# Nano Banana Lite Edit API

> Toleo Lite la Nano Banana kwa uhariri unaotegemea kidokezo wa picha moja au zaidi za ingizo

Huhariri au kubadilisha picha zilizotolewa katika `image_urls` kulingana na `prompt` inayohitajika yenye hadi vibambo 50000. Inaweza kurejesha picha 1 hadi 4 katika png, jpeg au webp, ikiwa na chaguo nyingi za `aspect_ratio` ikiwemo 8:1 na 1:8. `system_prompt` na `thinking_level` hutoa udhibiti wa ziada.

- Model id: `google/nano-banana-lite/edit`
- Made by: Google
- Category: Image Editing
- Output: image
- Estimated price per run: $0.043 / image (cheapest run $0.043 (43 API credits))
- Run: `POST https://api.doitong.com/v1/run/google/nano-banana-lite/edit`
- Quote: `POST https://api.doitong.com/v1/quote/google/nano-banana-lite/edit`
- Docs page: https://doitong.com/sw/developers/models/google/nano-banana-lite/edit

## Pricing

Price: **$0.043 / image**. Estimated from the typical cost of one run, per output (`num_images`). The quote is exactly what the run charges.

The full example input below costs $0.043 = 43 API credits (1 image × 43 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/google/nano-banana-lite/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 | Maelekezo ya maandishi ya kuhariri picha. |
| `system_prompt` |  | string | no | `` | ≤ 50000 characters | Mwongozo wa hiari wa persona na mtindo wa tokeo kwa ombi lote, unaowasilishwa kwa Gemini kama maagizo ya mfumo au kwa watoa huduma wanaoendana na OpenAI kama ujumbe wa mfumo. Hakuna kinachotumwa kwa maagizo haya thamani ikiwa tupu. |
| `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` | Uwiano wa picha ya tokeo, ukijumuisha chaguo kali 4:1, 1:4, 8:1, 1:8. |
| `image_urls` | `images` | array of image URL | no |  |  | URL zinazotambulisha picha chanzo za kuhariri au uzalishaji wa picha-kwa-picha. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Idadi ya picha iliyoombwa kwa uzalishaji. |
| `seed` |  | integer \| null | no |  |  | Thamani ya mbegu inayoanzisha uzalishaji wa nambari nasibu. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | Muundo wa faili wa picha inayotokana. |
| `safety_tolerance` |  | enum (string) | no | `4` | `1`, `2`, `3`, `4`, `5`, `6` | Weka ustahimilivu wa udhibiti wa maudhui kati ya kiwango kisicho na vizuizi zaidi, 6, na kiwango kikali zaidi, 1, kinachozuia maudhui mengi. |
| `limit_generations` |  | boolean | no | `true` |  | Kikomo cha majaribio cha uzalishaji ambacho kinaweza kuathiri ubora kinapowezeshwa. Kwa `True`, kila mzunguko wa uombaji huzuiwa kuwa uzalishaji 1, kikibatilisha maelekezo ya idadi ya picha kwenye kidokezo na kupuuza picha za kati zilizozalishwa na modeli. |
| `thinking_level` |  | enum (string) \| null | no |  | `minimal`, `high` | Chagua 'minimal' au 'high' ili kuwezesha fikra za modeli katika kiwango hicho na kujumuisha fikra zake kwenye uzalishaji; kuacha kiwango bila kuwekwa huweka fikra zimezimwa. |

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": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## 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/google/nano-banana-lite/edit?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

# 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/google/nano-banana-lite/edit?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
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": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/google/nano-banana-lite/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": "google/nano-banana-lite/edit",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.
