# Wan 3.0 Reference to Video API

> Crée un clip Wan 3.0 de 2 à 30 secondes à partir de jusqu'à 10 images, 5 vidéos et 5 clips audio.

Wan 3.0 reference-to-video combine des images de référence, de courtes vidéos de référence (15 secondes au total) et de l'audio de référence en un clip généré ; désignez-les dans le prompt par leur position (Image 1, Video 1). Avec l'étape de raisonnement activée, il peut aussi baser la vidéo sur un document ou une page web publique. 480p à 1080p, 2 à 30 secondes, audio généré 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/fr/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 | Décrivez comment intégrer les médias de référence en identifiant chaque référence par sa position dans le prompt. Exemple : 'the subject in Image 1 walks past Video 1'. |
| `resolution` |  | enum (string) | no | `1080p` | `480p`, `720p`, `1080p` | Niveau de résolution de la vidéo obtenue. |
| `aspect_ratio` |  | enum (string) | no | `adaptive` | `adaptive`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Format d'image de la sortie, avec sélection adaptative disponible. |
| `duration` |  | integer \| null | no | `5` | 2 – 30 | Durée de sortie : null active une durée intelligente basée sur le prompt et les médias de référence ; sinon, la valeur fournie spécifie le nombre de secondes. |
| `audio` | `generate_audio` | boolean | no | `true` |  | Contrôle si l'audio généré est inclus. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Contrôle si le prompt est réécrit intelligemment avant la génération. Désactiver la réécriture peut réduire la qualité, en échange d'une latence inférieure d'environ 20 à 60 secondes. |
| `enable_thinking` |  | boolean | no | `false` |  | Active un raisonnement supplémentaire avant le début de la génération. |
| `seed` |  | integer \| null | no |  | 0 – 2,147,483,647 |  |
| `reference_image_urls` | `images` | array of image URL | no |  | ≤ 10 items | URLs des images de référence, au nombre maximal de 10. |
| `reference_video_urls` | `videos` | array of video URL | no |  | ≤ 5 items | Fournissez les URLs de clips de référence à 16 fps ou plus. L'ensemble peut contenir jusqu'à 5 vidéos, pour un total maximal de 15 secondes de métrage. |
| `reference_audio_urls` | `audios` | array of audio URL | no |  | ≤ 5 items | URLs audio de référence, limitées à 5, pour une durée cumulée ne dépassant pas 15 secondes. |
| `file_url` |  | string (file URL) \| null | no |  |  | URL d'un document utilisé comme base de la vidéo. Nécessite que enable_thinking soit true. |
| `web_url` |  | string \| null | no |  |  | URL d'une page Web utilisée comme base de la vidéo, accessible uniquement sans connexion et uniquement avec 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
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.
