# Wan v2.6 Image to Image API

> Chỉnh sửa hoặc đổi kiểu bằng 1-3 hình ảnh tham chiếu và một lời nhắc, tối đa 4 đầu ra mỗi yêu cầu

Mô hình image-to-image nhận `prompt` tối đa 2000 ký tự bằng tiếng Trung hoặc tiếng Anh và 1 đến 3 hình ảnh tham chiếu trong `image_urls`. Trong lời nhắc, tham chiếu chúng là image 1, image 2 và image 3, chẳng hạn để kết hợp một kiểu với nền khác. Có sáu giá trị đặt sẵn cho `image_size` và `num_images` là 1-4. Hỗ trợ `negative_prompt` và mở rộng lời nhắc tùy chọn.

- Model id: `wan/v2.6/image-to-image`
- Made by: Alibaba
- Category: Image Editing
- Output: image
- Price: $0.03 / image (cheapest run $0.03 (30 API credits))
- Run: `POST https://api.doitong.com/v1/run/wan/v2.6/image-to-image`
- Quote: `POST https://api.doitong.com/v1/quote/wan/v2.6/image-to-image`
- Docs page: https://doitong.com/vi/developers/models/wan/v2.6/image-to-image

## Pricing

Price: **$0.03 / image**. Billed per generated image (`num_images`, default 1).

The full example input below costs $0.03 = 30 API credits (1 image × 30 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/wan/v2.6/image-to-image` 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 | Hướng dẫn tạo hình ảnh bằng tiếng Trung hoặc tiếng Anh, tối đa 2000 ký tự. Ví dụ: 'Generate an image using the style of image 1 and background of image 2'. |
| `image_urls` | `images` | array of image URL | yes |  |  | Cung cấp 1–3 hình ảnh tham chiếu chỉnh sửa ở định dạng JPEG, JPG, PNG (không alpha), BMP hoặc WEBP. Mỗi tệp không được lớn hơn 10MB, chiều rộng và chiều cao đều trong khoảng 384–5000px. Tham chiếu chúng trong lời nhắc là 'image 1', 'image 2' và 'image 3' theo thứ tự cung cấp. |
| `negative_prompt` |  | string \| null | no | `` |  | Nội dung cần loại trừ khỏi hình ảnh kết quả, giới hạn 500 ký tự. |
| `image_size` |  | object {width, height} \| enum (string) | no | `square_hd` | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9` | Đặt kích thước đầu ra với tổng số pixel từ 768*768 đến 1280*1280. Chọn preset như 'square_hd', 'landscape_16_9' hoặc 'portrait_9_16', hoặc cung cấp kích thước chính xác bằng ImageSize(width=1280, height=720). |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Số lượng hình ảnh tạo sinh, từ 1 đến 4. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Bật tối ưu hóa lời nhắc bằng LLM, đánh đổi thêm 3–4 giây xử lý. Lời nhắc đơn giản sẽ có kết quả cải thiện đáng kể. |
| `seed` |  | integer \| null | no |  |  | Seed ngẫu nhiên giúp tăng tính nhất quán khi dùng lại, hỗ trợ khả năng tái lập với giá trị từ 0 đến 2147483647. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Kiểm duyệt cả đầu vào và đầu ra, được thực thi trên mọi yêu cầu trừ khi tài khoản được cấp quyền tắt và tùy chọn này đã được tắt. |

File parameters (`images`) 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",
  "images": [
    "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  ]
}

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "image_urls": [
    "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/v2.6/image-to-image?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",
    "image_urls": [
      "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"
```

### 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/v2.6/image-to-image?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",
    "image_urls": [
      "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
    ]
  }),
});
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",
    "image_urls": [
        "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    ],
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/wan/v2.6/image-to-image", 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/v2.6/image-to-image",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "image_urls": [
          "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.
