# Wan 3.0 Text to Video API

> Alibaba의 Wan 3.0으로, 최대 1080p에서 생성 오디오를 포함한 2~30초 클립을 생성합니다.

Wan 3.0은 프롬프트에서 2초부터 최대 30초까지 길고 일관된 장면을 렌더링하며, 기본적으로 사운드를 생성합니다. 선택적 추론 스텝은 복잡한 장면을 계획하고 프롬프트 확장은 기본적으로 켜져 있습니다. 480p, 720p 또는 1080p에서 6가지 화면 비율이나 적응형 프레이밍을 사용할 수 있습니다.

- Category: Text 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.ru/v1/run/alibaba/wan-3.0/text-to-video`
- Quote: `POST https://api.doitong.ru/v1/quote/alibaba/wan-3.0/text-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).

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.ru/v1/quote/alibaba/wan-3.0/text-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 – 20000 characters | 생성할 동영상을 설명하는 텍스트 지침입니다. |
| `resolution` |  | enum (string) | no | `1080p` | `480p`, `720p`, `1080p` | 결과 동영상의 해상도 등급입니다. |
| `aspect_ratio` |  | enum (string) | no | `adaptive` | `adaptive`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | 출력 종횡비이며 자동 선택을 지원합니다. |
| `duration` |  | integer \| null | no | `5` | 2 – 30 | 출력 길이입니다. null이면 프롬프트와 참조 미디어를 바탕으로 스마트하게 지속 시간을 정하고, 그 외에는 제공한 값이 초를 지정합니다. |
| `audio` | `generate_audio` | boolean | no | `true` |  | 생성된 오디오를 포함할지 제어합니다. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | 생성 전에 프롬프트를 지능적으로 다시 작성할지 제어합니다. 재작성을 비활성화하면 품질이 낮아질 수 있지만 지연 시간이 약 20–60초 줄어듭니다. |
| `enable_thinking` |  | boolean | no | `false` |  | 생성 전에 추가 추론을 활성화합니다. |
| `seed` |  | integer \| null | no |  | 0 – 2,147,483,647 |  |

## Example input

Required parameters only:

```json
{
  "prompt": "A red panda walks through a bamboo forest at sunrise, mist between the stalks, gentle handheld camera"
}
```

A fuller example:

```json
{
  "prompt": "A red panda walks through a bamboo forest at sunrise, mist between the stalks, gentle handheld camera",
  "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.ru/v1/run/alibaba/wan-3.0/text-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red panda walks through a bamboo forest at sunrise, mist between the stalks, gentle handheld camera",
    "duration": 5,
    "resolution": "720p"
  }'

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

### JavaScript

```javascript
const API = "https://api.doitong.ru/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/alibaba/wan-3.0/text-to-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red panda walks through a bamboo forest at sunrise, mist between the stalks, gentle handheld camera",
    "duration": 5,
    "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
import requests

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

payload = {
    "prompt": "A red panda walks through a bamboo forest at sunrise, mist between the stalks, gentle handheld camera",
    "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/text-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.ru/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/text-to-video",
      "input": {
        "prompt": "A red panda walks through a bamboo forest at sunrise, mist between the stalks, gentle handheld camera",
        "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.
