# Nano Banana 2 Edit API

> Snelle bewerking op basis van instructies, waarbij ook een video, audioclip of PDF als context kan worden gelezen.

De bewerkingsmodus van Nano Banana 2: geef afbeeldingen door en beschrijf de wijziging, of sla afbeeldingen over en geef een video, audiobestand of PDF (elk maximaal 15 MB) als context om te illustreren. Uitvoer van 0.5K tot 4K met beeldverhoudingen van 1:8 tot 8:1, optioneel zoeken op het web en hoog denkvermogen, maximaal vier resultaten per request.

- 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.ru/v1/run/nano-banana-2/edit`
- Quote: `POST https://api.doitong.ru/v1/quote/nano-banana-2/edit`
- Docs page: https://doitong.com/nl/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.ru/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 | Tekstinstructies voor het bewerken van een afbeelding. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Aantal afbeeldingen dat voor generatie wordt aangevraagd. |
| `seed` |  | integer \| null | no |  |  | Seedwaarde die de generatie van willekeurige getallen initialiseert. |
| `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` | Beeldverhouding van de uitvoerafbeelding, inclusief de extreme opties 4:1, 1:4, 8:1 en 1:8. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | Bestandsindeling van de resulterende afbeelding. |
| `safety_tolerance` |  | enum (string) | no | `4` | `1`, `2`, `3`, `4`, `5`, `6` | Stel de tolerantie voor contentmoderatie in tussen het minst beperkende niveau, 6, en het strengste niveau, 1, dat de meeste inhoud blokkeert. |
| `image_urls` | `images` | array of image URL | no |  |  | Lever bronafbeeldingen aan via URL voor afbeeldingsbewerking of image-to-image-generatie, tenzij je minstens één alternatief invoeritem opgeeft: `video_url`, `audio_url` of `pdf_url`. |
| `system_prompt` |  | string | no | `` | ≤ 50000 characters | Optionele persona- en uitvoerstijlbegeleiding voor de hele request, als systeeminstructie aan Gemini of als systeembericht aan OpenAI-compatibele providers. Bij een lege waarde wordt niets voor deze instructie verzonden. |
| `resolution` |  | enum (string) | no | `1K` | `0.5K`, `1K`, `2K`, `4K` | Resolutie van de uitvoerafbeelding. |
| `video_url` | `video` | string (video URL) \| null | no |  |  | Optionele videocontext als YouTube-URL of http(s)/data-URL voor een videobestand. YouTube-links bereiken het model rechtstreeks zonder download; videobestanden worden gedownload en inline verzonden, met een maximum van 15 MB. |
| `audio_url` | `audio` | string (audio URL) \| null | no |  |  | Lever optionele audiocontext aan via een http(s)- of data-URL naar een bestand van maximaal 15 MB. Het bestand wordt na het downloaden inline verzonden. |
| `pdf_url` |  | string \| null | no |  |  | Lever optionele PDF-context aan via een http(s)- of data-URL naar een document van maximaal 15 MB. Het document wordt na het downloaden inline verzonden. |
| `limit_generations` |  | boolean | no | `true` |  | Experimentele generatiebeperking die bij inschakeling de kwaliteit kan beïnvloeden. Met `True` wordt elke promptingsronde beperkt tot 1 generatie, worden afbeeldingsaantallen in de prompt overschreven en door het model gegenereerde tussenafbeeldingen genegeerd. |
| `enable_web_search` |  | boolean | no | `false` |  | Schakelaar voor webzoeken bij afbeeldingsgeneratie, waarmee het model actuele online informatie in de afbeelding kan verwerken. |
| `thinking_level` |  | enum (string) \| null | no |  | `minimal`, `high` | Selecteer 'minimal' of 'high' om het modeldenken op dat niveau te activeren en de gedachten in de generatie op te nemen; als je het niveau niet instelt, blijft denken uitgeschakeld. |

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.ru/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.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

  "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);

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.ru/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.ru/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.
