# Ideogram V4.0q Image to Image LoRA API

> Перестилизация обязательного входного изображения с применением до 3 LoRA и сохранением композиции, с настраиваемой силой влияния

Принимает обязательный `image_url` и промпт, затем применяет пользовательские веса LoRA (`loras`, максимум 3) для управления стилем, объектом или внешним видом бренда. `strength` от 0 до 1 задаёт степень отклонения результата от источника; 1.0 игнорирует его. `image_size` по умолчанию равен `auto` и соответствует входным данным. Создаёт 1-4 изображения в формате jpeg или png.

- Model id: `ideogram/v4/image-to-image/lora`
- Made by: Ideogram
- Category: Image Editing
- Output: image
- Price per megapixel of your output image: from $0.0113 / megapixel of output image (cheapest run $0.012 (12 API credits))
- Run: `POST https://api.doitong.ru/v1/run/ideogram/v4/image-to-image/lora`
- Quote: `POST https://api.doitong.ru/v1/quote/ideogram/v4/image-to-image/lora`
- Docs page: https://doitong.ru/ru/developers/models/ideogram/v4/image-to-image/lora

## Pricing

Price: **from $0.0113 / megapixel of output image** (the lowest tier; the quote prices your exact input). Price per megapixel of your output image: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

Price by tier:

- TURBO: $0.0113 / megapixel of output image
- BALANCED: $0.0225 / megapixel of output image
- QUALITY: $0.0375 / megapixel of output image

The full example input below costs $0.023 = 23 API credits (1 MP output image × $0.0225 (BALANCED)).

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/ideogram/v4/image-to-image/lora` 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 |  |  | Промпт, управляющий генерацией изображения. |
| `expansion_model` |  | enum (string) | no | `Medium` | `None`, `Medium`, `Large` | Выберите модель расширения промпта: 'Large' обеспечивает самое высокое качество с помощью Magic Prompt от Ideogram, а 'Medium' отдаёт приоритет скорости. Выберите 'None', чтобы не расширять промпт. |
| `image_size` |  | object {width, height} \| enum (string) | no | `auto` | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9`, `auto` | Задайте размеры выходных данных или выберите 'auto', чтобы сохранить размеры входных данных в пределах следующих ограничений: около 25MP суммарно и не более 8192px по каждой стороне. |
| `rendering_speed` |  | enum (string) | no | `BALANCED` | `TURBO`, `BALANCED`, `QUALITY` | Настройка скорости рендеринга; более быстрые варианты выполняют меньше шагов устранения шума. |
| `acceleration` |  | enum (string) | no | `none` | `none`, `low`, `regular`, `high` | Настройка ускорения генерации изображений. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Количество создаваемых изображений. |
| `seed` |  | integer \| null | no |  |  | Начальное значение генерации, выбираемое случайно, если значение не указано. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Переключатель проверки безопасности, отключение которого требует авторизации учётной записи. Без такой авторизации каждый запрос проверяется независимо от настройки; значение true включает проверку. |
| `output_format` |  | enum (string) | no | `jpeg` | `jpeg`, `png` | Формат файла итогового изображения. |
| `image_url` | `image` | string (image URL) | yes |  |  | URL исходного изображения для генерации изображения на основе изображения. |
| `strength` |  | number | no | `0.8` | 0 – 1 | Степень преобразования изображения: меньшие значения сохраняют результат ближе к исходному, а при 1.0 исходное изображение не влияет на результат. |
| `loras` |  | array of object {path, scale} | no | `[]` | ≤ 3 items | Веса LoRA для применения; ограничение — 3 записи. |
| `loras[].path` |  | string | yes |  |  | URL файла .safetensors, содержащего веса LoRA Ideogram V4. |
| `loras[].scale` |  | number | no | `1` | 0 – 4 | Множитель, применяемый к весам LoRA. |

File parameters (`image`) 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",
  "image": "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_url": "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/ideogram/v4/image-to-image/lora?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_url": "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

const API = "https://api.doitong.ru/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/ideogram/v4/image-to-image/lora?wait=20", {

  }),
});
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.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",
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/ideogram/v4/image-to-image/lora", 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": "ideogram/v4/image-to-image/lora",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "image_url": "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.
