# Omni Zero API

> Kết hợp các ảnh tham chiếu riêng về bố cục, phong cách và danh tính thành một hình ảnh mới

Trình tạo hình ảnh cách điệu cần `prompt` cùng bốn hình ảnh: `image_url`, `composition_image_url`, `style_image_url` và `identity_image_url`. Các giá trị cường độ riêng biệt (hình ảnh, composition, bản đồ độ sâu, phong cách, face và identity) cân bằng mức ảnh hưởng của chúng. Mô hình cũng cung cấp `negative_prompt`, `guidance_scale`, `seed` và `number_of_images`.

- Model id: `omni-zero`
- Made by: Open model
- Category: Image Editing
- Output: image
- Estimated price per run: $0.073 / image (cheapest run $0.073 (73 API credits))
- Run: `POST https://api.doitong.ru/v1/run/omni-zero`
- Quote: `POST https://api.doitong.ru/v1/quote/omni-zero`
- Docs page: https://doitong.com/vi/developers/models/omni-zero

## Pricing

Price: **$0.073 / image**. Estimated from the typical cost of one run, per output (`number_of_images`). The quote is exactly what the run charges.

The full example input below costs $0.073 = 73 API credits (1 image × 73 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/omni-zero` 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 |  |  | Lời nhắc định hướng việc tạo sinh hình ảnh. |
| `negative_prompt` |  | string | no | `` |  | Lời nhắc phủ định định hướng việc tạo sinh hình ảnh. |
| `image_url` | `image` | string (image URL) | yes |  |  | URL của hình ảnh đầu vào. |
| `composition_image_url` |  | string (image URL) | yes |  |  | URL của hình ảnh bố cục. |
| `style_image_url` |  | string (image URL) | yes |  |  | URL của hình ảnh phong cách. |
| `identity_image_url` |  | string (image URL) | yes |  |  | URL của hình ảnh nhận dạng. |
| `image_strength` |  | number | no | `0.75` |  | Mức độ ảnh hưởng của hình ảnh. |
| `composition_strength` |  | number | no | `1` |  | Mức độ ảnh hưởng của bố cục. |
| `depth_strength` |  | number | no | `0.5` |  | Mức độ ảnh hưởng của chiều sâu. |
| `style_strength` |  | number | no | `1` |  | Mức độ ảnh hưởng của phong cách. |
| `face_strength` |  | number | no | `1` |  | Mức độ ảnh hưởng của khuôn mặt. |
| `identity_strength` |  | number | no | `1` |  | Mức độ ảnh hưởng của nhận dạng. |
| `guidance_scale` |  | number | no | `5` |  | Tỷ lệ áp dụng cho hướng dẫn. |
| `seed` |  | integer | no | `42` |  | Seed cho bộ tạo ngẫu nhiên. |
| `number_of_images` |  | integer | no | `1` |  | Số lượng hình ảnh cần tạo. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Có thể nới lỏng việc kiểm duyệt bằng cách đặt thành false, nếu người gọi được cấp quyền. |

File parameters (`image`, `composition_image_url`, `style_image_url`, `identity_image_url`) 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",
  "composition_image_url": "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",
  "composition_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
  "style_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
  "identity_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/omni-zero?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",
    "composition_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "style_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "identity_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

```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/omni-zero?wait=20", {

### 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": "omni-zero",
      "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",
        "composition_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
        "style_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
        "identity_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.
