# Wan 3.0 Reference to Video API

> Kuria 2–30 sekundžių Wan 3.0 klipą iš iki 10 vaizdų, 5 vaizdo įrašų ir 5 garso klipų.

Wan 3.0 reference-to-video sujungia referencinius vaizdus, trumpus referencinius vaizdo įrašus (iš viso 15 sekundžių) ir referencinį garsą į vieną sugeneruotą klipą; raginime nurodykite juos pagal poziciją (Image 1, Video 1). Įjungus samprotavimo žingsnį, vaizdo įrašas taip pat gali būti grindžiamas dokumentu arba viešu tinklalapiu. 480p–1080p, 2–30 sekundžių, pagal numatytuosius nustatymus generuojamas garsas.

- 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/lt/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 | Aprašykite, kaip įtraukti referencinę mediją, atskiras nuorodas raginime nurodydami pagal jų vietą. Pavyzdžiui: 'the subject in Image 1 walks past Video 1'. |
| `resolution` |  | enum (string) | no | `1080p` | `480p`, `720p`, `1080p` | Galutinio vaizdo įrašo raiškos lygis. |
| `aspect_ratio` |  | enum (string) | no | `adaptive` | `adaptive`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Išvesties kraštinių santykis; galima adaptyvi atranka. |
| `duration` |  | integer \| null | no | `5` | 2 – 30 | Išvesties trukmė: null įjungia išmanią trukmę pagal raginį ir referencinę mediją; kitu atveju pateikta reikšmė nurodo sekundes. |
| `audio` | `generate_audio` | boolean | no | `true` |  | Nurodo, ar įtraukiamas sugeneruotas garsas. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Nurodo, ar raginys prieš generavimą išmaniai perrašomas. Išjungus perrašymą tikėtinas kokybės sumažėjimas, tačiau delsa sutrumpėja maždaug 20–60 sekundžių. |
| `enable_thinking` |  | boolean | no | `false` |  | Prieš pradedant generuoti įjungia papildomą samprotavimą. |
| `seed` |  | integer \| null | no |  | 0 – 2,147,483,647 |  |
| `reference_image_urls` | `images` | array of image URL | no |  | ≤ 10 items | Referencinių vaizdų URL, ne daugiau kaip 10. |
| `reference_video_urls` | `videos` | array of video URL | no |  | ≤ 5 items | Pateikite referencinių klipų URL; jų dažnis turi būti 16 fps arba didesnis. Rinkinyje gali būti iki 5 vaizdo įrašų, o bendra trukmė negali viršyti 15 sekundžių. |
| `reference_audio_urls` | `audios` | array of audio URL | no |  | ≤ 5 items | Referencinių garso įrašų URL; ne daugiau kaip 5, o bendra trukmė negali viršyti 15 sekundžių. |
| `file_url` |  | string (file URL) \| null | no |  |  | Dokumento, naudojamo kaip vaizdo įrašo pagrindas, URL. Reikšmė enable_thinking turi būti true. |
| `web_url` |  | string \| null | no |  |  | Tinklalapio, naudojamo kaip vaizdo įrašo pagrindas, URL; jis turi būti pasiekiamas neprisijungus ir tik kai enable_thinking=true. |

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 '{

    "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

payload = {

# 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

### 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.
