# FLUX 2 Lora Gallery Hdr Style API

> Chuyển văn bản thành ảnh với phong cách siêu thực HDR và màu sắc mạnh, tự động thêm từ kích hoạt

Tạo hình ảnh siêu thực theo phong cách HDR từ `prompt` văn bản. Từ kích hoạt 'Hyp3rRe4list1c' được tự động thêm vào nên bạn không cần nhập. `lora_scale` (0 đến 2) kiểm soát cường độ diện mạo. Chọn trong sáu thiết lập sẵn về kích thước (mặc định landscape_4_3) và tạo 1 đến 4 hình ảnh.

- Model id: `flux-2-lora-gallery/hdr-style`
- Made by: Black Forest Labs
- Category: Text to Image
- Output: image
- Price: $0.021 / megapixel (cheapest run $0.021 (21 API credits))
- Run: `POST https://api.doitong.ru/v1/run/flux-2-lora-gallery/hdr-style`
- Quote: `POST https://api.doitong.ru/v1/quote/flux-2-lora-gallery/hdr-style`
- Docs page: https://doitong.com/vi/developers/models/flux-2-lora-gallery/hdr-style

## Pricing

Price: **$0.021 / megapixel**. Billed per megapixel of output (width × height of every image). Each image is rounded up to a whole megapixel.

The full example input below costs $0.021 = 21 API credits (1 MP × 21 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/flux-2-lora-gallery/hdr-style` 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 hình ảnh HDR tự động nhận 'Hyp3rRe4list1c' làm từ kích hoạt ở đầu. |
| `image_size` |  | object {width, height} \| enum (string) | no | `landscape_4_3` | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9` | Kích thước hình ảnh được tạo. |
| `guidance_scale` |  | number | no | `2.5` | 0 – 20 | Kiểm soát mức độ tuân thủ lời nhắc bằng scale CFG, trong đó CFG là viết tắt của Classifier Free Guidance. |
| `num_inference_steps` |  | integer | no | `40` | 4 – 50 | Số bước suy luận cần chạy. |
| `acceleration` |  | enum (string) | no | `regular` | `none`, `regular` | Thiết lập tăng tốc tạo sinh hình ảnh. Chọn 'regular' để cân bằng giữa tốc độ và chất lượng. |
| `seed` |  | integer \| null | no |  |  | Seed tạo sinh ngẫu nhiên cho phép tái tạo kết quả bằng cách giữ nguyên cả lời nhắc và seed. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Nút bật/tắt kiểm tra an toàn hình ảnh đã tạo; chỉ tài khoản được ủy quyền mới có thể tắt. Kiểm tra vẫn bắt buộc đối với các yêu cầu không có quyền ủy quyền. |
| `output_format` |  | enum (string) | no | `png` | `png`, `jpeg`, `webp` | Định dạng của hình ảnh kết quả. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Số hình ảnh cần tạo. |
| `lora_scale` |  | number | no | `1` | 0 – 2 | Cường độ hiệu ứng tạo kiểu HDR. |

## 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.ru/v1/run/flux-2-lora-gallery/hdr-style?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.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/flux-2-lora-gallery/hdr-style?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.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/flux-2-lora-gallery/hdr-style", 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": "flux-2-lora-gallery/hdr-style",
      "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.
