 2, meaning succeeded):**
```json
{
  "code": 0,
  "data": {
    "status": 2,
    "result": {
      "images": [{ "url": "https://..." }]
    }
  }
}
```

## Use Example

To use this model, make an HTTP POST request to the API endpoint, then poll for results using the returned `job_id`.

### Bash (cURL)
```bash
# Step 1: Create a job
response=$(curl --request POST \
  --url https://api.shortapi.ai/api/v1/job/create \
  --header "Authorization: Bearer $SHORTAPI_KEY" \
  --header "Content-Type: application/json" \
  --data '{

  "args": {
    "prompt": "The architectural line drawing smoothly evolves into a photorealistic modern city at sunset. Colors bleed into the sketch, textures of glass and steel emerge on the flowing skyscrapers. Warm golden hour sunlight begins to glow from the windows, and the river transitions from white to reflecting the city lights. Cinematic, smooth transition, high detail.",

  },
  "callback_url": "CALLBACK_URL"
}')
JOB_ID=$(echo "$response" | grep -o '"job_id": *"[^"]*"' | sed 's/"job_id": *//; s/"//g')

# Step 2: Poll for results
curl --request GET \
