# Qwen Image Edit Plus Lora Gallery · Remove Element API

> Xóa các vật thể, người hoặc văn bản được nêu trong lời nhắc, đồng thời giữ phần còn lại của hình ảnh nhất quán

LoRA cài sẵn để xóa phần tử. Cung cấp `image_urls` và nêu nội dung cần xóa trong `prompt`, chẳng hạn vật thể, người hoặc văn bản. Phần còn lại của ảnh được giữ nhất quán. Mặc định 6 bước; tối đa 4 ảnh ở định dạng png, jpeg hoặc webp.

## Pricing

Price: **$0.035 / image**. Estimated from the typical cost of one run, per output (`num_images`). The quote is exactly what the run charges.

The full example input below costs $0.035 = 35 API credits (1 image × 35 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/qwen-image-edit-plus-lora-gallery/remove-element` 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 |
|---|---|---|---|---|---|---|
| `image_urls` | `images` | array of image URL | yes |  |  | URL của hình ảnh nguồn có các thành phần cần xóa. |
| `image_size` |  | object {width, height} \| enum (string) \| null | no |  | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9` | Ghi đè kích thước đầu ra; nếu không có, hình ảnh được tạo lấy kích thước từ hình ảnh đầu vào cuối cùng. |
| `guidance_scale` |  | number | no | `1` | 0 – 20 | Kiểm soát mức độ tuân thủ lời nhắc bằng scale CFG, trong đó CFG là viết tắt của Classifier Free Guidance. |
| `num_inference_steps` |  | integer | no | `6` | 2 – 50 | Số bước suy luận cần chạy. |
| `acceleration` |  | enum (string) | no | `regular` | `none`, `regular` | Thiết lập tăng tốc tạo sinh hình ảnh. Chọn 'regular' để cân bằng giữa tốc độ và chất lượng. |
| `negative_prompt` |  | string | no | `` |  | Lời nhắc phủ định dùng trong quá trình tạo sinh. |
| `seed` |  | integer \| null | no |  |  | Seed tạo sinh ngẫu nhiên cho phép tái tạo kết quả bằng cách giữ nguyên cả lời nhắc và seed. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Nút bật/tắt kiểm tra an toàn hình ảnh đã tạo; chỉ tài khoản được ủy quyền mới có thể tắt. Kiểm tra vẫn bắt buộc đối với các yêu cầu không có quyền ủy quyền. |
| `output_format` |  | enum (string) | no | `png` | `png`, `jpeg`, `webp` | Định dạng của hình ảnh kết quả. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Số hình ảnh cần tạo. |
| `prompt` |  | string | no | `Remove the specified element from the scene` |  | Xác định nội dung hình ảnh không mong muốn—chẳng hạn người, vật thể hoặc văn bản—để xóa sạch mà vẫn giữ tính nhất quán của phần hình ảnh còn lại. |
| `lora_scale` |  | number | no | `1` | 0 – 4 | Cường độ đóng góp của LoRA, được điều chỉnh bằng cách thay đổi tỷ lệ mô hình LoRA. |

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
{
  "images": [
    "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  ]
}
```

A fuller example:

```json
{
  "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/qwen-image-edit-plus-lora-gallery/remove-element?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "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/qwen-image-edit-plus-lora-gallery/remove-element?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "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 = {
    "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/qwen-image-edit-plus-lora-gallery/remove-element", 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": "qwen-image-edit-plus-lora-gallery/remove-element",
      "input": {
        "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.
