# Wan 3.0 Reference to Video API

> Baut e 2 bis 30 Sekonne Wan 3.0 Clip aus bis zu 10 Biller, 5 Videoen a 5 Audioclips.

Wan 3.0 Referenz-zu-Video kombinéiert Referenzbiller, kuerz Referenzvideoen (insgesamt 15 Sekonnen) an Referenzaudio zu engem generéierte Clip; schwätzt se am Prompt no hirer Positioun un (Image 1, Video 1). Mam aktive Reasoning-Schrëtt kann de Video och op engem Dokument oder enger ëffentlecher Websäit baséieren. 480p bis 1080p, 2 bis 30 Sekonnen, generéierten Audio par défaut.

- 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/lb/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 | Beschreiwen, wéi d'Referenzmedie sollen agebonne ginn, andeems eenzel Referenzen iwwer hir Positioun am Prompt identifizéiert ginn. Beispill: 'the subject in Image 1 walks past Video 1'. |
| `resolution` |  | enum (string) | no | `1080p` | `480p`, `720p`, `1080p` | Opléisungsstuf vum resultéierende Video. |
| `aspect_ratio` |  | enum (string) | no | `adaptive` | `adaptive`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Bildformat vum Output, mat adaptiver Auswiel. |
| `duration` |  | integer \| null | no | `5` | 2 – 30 | Output-Dauer: null aktivéiert eng intelligent Dauer op Basis vum Prompt an de Referenzmedien; soss spezifizéiert de geliwwerte Wäert d'Sekonnen. |
| `audio` | `generate_audio` | boolean | no | `true` |  | Bestëmmt, ob generéierten Audio abegraff gëtt. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Bestëmmt, ob de Prompt virun der Generatioun intelligent ëmgeschriwwe gëtt. Wann d'Ëmschreiwung deaktivéiert gëtt, ass eng méiglech Qualitéitsreduktioun ze erwaarden, am Austausch géint ongeféier 20–60 Sekonne manner Latenz. |
| `enable_thinking` |  | boolean | no | `false` |  | Aktivéiert zousätzlech Iwwerleeungen, ier d'Generatioun ufänkt. |
| `seed` |  | integer \| null | no |  | 0 – 2,147,483,647 |  |
| `reference_image_urls` | `images` | array of image URL | no |  | ≤ 10 items | URLen vu Referenzbiller, maximal 10. |
| `reference_video_urls` | `videos` | array of video URL | no |  | ≤ 5 items | URLen vu Referenzclips mat 16 fps oder méi uginn. D'Sammlung däerf bis zu 5 Videoen enthalen, mat insgesamt maximal 15 Sekonne Material. |
| `reference_audio_urls` | `audios` | array of audio URL | no |  | ≤ 5 items | URLen vu Referenzaudio, maximal 5, mat enger kombinéierter Dauer vu höchstens 15 Sekonnen. |
| `file_url` |  | string (file URL) \| null | no |  |  | URL vun engem Dokument, dat als Basis fir de Video benotzt gëtt. Erfordert enable_thinking=true. |
| `web_url` |  | string \| null | no |  |  | Websäit-URL als Basis vum Video; nëmmen ouni Login liesbar a nëmme mat 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 '{
    "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

payload = {
    "prompt": "The fox from Image 1 runs through the forest from Video 1 at night, fireflies everywhere",

# 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.
