> Chỉnh sửa hình ảnh dựa trên chỉ dẫn với 1-4 hình ảnh tham chiếu và đầu ra có thể chọn jpeg, png hoặc webp

Chỉnh sửa hình ảnh từ chỉ dẫn văn bản tối đa 2000 ký tự bằng tiếng Trung hoặc tiếng Anh. Cung cấp 1 đến 4 hình ảnh trong `image_urls` và tham chiếu chúng là image 1 đến image 4 trong lời nhắc. Có sáu giá trị đặt sẵn cho `image_size`, còn `num_images` là 1-4. Hỗ trợ `negative_prompt` tối đa 500 ký tự và `output_format` là jpeg, png hoặc webp.

- 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/v2.7/edit`
- Quote: `POST https://api.doitong.com/v1/quote/wan/v2.7/edit`

## 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/v2.7/edit` 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.

|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  | 1 – 2000 characters | Mô tả chỉnh sửa hình ảnh được yêu cầu, viết bằng tiếng Trung hoặc tiếng Anh. |
| `image_urls` | `images` | array of image URL | yes |  |  | Hình ảnh tham chiếu chỉnh sửa, bắt buộc 1–4 hình ảnh. Tham chiếu trong lời nhắc theo thứ tự cung cấp: image 1 là hình đầu tiên, image 2 là hình thứ hai, image 3 là hình thứ ba và image 4 là hình thứ tư. |
| `negative_prompt` |  | string \| null | no | `` | ≤ 500 characters | Nội dung cần loại trừ khỏi hình ảnh kết quả, giới hạn 500 ký tự. |

| `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` |  | Kiểm soát mở rộng lời nhắc DashScope, chỉ khả dụng trong chế độ chỉnh sửa hình ảnh. |
| `seed` |  | integer \| null | no |  |  | Seed ngẫu nhiên cho phép tái lập kết quả, trong khoảng 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. |
| `output_format` |  | enum (string) | no | `jpeg` | `jpeg`, `png`, `webp` | Định dạng tệp của hình ảnh đầu ra. |

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/v2.7/edit?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/v2.7/edit?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/v2.7/edit", 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/edit",
      "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.
