# Wan-2.2 Animate Replace API

> Sostituisce la persona in un video con un personaggio da un'immagine di riferimento, mantenendo la scena originale

Accetta un `video_url` di input e un `image_url` del personaggio, quindi sostituisce il soggetto del video con il personaggio dell'immagine mantenendo il resto della scena. Scegli 480p, 580p o 720p per `resolution`. L'immagine viene ridimensionata e ritagliata al centro quando non si adatta. `use_turbo` e `return_frames_zip` sono opzionali.

- Model id: `wan/v2.2-14b/animate/replace`
- Made by: Alibaba
- Category: Video to Video
- Output: video
- Price per second of your input video: from $0.04 / second of input video (cheapest run $0.04 (40 API credits))
- Run: `POST https://api.doitong.com/v1/run/wan/v2.2-14b/animate/replace`
- Quote: `POST https://api.doitong.com/v1/quote/wan/v2.2-14b/animate/replace`
- Docs page: https://doitong.com/it/developers/models/wan/v2.2-14b/animate/replace

## Pricing

Price: **from $0.04 / second of input video** (the lowest tier; the quote prices your exact input). Price per second of your input video: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

Price by tier:

- 480p: $0.04 / second of input video
- 580p: $0.06 / second of input video
- 720p: $0.08 / second of input video

The full example input below costs $0.75 = 750 API credits (18.75 s input video × $0.04 (480p)).

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/wan/v2.2-14b/animate/replace` 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 |
|---|---|---|---|---|---|---|
| `video_url` | `video` | string (video URL) | yes |  |  | URL del video di input. |
| `image_url` | `image` | string (image URL) | yes |  |  | URL dell'immagine sorgente; il rapporto d'aspetto selezionato determina se è necessario il preprocessing: una mancata corrispondenza attiva il ridimensionamento seguito da un ritaglio centrale. |
| `guidance_scale` |  | number | no | `1` | 1 – 10 | Intensità della guida senza classificatore, che scambia una possibile perdita di qualità con una corrispondenza più stretta al prompt all'aumentare della scala. |
| `resolution` |  | enum (string) | no | `480p` | `480p`, `580p`, `720p` | Risoluzione del video di output: 480p, 580p o 720p. |
| `seed` |  | integer \| null | no |  |  | Seed che rende riproducibile la generazione. Impostarlo su None seleziona casualmente un seed. |
| `num_inference_steps` |  | integer | no | `20` | 2 – 40 | Numero di passaggi di campionamento, che scambia un tempo di elaborazione maggiore con una qualità migliore all'aumentare del conteggio. |
| `enable_safety_checker` |  | boolean | no | `false` |  | Controllo di sicurezza dell'input prima dell'elaborazione, che solo gli account autorizzati possono disattivare. Le richieste prive di autorizzazione vengono sempre controllate; diversamente, true abilita il controllo. |
| `enable_output_safety_checker` |  | boolean | no | `false` |  | Controlla il controllo di sicurezza del video generato; impostando true si abilita un controllo dopo la generazione. |
| `shift` |  | number | no | `5` | 1 – 10 | Impostazione dello spostamento video, con intervallo consentito di 1.0–10.0. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Impostazione della qualità del video di output, che all'aumentare del valore scambia file più grandi con immagini migliori. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Modalità di scrittura del video, con balanced come compromesso tra velocità e qualità. Scegli small per i file più piccoli e la scrittura più lenta; una scrittura più rapida restituisce prima i risultati ma crea file più grandi. |
| `return_frames_zip` |  | boolean | no | `false` |  | Includi un'ulteriore esportazione senza perdita dei fotogrammi come immagini impostando questo valore su true. Le immagini vengono generate sulla GPU e inserite in un archivio ZIP. |
| `use_turbo` |  | boolean | no | `false` |  | Interruttore per il miglioramento della qualità che, quando è true, ottimizza automaticamente i parametri per ottenere i risultati migliori, combinando una generazione più rapida con una qualità superiore. |

File parameters (`video`, `image`) 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
{
  "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json
{
  "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
  "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

## 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/wan/v2.2-14b/animate/replace?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{

    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }'

# 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"

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": "wan/v2.2-14b/animate/replace",
      "input": {
        "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
        "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
      },
      "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.
