# Nano Banana 2 Edit API

> Pengeditan cepat berbasis instruksi yang juga dapat membaca video, klip audio atau PDF sebagai konteks.

Mode pengeditan Nano Banana 2: berikan gambar dan jelaskan perubahannya, atau lewati gambar dan berikan video, file audio, atau PDF (masing-masing hingga 15 MB) sebagai konteks untuk ilustrasi. Output dari 0.5K hingga 4K dengan rasio aspek dari 1:8 hingga 8:1, pencarian web dan pemikiran tinggi opsional, hingga empat hasil per permintaan.

## 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 |

| `image_urls` | `images` | array of image URL | no |  |  | Berikan gambar sumber melalui URL untuk pengeditan gambar atau pembuatan image-to-image, kecuali Anda memberikan setidaknya satu input alternatif: `video_url`, `audio_url`, atau `pdf_url`. |
| `system_prompt` |  | string | no | `` | ≤ 50000 characters | Panduan persona dan gaya output opsional untuk seluruh permintaan, dikirim ke Gemini sebagai instruksi sistem atau ke penyedia yang kompatibel dengan OpenAI sebagai pesan sistem. Tidak ada yang dikirim untuk instruksi ini jika nilainya kosong. |
| `resolution` |  | enum (string) | no | `1K` | `0.5K`, `1K`, `2K`, `4K` | Resolusi gambar output. |
| `video_url` | `video` | string (video URL) \| null | no |  |  | Konteks video opsional yang diberikan sebagai URL YouTube atau URL http(s)/data untuk file video. Tautan YouTube diteruskan langsung ke model tanpa diunduh; file video diunduh dan dikirim inline, dengan batas maksimum 15 MB. |

| `limit_generations` |  | boolean | no | `true` |  | Batas pembuatan eksperimental yang dapat memengaruhi kualitas saat diaktifkan. Dengan `True`, setiap putaran prompting dibatasi menjadi 1 pembuatan, mengganti instruksi jumlah gambar dalam prompt dan mengabaikan gambar antara yang dibuat model. |
| `enable_web_search` |  | boolean | no | `false` |  | Sakelar pencarian web untuk pembuatan gambar, yang memungkinkan model memasukkan informasi terbaru dari internet ke dalam gambar. |
| `thinking_level` |  | enum (string) \| null | no |  | `minimal`, `high` | Pilih 'minimal' atau 'high' untuk mengaktifkan pemikiran model pada tingkat tersebut dan menyertakan pemikirannya dalam pembuatan; jika tingkat tidak disetel, pemikiran tetap dinonaktifkan. |

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.
