# Nano Banana Pro Edit API

> ویرایش یا ترکیب عکس‌ها با دستورهای زبان طبیعی، با حفظ چهره‌ها و محصولات، تا 4K.

حالت ویرایش Nano Banana Pro: یک یا چند تصویر بدهید و تغییر را توصیف کنید؛ مانند تعویض پس‌زمینه، ترکیب یک فرد و محصول در یک صحنه، تغییر سبک یا اصلاح متن روی تابلو. هویت‌ها و جزئیات را در ویرایش‌ها ثابت نگه می‌دارد. خروجی 1K، 2K یا 4K با هر نسبت تصویر رایج، اتصال اختیاری به وب و حداکثر چهار نتیجه در هر درخواست است.

- Model id: `nano-banana-pro/edit`
- Made by: Google
- Category: Image Editing
- Output: image
- Price: from $0.15 / image (cheapest run $0.15 (150 API credits))
- Run: `POST https://api.doitong.com/v1/run/nano-banana-pro/edit`
- Quote: `POST https://api.doitong.com/v1/quote/nano-banana-pro/edit`
- Docs page: https://doitong.com/fa/developers/models/nano-banana-pro/edit

## Pricing

Price: **from $0.15 / image** (the lowest tier; the quote prices your exact input). Billed per generated image (`num_images`, default 1).

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `resolution` = 4K and `enable_web_search` = true: $0.315 (315 API credits) / image
- When `resolution` = 4K: $0.30 (300 API credits) / image
- When `enable_web_search` = true: $0.165 (165 API credits) / image

The full example input below costs $0.15 = 150 API credits (1 image × 150 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/nano-banana-pro/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.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  | 3 – 50000 characters | دستورهای متنی برای ویرایش تصویر. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | تعداد تصاویر درخواستی برای تولید. |
| `seed` |  | integer \| null | no |  |  | مقدار seed که تولید اعداد تصادفی را آغاز می‌کند. |
| `aspect_ratio` |  | enum (string) \| null | no | `auto` | `auto`, `21:9`, `16:9`, `3:2`, `4:3`, `5:4`, `1:1`, `4:5`, `3:4`, `2:3`, `9:16` | نسبت تصویر حاصل. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | قالب فایل تصویر نهایی. |
| `safety_tolerance` |  | enum (string) | no | `4` | `1`, `2`, `3`, `4`, `5`, `6` | تحمل تعدیل محتوا را بین کم‌محدودکننده‌ترین سطح، 6، و سخت‌گیرانه‌ترین سطح، 1، تنظیم می‌کند؛ سطح 1 بیشتر محتوا را مسدود می‌کند. |
| `image_urls` | `images` | array of image URL | yes |  |  | نشانی‌های اینترنتی شناسایی‌کننده تصاویر منبع برای ویرایش یا تولید image-to-image. |
| `system_prompt` |  | string | no | `` | ≤ 50000 characters | راهنمای اختیاری مربوط به پرسونا و سبک خروجی در سطح درخواست که به Gemini به‌عنوان دستور سیستمی یا به ارائه‌دهندگان سازگار با OpenAI به‌عنوان پیام سیستمی ارسال می‌شود. اگر مقدار خالی باشد، چیزی برای این دستور ارسال نمی‌شود. |
| `resolution` |  | enum (string) | no | `1K` | `1K`, `2K`, `4K` | وضوح تصویر خروجی. |
| `limit_generations` |  | boolean | no | `true` |  | سقف آزمایشی تولید: فعال‌کردن `True` هر دستور مربوط به تعداد تصویر در پرامپت را بازنویسی می‌کند و هر دور پرامپت‌نویسی را به 1 تولید محدود می‌کند. |
| `enable_web_search` |  | boolean | no | `false` |  | کلید جست‌وجوی وب برای تولید تصویر؛ به مدل اجازه می‌دهد اطلاعات به‌روز آنلاین را در تصویر لحاظ کند. |

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": "Put this white sneaker on a sunlit marble pedestal in a minimalist gallery, keep the shoe exactly as it is",
  "images": [
    "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.jpg"
  ]
}
```

A fuller example:

```json
{
  "prompt": "Put this white sneaker on a sunlit marble pedestal in a minimalist gallery, keep the shoe exactly as it is",
  "images": [
    "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.jpg"
  ],
  "resolution": "1K"
}
```

## 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/nano-banana-pro/edit?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Put this white sneaker on a sunlit marble pedestal in a minimalist gallery, keep the shoe exactly as it is",
    "images": [
      "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.jpg"
    ],
    "resolution": "1K"
  }'

# 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/nano-banana-pro/edit?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "Put this white sneaker on a sunlit marble pedestal in a minimalist gallery, keep the shoe exactly as it is",
    "images": [
      "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.jpg"
    ],
    "resolution": "1K"
  }),
});
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": "Put this white sneaker on a sunlit marble pedestal in a minimalist gallery, keep the shoe exactly as it is",
    "images": [
        "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.jpg",
    ],
    "resolution": "1K",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/nano-banana-pro/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": "nano-banana-pro/edit",
      "input": {
        "prompt": "Put this white sneaker on a sunlit marble pedestal in a minimalist gallery, keep the shoe exactly as it is",
        "images": [
          "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.jpg"
        ],
        "resolution": "1K"
      },
      "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.
