# Qwen Image Layered API

> یک تصویر را به چند لایه جداگانه RGBA با تعداد لایه قابل تنظیم تقسیم می‌کند

تصویر ورودی (`image_url`) را به چند لایه RGBA تبدیل می‌کند که می‌توان آن‌ها را به‌صورت مستقل ویرایش کرد. دامنه `num_layers` از 1 تا 10 و مقدار پیش‌فرض آن 4 است. `prompt` اختیاری می‌تواند برای کپشن‌گذاری تصویر استفاده شود و `num_inference_steps` حداکثر 50 است. خروجی png یا webp است و `acceleration` می‌تواند none، regular یا high باشد.

- Model id: `qwen-image-layered`

- Category: Image Editing
- Output: image
- Price: $0.05 / image (cheapest run $0.20 (200 API credits))
- Run: `POST https://api.doitong.com/v1/run/qwen-image-layered`
- Quote: `POST https://api.doitong.com/v1/quote/qwen-image-layered`
- Docs page: https://doitong.com/fa/developers/models/qwen-image-layered

## Pricing

Price: **$0.05 / image**. Billed per generated image (`num_layers`, default 1).

The full example input below costs $0.20 = 200 API credits (4 images × 50 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-layered` 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 |  |  | کپشن توصیف‌کننده تصویر ارائه‌شده. |
| `image_url` | `image` | string (image URL) | yes |  |  | URL تصویر ورودی. |
| `negative_prompt` |  | string | no | `` |  | پرامپت منفی استفاده‌شده هنگام تولید تصویر. |
| `num_inference_steps` |  | integer | no | `28` | 1 – 50 | تعداد مراحل استنتاج. |
| `guidance_scale` |  | number | no | `5` | 1 – 20 | مقیاس راهنمایی اعمال‌شده هنگام تولید تصویر. |
| `seed` |  | integer \| null | no |  |  | seed برای تصاویر تکرارپذیر: پرامپت و seed یکسان، در صورت ثابت‌بودن نسخه مدل، تصویر یکسانی تولید می‌کنند. |
| `num_layers` |  | integer | no | `4` | 1 – 10 | تعداد لایه‌هایی که باید تولید شوند. |
| `enable_safety_checker` |  | boolean | no | `true` |  | بررسی ایمنی که به‌جای تصاویر ناامن علامت‌گذاری‌شده، تصاویر سیاه برمی‌گرداند. مقدار true بررسی را فعال می‌کند؛ false آن را فقط برای حساب‌های مجاز غیرفعال می‌کند، در حالی که درخواست‌های بدون مجوز در هر حال بررسی می‌شوند. |
| `output_format` |  | enum (string) | no | `png` | `png`, `webp` | قالب فایل تصویر نهایی. |
| `acceleration` |  | enum (string) | no | `regular` | `none`, `regular`, `high` | سطح شتاب اعمال‌شده به پردازش. |

File parameters (`image`) 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
{
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json
{
  "image_url": "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-layered?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image_url": "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-layered?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "image_url": "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_url": "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-layered", 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-layered",
      "input": {
        "image_url": "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.
