# Wan 3.0 Reference to Video API

> زیادہ سے زیادہ 10 تصاویر، 5 ویڈیوز اور 5 آڈیو کلپس سے 2 سے 30 سیکنڈ کا Wan 3.0 کلپ بناتا ہے۔

Wan 3.0 ریفرنس-ٹو-ویڈیو ریفرنس تصاویر، مختصر ریفرنس ویڈیوز (کل 15 سیکنڈ) اور ریفرنس آڈیو کو ایک تخلیق شدہ کلپ میں یکجا کرتا ہے؛ پرامپٹ میں انہیں پوزیشن (Image 1، Video 1) کے ذریعے مخاطب کریں۔ ریزننگ سٹیپ آن ہونے کے ساتھ یہ ویڈیو کو کسی دستاویز یا عوامی ویب پیج پر بھی مبنی کر سکتا ہے۔ 480p سے 1080p، 2 سے 30 سیکنڈ، ڈیفالٹ طور پر آڈیو تخلیق کے ساتھ۔

- 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/ur/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 | حوالہ میڈیا شامل کرنے کا طریقہ بیان کریں، پرامپٹ میں انفرادی حوالوں کی پوزیشن سے شناخت کرتے ہوئے۔ مثال: 'the subject in Image 1 walks past Video 1'۔ |
| `resolution` |  | enum (string) | no | `1080p` | `480p`, `720p`, `1080p` | نتیجہ خیز ویڈیو کے لیے ریزولوشن کا درجہ۔ |
| `aspect_ratio` |  | enum (string) | no | `adaptive` | `adaptive`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | آؤٹ پٹ کا aspect ratio؛ adaptive انتخاب دستیاب ہے۔ |
| `duration` |  | integer \| null | no | `5` | 2 – 30 | آؤٹ پٹ کی لمبائی: null پرامپٹ اور حوالہ میڈیا کی بنیاد پر اسمارٹ دورانیہ فعال کرتا ہے؛ بصورتِ دیگر فراہم کردہ قدر سیکنڈ کی وضاحت کرتی ہے۔ |
| `audio` | `generate_audio` | boolean | no | `true` |  | کنٹرول کرتا ہے کہ تخلیق کردہ آڈیو شامل ہو یا نہیں۔ |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | کنٹرول کریں کہ تخلیق سے پہلے پرامپٹ ذہانت سے دوبارہ لکھا جائے یا نہیں۔ rewriting غیر فعال کرنے پر معیار میں ممکنہ کمی کے بدلے تقریباً 20–60 سیکنڈ کم latency متوقع ہے۔ |
| `enable_thinking` |  | boolean | no | `false` |  | تخلیق شروع ہونے سے پہلے اضافی reasoning فعال کرتا ہے۔ |
| `seed` |  | integer \| null | no |  | 0 – 2,147,483,647 |  |
| `reference_image_urls` | `images` | array of image URL | no |  | ≤ 10 items | حوالہ تصاویر کے URLs، زیادہ سے زیادہ 10۔ |
| `reference_video_urls` | `videos` | array of video URL | no |  | ≤ 5 items | 16 fps یا اس سے زیادہ پر چلنے والے حوالہ کلپس کے URLs فراہم کریں۔ سیٹ میں زیادہ سے زیادہ 5 ویڈیوز اور مجموعی طور پر 15 سیکنڈ سے زیادہ فوٹیج نہیں ہو سکتی۔ |
| `reference_audio_urls` | `audios` | array of audio URL | no |  | ≤ 5 items | حوالہ آڈیو کے URLs، زیادہ سے زیادہ 5، مجموعی دورانیہ 15 سیکنڈ سے زیادہ نہ ہو۔ |
| `file_url` |  | string (file URL) \| null | no |  |  | ویڈیو کی بنیاد کے طور پر استعمال ہونے والی دستاویز کا URL۔ enable_thinking کا true ہونا ضروری ہے۔ |
| `web_url` |  | string \| null | no |  |  | ویڈیو کی بنیاد کے طور پر استعمال ہونے والے ویب صفحے کا URL؛ صرف بغیر login کے قابلِ مطالعہ اور صرف enable_thinking=true کے ساتھ۔ |

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

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

    "resolution": "720p"
  }),
});
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

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",

}

# 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.
