- Model id: `nano-banana-2/edit`
- Made by: Google
- Category: Image Editing
- Output: image
- Price: from $0.06 / image (cheapest run $0.06 (60 API credits))
- Run: `POST https://api.doitong.com/v1/run/nano-banana-2/edit`
- Quote: `POST https://api.doitong.com/v1/quote/nano-banana-2/edit`
- Docs page: https://doitong.com/ms/developers/models/nano-banana-2/edit

## Pricing

Price: **from $0.06 / 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 `enable_web_search` = true and `thinking_level` = high: by `resolution`, 0.5K: $0.077, 1K: $0.097, 2K: $0.137, 4K: $0.177 / image
- When `enable_web_search` = true: by `resolution`, 0.5K: $0.075, 1K: $0.095, 2K: $0.135, 4K: $0.175 / image
- When `thinking_level` = high: by `resolution`, 0.5K: $0.062, 1K: $0.082, 2K: $0.122, 4K: $0.162 / image

The full example input below costs $0.08 = 80 API credits (1 image × 80 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-2/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 | Arahan teks untuk menyunting imej. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Bilangan imej yang diminta untuk penjanaan. |
| `seed` |  | integer \| null | no |  |  | Nilai seed yang memulakan penjanaan nombor rawak. |
| `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`, `4:1`, `1:4`, `8:1`, `1:8` | Nisbah aspek imej output, termasuk pilihan ekstrem 4:1, 1:4, 8:1, 1:8. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | Format fail untuk imej yang terhasil. |
| `safety_tolerance` |  | enum (string) | no | `4` | `1`, `2`, `3`, `4`, `5`, `6` | Tetapkan toleransi penyederhanaan kandungan antara tahap paling kurang ketat, 6, dan tahap paling ketat, 1, yang menyekat kebanyakan kandungan. |
| `image_urls` | `images` | array of image URL | no |  |  | Bekalkan imej sumber melalui URL untuk penyuntingan imej atau penjanaan imej-ke-imej, melainkan anda memberikan sekurang-kurangnya satu input alternatif: `video_url`, `audio_url`, atau `pdf_url`. |
| `system_prompt` |  | string | no | `` | ≤ 50000 characters | Panduan persona dan gaya output pilihan yang meliputi seluruh permintaan, dihantar kepada Gemini sebagai arahan sistem atau kepada penyedia serasi OpenAI sebagai mesej sistem. Tiada apa-apa dihantar untuk arahan ini apabila nilainya kosong. |
| `resolution` |  | enum (string) | no | `1K` | `0.5K`, `1K`, `2K`, `4K` | Resolusi untuk imej output. |
| `video_url` | `video` | string (video URL) \| null | no |  |  | Konteks video pilihan yang dibekalkan sama ada sebagai URL YouTube atau URL http(s)/data untuk fail video. Pautan YouTube sampai terus kepada model tanpa dimuat turun; fail video dimuat turun dan dihantar secara sebaris, tertakluk kepada maksimum 15 MB. |
| `audio_url` | `audio` | string (audio URL) \| null | no |  |  | Bekalkan konteks audio pilihan melalui URL http(s) atau data yang merujuk kepada fail tidak melebihi 15 MB. Fail dihantar secara sebaris selepas dimuat turun. |
| `pdf_url` |  | string \| null | no |  |  | Bekalkan konteks PDF pilihan melalui URL http(s) atau data yang merujuk kepada dokumen tidak melebihi 15 MB. Dokumen dihantar secara sebaris selepas dimuat turun. |
| `limit_generations` |  | boolean | no | `true` |  | Had penjanaan percubaan yang mungkin menjejaskan kualiti apabila didayakan. Dengan `True`, setiap pusingan prompting dihadkan kepada 1 penjanaan, menggantikan arahan bilangan imej dalam prompt dan mengabaikan imej perantaraan yang dijana model. |
| `enable_web_search` |  | boolean | no | `false` |  | Suis carian web untuk penjanaan imej, yang membolehkan model memasukkan maklumat terkini yang ditemui dalam talian ke dalam imej. |
| `thinking_level` |  | enum (string) \| null | no |  | `minimal`, `high` | Pilih 'minimal' atau 'high' untuk mengaktifkan pemikiran model pada tahap tersebut dan memasukkan pemikirannya dalam penjanaan; membiarkan tahap tidak ditetapkan memastikan pemikiran dilumpuhkan. |

File parameters (`images`, `video`, `audio`) 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": "Turn this night street scene into a sunny morning, keep the sneaker and the puddle reflections"
}
```

A fuller example:

```json
{
  "prompt": "Turn this night street scene into a sunny morning, keep the sneaker and the puddle reflections",
  "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-2/edit?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Turn this night street scene into a sunny morning, keep the sneaker and the puddle reflections",
    "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-2/edit?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "Turn this night street scene into a sunny morning, keep the sneaker and the puddle reflections",
    "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": "Turn this night street scene into a sunny morning, keep the sneaker and the puddle reflections",
    "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-2/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-2/edit",
      "input": {
        "prompt": "Turn this night street scene into a sunny morning, keep the sneaker and the puddle reflections",
        "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.
