# Wan 2.7 Reference to Video API

> إنشاء فيديو يحافظ على أشخاص أو عناصر الصور أو المقاطع المرجعية، مع خيارات لتعدد العناصر واللقطات

ينشئ فيديو من مطالبة نصية مطلوبة، بالإضافة إلى صور مرجعية (`reference_image_urls`) ومقاطع مرجعية (`reference_video_urls`) تنقل مظهر شخصية أو عنصر. يمكن دمج عدة مراجع لإنشاء مشاهد متعددة العناصر. اختر من خمس نسب أبعاد، بدقة 720p أو 1080p، ومدة من 2 إلى 10 ثوانٍ. اضبط `multi_shots` على true لتقسيم الناتج إلى عدة لقطات بدلًا من لقطة متصلة واحدة.

- Model id: `wan/v2.7/reference-to-video`
- Made by: Alibaba
- Category: Reference to Video
- Output: video
- Price per second of your output video: $0.10 / second of output video (cheapest run $0.10 (100 API credits))
- Run: `POST https://api.doitong.com/v1/run/wan/v2.7/reference-to-video`
- Quote: `POST https://api.doitong.com/v1/quote/wan/v2.7/reference-to-video`
- Docs page: https://doitong.com/ar/developers/models/wan/v2.7/reference-to-video

## Pricing

Price: **$0.10 / second of output video**. Price per second of your output video: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

The full example input below costs $0.50 = 500 API credits (5 s output video × $0.10).

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/wan/v2.7/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 | yes |  | ≥ 1 characters | وصف الفيديو المراد إنشاؤه، بحد أقصى 5000 حرف. |
| `reference_image_urls` | `images` | array of image URL \| null | no |  |  | عناوين URL لصور تحدد مظهر الشخصيات أو الكائنات، بحد أقصى 20 MB لكل ملف. لتوليد عدة عناصر، أرسل عدة صور مرجعية. |
| `reference_video_urls` |  | array of video URL \| null | no |  |  | عناوين URL لفيديوهات تحدد مظهر الشخصيات أو الكائنات وحركتها؛ يتيح إرسال عدة فيديوهات التوليدَ بعناصر متعددة. يجب ألا يتجاوز حجم أي ملف 100 MB ولا مدته 30 ثانية. |
| `negative_prompt` |  | string \| null | no |  |  | المحتوى الذي يجب أن يستبعده الفيديو، بحد أقصى 500 حرف. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `16:9`, `9:16`, `1:1`, `4:3`, `3:4` | نسبة العرض إلى الارتفاع للفيديو الناتج. |
| `resolution` |  | enum (string) | no | `1080p` | `720p`, `1080p` | فئة دقة الفيديو الناتج. |
| `duration` |  | enum (integer) | no | `5` | `2`, `3`, `4`, `5`, `6`, `7`, `8`, `9`, `10` | مدة الفيديو المُولّد، بالثواني، من 2 إلى 10. |
| `multi_shots` |  | boolean | no | `false` |  | التحكم في تقسيم اللقطات: ينتج false الافتراضي لقطة متصلة واحدة، بينما يفعّل true التقسيم الذكي إلى عدة لقطات. |
| `seed` |  | integer \| null | no |  |  | بذرة عشوائية تتيح نتائج قابلة لإعادة الإنتاج، من 0 إلى 2147483647. |
| `enable_safety_checker` |  | boolean | no | `true` |  | تطبيق الإشراف على المدخل والمخرج مع كل طلب، ما لم يكن الحساب مخولًا لتعطيله وكان الخيار متوقفًا. |

File parameters (`images`, `reference_video_urls`) 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
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## 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/wan/v2.7/reference-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

# 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

```javascript
const API = "https://api.doitong.com/v1";
const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/wan/v2.7/reference-to-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
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
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

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

payload = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/wan/v2.7/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": "wan/v2.7/reference-to-video",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.
