# Wan2.2 I2V A14B

> Call Alibaba's Wan2.2 I2V A14B image-to-video model via the Starrise AI API.

Wan2.2 I2V A14B is an image-to-video model available through Starrise AI. Video generation is an **asynchronous call** — after submitting a task, poll `GET /v1/video/generations/{task_id}` until `status` is `succeeded`.

## Key Capabilities

* **Image-to-video** — Generate video from an image and text prompt
* **Duration control** — 3–5 seconds
* **Custom resolution** — Set `width` × `height`

## Quick Example

<CodeGroup>
  ```bash cURL theme={null}
  # Step 1 — Create task
  curl https://ai.alad.com/v1/video/generations \
    -H "Authorization: Bearer YOUR_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "model": "wan2.2-i2v-a14b",
      "prompt": "A cat playing the piano",
      "duration": 5,
      "image": "https://example.com/cat.jpg"
    }'

  # Step 2 — Poll until complete
  curl https://ai.alad.com/v1/video/generations/{TASK_ID} \
    -H "Authorization: Bearer YOUR_API_KEY"
  ```

  ```python Python theme={null}
  import requests, time

  headers = {"Authorization": "Bearer YOUR_API_KEY"}

  # Step 1 — Create task
  resp = requests.post(
      "https://ai.alad.com/v1/video/generations",
      headers=headers,
      json={
          "model": "wan2.2-i2v-a14b",
          "prompt": "A cat playing the piano",
          "duration": 5,
          "image": "https://example.com/cat.jpg",
      }
  )
  task_id = resp.json()["task_id"]

  # Step 2 — Poll until complete
  while True:
      result = requests.get(
          f"https://ai.alad.com/v1/video/generations/{task_id}",
          headers=headers
      ).json()
      status = result["data"]["status"]
      if status == "succeeded":
          print(result["data"]["url"])
          break
      elif status == "failed":
          print("Failed:", result["data"]["error"])
          break
      time.sleep(3)
  ```
