# Wan 3.0 Prime · Reference to Video API

> Multimodal reference-to-video gamit ang hanggang 10 larawan, 5 clip at 5 audio file, na may 2-30 segundong haba

Gumagawa ng video mula sa reference na mga larawan (hanggang 10), video (hanggang 5, kabuuang 15 segundo) at audio (hanggang 5, kabuuang 15 segundo), na tinutukoy ayon sa posisyon sa isang `prompt` na hanggang 20,000 character. Ang duration ay 2-30 segundo o smart length, ang resolution ay 480p, 720p o 1080p, at maaaring adaptive ang aspect ratio. Kailangan ng mga source na `file_url` at `web_url` ang `enable_thinking`.

- Model id: `alibaba/wan-3.0-prime/reference-to-video`
- Made by: Alibaba
- Category: Reference to Video
- Output: video
- Price: from $0.068 / second (5 s ≈ $0.34) (cheapest run $0.34 (340 API credits))
- Run: `POST https://api.doitong.ru/v1/run/alibaba/wan-3.0-prime/reference-to-video`
- Quote: `POST https://api.doitong.ru/v1/quote/alibaba/wan-3.0-prime/reference-to-video`

## Pricing

Price: **from $0.068 / second (5 s ≈ $0.34)** (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: $0.14 (140 API credits) / second
- When `resolution` = 1080p: $0.28 (280 API credits) / second

The full example input below costs $1.40 = 1400 API credits (5 s × 280 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.ru/v1/quote/alibaba/wan-3.0-prime/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 | Ilarawan kung paano isasama ang reference media, at tukuyin ang bawat reference ayon sa posisyon nito sa prompt. Halimbawa: 'the subject in Image 1 walks past Video 1'. |
| `resolution` |  | enum (string) | no | `1080p` | `480p`, `720p`, `1080p` | Resolution tier para sa resultang video. |
| `aspect_ratio` |  | enum (string) | no | `adaptive` | `adaptive`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Aspect ratio ng output, na may available na adaptive selection. |
| `duration` |  | integer \| null | no | `5` | 2 – 30 | Haba ng output: pinapagana ng null ang smart duration batay sa prompt at reference media; kung hindi, tinutukoy ng ibinigay na value ang mga segundo. |
| `audio` |  | boolean | no | `true` |  | Kinokontrol kung isasama ang nabuong audio. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Kinokontrol kung matalinong muling isusulat ang prompt bago ang pagbuo. Asahan ang posibleng pagbaba ng kalidad kapag hindi pinagana ang muling pagsulat, kapalit ng humigit-kumulang 20–60 segundong mas maikling latency. |
| `enable_thinking` |  | boolean | no | `false` |  | Pinapagana ang karagdagang reasoning bago magsimula ang pagbuo. |
| `seed` |  | integer \| null | no |  | 0 – 2,147,483,647 |  |
| `enable_safety_checker` |  | boolean | no | `true` |  | Moderation ng input at output, ipinapatupad sa bawat kahilingan maliban kung awtorisado ang account na i-disable ito at naka-off ang opsyon. |
| `reference_image_urls` | `images` | array of image URL | no |  | ≤ 10 items | Mga URL ng reference larawan, hanggang 10. |
| `reference_video_urls` |  | array of video URL | no |  | ≤ 5 items | Magbigay ng mga URL para sa reference clip na tumatakbo sa 16 fps o mas mataas. Maaaring maglaman ang set ng hanggang 5 video, na may kabuuang footage na hindi lalampas sa 15 segundo. |
| `reference_audio_urls` |  | array of audio URL | no |  | ≤ 5 items | Mga URL ng reference audio, hanggang 5 at may pinagsamang duration na hindi lalampas sa 15 segundo. |
| `file_url` |  | string (file URL) \| null | no |  |  | URL ng dokumentong ginagamit bilang batayan ng video. Nangangailangan ng enable_thinking na true. |
| `web_url` |  | string \| null | no |  |  | URL ng webpage na ginagamit bilang batayan ng video, mababasa lamang nang walang login at kapag enable_thinking=true. |

File parameters (`images`, `reference_video_urls`, `reference_audio_urls`, `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": "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.ru/v1/run/alibaba/wan-3.0-prime/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.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.ru/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/alibaba/wan-3.0-prime/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.ru/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/alibaba/wan-3.0-prime/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.ru/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-prime/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.
