# Gemini 3 Pro Image Preview · Edit API

> Uhariri wa picha wa Gemini 3 Pro Image kutoka kwenye picha za marejeleo, ukiwa na matokeo ya 1K hadi 4K na chaguo la utafutaji wa wavuti

Huhariri au kuunganisha upya picha kutoka kwenye `image_urls` (inahitajika) kulingana na `prompt`. `aspect_ratio` huwa auto kwa chaguomsingi, `resolution` inaweza kuwa 1K, 2K au 4K, na `system_prompt` pamoja na utafutaji wa wavuti vinaweza kuwezeshwa. Hurudisha picha 1 hadi 4 zilizohaririwa katika PNG, JPEG au WebP.

- Model id: `gemini-3-pro-image-preview/edit`
- Made by: Google
- Category: Image Editing
- Output: image
- Price: from $0.15 / image (cheapest run $0.15 (150 API credits))
- Run: `POST https://api.doitong.ru/v1/run/gemini-3-pro-image-preview/edit`
- Quote: `POST https://api.doitong.ru/v1/quote/gemini-3-pro-image-preview/edit`
- Docs page: https://doitong.com/sw/developers/models/gemini-3-pro-image-preview/edit

## Pricing

Price: **from $0.15 / 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 `resolution` = 4K: $0.30 (300 API credits) / image

The full example input below costs $0.15 = 150 API credits (1 image × 150 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/gemini-3-pro-image-preview/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.

| `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. |
| `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` | Uwiano wa picha inayotokana. |
| `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. |
| `image_urls` | `images` | array of image URL | yes |  |  | URL zinazotambulisha picha chanzo za kuhariri au uzalishaji wa picha-kwa-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. |
| `resolution` |  | enum (string) | no | `1K` | `1K`, `2K`, `4K` | Mwonekano wa picha ya tokeo. |
| `limit_generations` |  | boolean | no | `true` |  | Kikomo cha majaribio cha uzalishaji: kuwezesha `True` hubatilisha maelekezo yoyote ya idadi ya picha kwenye kidokezo na kuzuia kila mzunguko wa uombaji kuwa uzalishaji 1. |
| `enable_web_search` |  | boolean | no | `false` |  | Kigeuzi cha utafutaji wa wavuti kwa uzalishaji wa picha, kinachoruhusu modeli kujumuisha maelezo ya kisasa yanayopatikana mtandaoni kwenye picha. |

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",
  "images": [
    "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "image_urls": [
    "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  ]
}
```

## 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/gemini-3-pro-image-preview/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",
    "image_urls": [
      "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
    ]
  }'

# 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",
};

### Python

```python
import os
import requests

API = "https://api.doitong.ru/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/gemini-3-pro-image-preview/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": "gemini-3-pro-image-preview/edit",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "image_urls": [
          "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
        ]
      },
      "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.
