# Nano Banana 2 Edit API

> Eagarthóireacht thapa bunaithe ar threoracha a léann físeán, gearrthóg fuaime nó PDF mar chomhthéacs freisin.

Mód eagarthóireachta Nano Banana 2: cuir íomhánna ar aghaidh agus déan cur síos ar an athrú, nó fág na híomhánna ar lár agus tabhair físeán, comhad fuaime nó PDF (suas le 15 MB an ceann) mar chomhthéacs le léiriú. Aschur ó 0.5K go 4K le cóimheasa gné ó 1:8 go 8:1, cuardach roghnach gréasáin agus smaointeoireacht ard, suas le ceithre thoradh in aghaidh na hiarrata.

- 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/ga/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 | Treoracha téacs chun íomhá a chur in eagar. |

| `image_urls` | `images` | array of image URL | no |  |  | Soláthair íomhánna foinseacha de réir URL le haghaidh eagarthóireachta íomhá nó giniúna íomhá-go-íomhá, mura soláthraíonn tú ionchur malartach amháin ar a laghad: `video_url`, `audio_url`, nó `pdf_url`. |
| `system_prompt` |  | string | no | `` | ≤ 50000 characters | Treoir roghnach ar phearsa agus ar stíl aschuir ar fud an iarratais, a sheoltar chuig Gemini mar threoir chórais nó chuig soláthraithe comhoiriúnacha le OpenAI mar theachtaireacht chórais.

| `video_url` | `video` | string (video URL) \| null | no |  |  | Comhthéacs físeáin roghnach a sholáthraítear mar URL YouTube nó mar URL http(s)/data do chomhad físeáin. Sroicheann naisc YouTube an tsamhail go díreach gan íoslódáil; íoslódáiltear comhaid físeáin agus seoltar iad inlíne, faoi réir uasmhéid 15 MB. |
| `audio_url` | `audio` | string (audio URL) \| null | no |  |  | Soláthair comhthéacs fuaime roghnach trí URL http(s) nó data a dhíríonn chuig comhad nach mó ná 15 MB. Seoltar an comhad inlíne tar éis é a íoslódáil. |

Le `True`, cuirtear gach babhta leidithe teoranta do 1 ghiniúint, sáraítear treoracha líon na n-íomhánna sa leid agus déantar neamhaird d’íomhánna idirmheánacha a ghineann an tsamhail. |
| `enable_web_search` |  | boolean | no | `false` |  | Scorán cuardaigh ghréasáin le haghaidh giniúint íomhá, rud a ligeann don tsamhail faisnéis úr aimsithe ar líne a ionchorprú san íomhá. |
| `thinking_level` |  | enum (string) \| null | no |  | `minimal`, `high` | Roghnaigh 'minimal' nó 'high' chun smaointeoireacht na samhla a ghníomhachtú ag an leibhéal sin agus a smaointe a áireamh sa ghiniúint; má fhágtar an leibhéal gan socrú, fanann an smaointeoireacht díchumasaithe. |

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.
