# Wan 3.0 Reference to Video API

> کلیپ 2 تا 30 ثانیه‌ای Wan 3.0 را از حداکثر 10 تصویر، 5 ویدیو و 5 کلیپ صوتی می‌سازد.

Wan 3.0 reference-to-video تصاویر مرجع، ویدیوهای مرجع کوتاه (در مجموع 15 ثانیه) و صوت مرجع را در یک کلیپ تولیدشده ترکیب می‌کند؛ در پرامپت با موقعیت آن‌ها (Image 1، Video 1) ارجاع دهید. با فعال بودن مرحله استدلال، ویدیو می‌تواند بر اساس سند یا صفحه وب عمومی نیز ساخته شود. وضوح 480p تا 1080p، مدت 2 تا 30 ثانیه و صوت تولیدشده به‌طور پیش‌فرض.

- Model id: `alibaba/wan-3.0/reference-to-video`
- Made by: Alibaba
- Category: Reference to Video
- Output: video
- Price: from $0.05 / second (5 s ≈ $0.25) (cheapest run $0.25 (250 API credits))
- Run: `POST https://api.doitong.com/v1/run/alibaba/wan-3.0/reference-to-video`
- Quote: `POST https://api.doitong.com/v1/quote/alibaba/wan-3.0/reference-to-video`
- Docs page: https://doitong.com/fa/developers/models/alibaba/wan-3.0/reference-to-video

## Pricing

Price: **from $0.05 / second (5 s ≈ $0.25)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 30).

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `resolution` = 720p: $0.10 (100 API credits) / second
- When `resolution` = 1080p: $0.20 (200 API credits) / second

The full example input below costs $0.50 = 500 API credits (5 s × 100 API credits).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/alibaba/wan-3.0/reference-to-video` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Input parameters

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `prompt` |  | string \| null | no |  | ≤ 20000 characters | نحوه به‌کارگیری رسانه مرجع را توضیح دهید و با جایگاه هر مرجع در پرامپت آن را مشخص کنید. برای مثال: 'the subject in Image 1 walks past Video 1'. |
| `resolution` |  | enum (string) | no | `1080p` | `480p`, `720p`, `1080p` | سطح وضوح ویدیوی نهایی. |
| `aspect_ratio` |  | enum (string) | no | `adaptive` | `adaptive`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | نسبت تصویر خروجی، با امکان انتخاب تطبیقی. |
| `duration` |  | integer \| null | no | `5` | 2 – 30 | مدت خروجی: مقدار null مدت هوشمند را بر اساس پرامپت و رسانه مرجع فعال می‌کند؛ در غیر این صورت، مقدار ارائه‌شده ثانیه را مشخص می‌کند. |
| `audio` | `generate_audio` | boolean | no | `true` |  | مشخص می‌کند صوت تولیدشده گنجانده شود یا خیر. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | بازنویسی هوشمند پرامپت پیش از تولید را کنترل می‌کند. غیرفعال‌کردن بازنویسی احتمالاً کیفیت را کاهش می‌دهد، اما حدود 20–60 ثانیه از تأخیر کم می‌کند. |
| `enable_thinking` |  | boolean | no | `false` |  | استدلال اضافی پیش از آغاز تولید را فعال می‌کند. |
| `seed` |  | integer \| null | no |  | 0 – 2,147,483,647 |  |
| `reference_image_urls` | `images` | array of image URL | no |  | ≤ 10 items | نشانی‌های اینترنتی تصاویر مرجع، حداکثر 10 مورد. |
| `reference_video_urls` | `videos` | array of video URL | no |  | ≤ 5 items | نشانی‌های اینترنتی قطعه‌های مرجع با نرخ 16 fps یا بیشتر ارائه دهید. مجموعه می‌تواند حداکثر 5 ویدیو داشته باشد و مجموع مدت آن‌ها نباید از 15 ثانیه بیشتر شود. |
| `reference_audio_urls` | `audios` | array of audio URL | no |  | ≤ 5 items | نشانی‌های اینترنتی صوت مرجع، حداکثر 5 مورد با مجموع مدت حداکثر 15 ثانیه. |
| `file_url` |  | string (file URL) \| null | no |  |  | نشانی اینترنتی سندی که مبنای ویدیو است. enable_thinking باید true باشد. |
| `web_url` |  | string \| null | no |  |  | نشانی اینترنتی صفحه وب مبنای ویدیو؛ فقط بدون ورود به حساب و فقط با enable_thinking=true قابل خواندن است. |

File parameters (`images`, `videos`, `audios`, `file_url`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## Example input

Required parameters only:

```json
{}
```

A fuller example:

```json
{
  "prompt": "The fox from Image 1 runs through the forest from Video 1 at night, fireflies everywhere",
  "images": [
    "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  ],
  "duration": 5,
  "resolution": "720p"
}
```

## Run it

Set `DOITONG_API_KEY` to a key from https://doitong.com/developers/dashboard#keys. `?wait=20` returns the finished request in the same call when it is ready within 20 seconds; otherwise poll `GET /requests/{id}` (it also accepts `?wait=`), or pass `webhook_url`.

### curl

```bash
# Run the model; wait up to 20 s for the finished result in the same call
curl -X POST "https://api.doitong.com/v1/run/alibaba/wan-3.0/reference-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "The fox from Image 1 runs through the forest from Video 1 at night, fireflies everywhere",
    "images": [
      "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
    ],
    "duration": 5,
    "resolution": "720p"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

  }),
});
let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is

  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();

### Python

```python
import os

API = "https://api.doitong.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "prompt": "The fox from Image 1 runs through the forest from Video 1 at night, fireflies everywhere",
    "images": [
        "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    ],
    "duration": 5,
    "resolution": "720p",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/alibaba/wan-3.0/reference-to-video", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is
while request["status"] in ("queued", "running"):
    request = requests.get(API + "/requests/" + request["id"], params={"wait": 20}, headers=headers).json()
if request["status"] != "succeeded":
    raise RuntimeError(request["error"])
print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### MCP

The MCP server at `https://api.doitong.com/v1/mcp` exposes the tools `search_models`, `get_model`, `quote`, `run`, `get_request`, `cancel_request`, `list_requests`, `create_upload` and `get_account`. A `run` call for this model:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "run",
    "arguments": {
      "model_id": "alibaba/wan-3.0/reference-to-video",
      "input": {
        "prompt": "The fox from Image 1 runs through the forest from Video 1 at night, fireflies everywhere",
        "images": [
          "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
        ],
        "duration": 5,
        "resolution": "720p"
      },
      "wait_seconds": 20
    }
  }
}
```

## Response

Every call returns a request object. `status` is one of `queued`, `running`, `succeeded`, `failed`, `canceled`. `outputs` lists the generated files with URLs on our storage (kept forever, or 7 days with `?storage=temporary`; `storage` says which); `output` is the model's own result object with the same URLs.
