# Wan 2.7 Reference to Video API

> Joħloq vidjo li jżomm is-suġġetti tal-immaġnijiet jew klipps ta' referenza, b'għażliet għal diversi suġġetti u shots

Jiġġenera vidjo minn prompt testwali meħtieġ flimkien ma' immaġnijiet ta' referenza (`reference_image_urls`) u vidjows ta' referenza (`reference_video_urls`) li jġorru d-dehra ta' karattru jew oġġett. Diversi referenzi jistgħu jingħaqdu għal xeni b'diversi suġġetti. Agħżel minn ħames proporzjonijiet, 720p jew 1080p, u 2 sa 10 sekondi. Issettja `multi_shots` għal true biex taqsam ir-riżultat f'diversi shots minflok take kontinwu wieħed.

- Model id: `wan/v2.7/reference-to-video`
- Made by: Alibaba
- Category: Reference to Video
- Output: video
- Price per second of your output video: $0.10 / second of output video (cheapest run $0.10 (100 API credits))
- Run: `POST https://api.doitong.com/v1/run/wan/v2.7/reference-to-video`
- Quote: `POST https://api.doitong.com/v1/quote/wan/v2.7/reference-to-video`
- Docs page: https://doitong.com/mt/developers/models/wan/v2.7/reference-to-video

## Pricing

Price: **$0.10 / second of output video**. Price per second of your output 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.

The full example input below costs $0.50 = 500 API credits (5 s output video × $0.10).

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/v2.7/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 | yes |  | ≥ 1 characters | Deskrizzjoni tal-vidjo li għandu jinħoloq, limitata għal 5000 karattru. |
| `reference_image_urls` | `images` | array of image URL \| null | no |  |  | URLs tal-immaġnijiet li jiddefinixxu kif jidhru l-karattri jew l-oġġetti, b’kull fajl limitat għal 20 MB. Biex tiġġenera diversi suġġetti, ipprovdi diversi immaġnijiet ta’ referenza. |
| `reference_video_urls` |  | array of video URL \| null | no |  |  | URLs tal-vidjows li jiddefinixxu kif jidhru u jiċċaqalqu l-karattri jew l-oġġetti; il-provvista ta’ diversi vidjows tippermetti ġenerazzjoni b’diversi suġġetti. Kull fajl ma jistax ikun akbar minn 100 MB jew itwal minn 30 sekonda. |
| `negative_prompt` |  | string \| null | no |  |  | Kontenut li l-vidjo għandu jeskludi, limitat għal 500 karattru. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `16:9`, `9:16`, `1:1`, `4:3`, `3:4` | Ratio tal-aspett għall-vidjo li jirriżulta. |
| `resolution` |  | enum (string) | no | `1080p` | `720p`, `1080p` | Livell ta’ riżoluzzjoni għall-vidjo li jirriżulta. |
| `duration` |  | enum (integer) | no | `5` | `2`, `3`, `4`, `5`, `6`, `7`, `8`, `9`, `10` | Tul tal-vidjo ġġenerat, f’sekondi, minn 2 sa 10. |
| `multi_shots` |  | boolean | no | `false` |  | Kontroll tas-segmentazzjoni tax-xeni: il-prestabbilit false jipproduċi xena waħda kontinwa, filwaqt li true jattiva segmentazzjoni intelliġenti f’diversi xeni. |
| `seed` |  | integer \| null | no |  |  | Seed każwali li jippermetti riżultati riproduċibbli, minn 0 sa 2147483647. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Moderazzjoni tal-input u tal-output, infurzata fuq kull talba sakemm il-kont ma jkunx awtorizzat jiddiżattivaha u l-għażla tkun mitfija. |

File parameters (`images`, `reference_video_urls`) 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
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## 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/v2.7/reference-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

# 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

```javascript
const API = "https://api.doitong.com/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/wan/v2.7/reference-to-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
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.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/wan/v2.7/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": "wan/v2.7/reference-to-video",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.
