# Ideogram V4.0 Text to Image API

> Ideogram V4 chuyển văn bản thành hình ảnh với mở rộng lời nhắc, tốc độ và tăng tốc có thể chọn, tối đa 4 hình ảnh

Tạo hình ảnh từ `prompt`. `expansion_model` có thể là None, Medium hoặc Large, còn `rendering_speed` là TURBO, BALANCED hoặc QUALITY, với thiết lập `acceleration` bổ sung từ none đến high. Trả về 1 đến 4 hình ảnh ở định dạng JPEG hoặc PNG với các thiết lập sẵn kích thước. Đây là tùy chọn chuyển văn bản thành hình ảnh V4 đầy đủ tính năng nhất.

- Model id: `ideogram/v4`
- Made by: Ideogram
- Category: Text to Image
- Output: image
- Price per megapixel of your output image: from $0.0075 / megapixel of output image (cheapest run $0.008 (8 API credits))
- Run: `POST https://api.doitong.com/v1/run/ideogram/v4`
- Quote: `POST https://api.doitong.com/v1/quote/ideogram/v4`
- Docs page: https://doitong.com/vi/developers/models/ideogram/v4

## Pricing

Price: **from $0.0075 / 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: $0.0075 / megapixel of output image
- BALANCED: $0.015 / megapixel of output image
- QUALITY: $0.025 / megapixel of output image

The full example input below costs $0.015 = 15 API credits (1 MP output image × $0.015 (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.com/v1/quote/ideogram/v4` 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. |
| `expansion_model` |  | enum (string) | no | `Medium` | `None`, `Medium`, `Large` | Chọn mô hình mở rộng lời nhắc: 'Large' cung cấp chất lượng cao nhất thông qua Magic Prompt của Ideogram, còn 'Medium' ưu tiên tốc độ. Chọn 'None' để giữ nguyên lời nhắc không mở rộng. |
| `image_size` |  | object {width, height} \| enum (string) | no | `square_hd` | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9` | Độ phân giải của hình ảnh đang được tạo. |
| `rendering_speed` |  | enum (string) | no | `BALANCED` | `TURBO`, `BALANCED`, `QUALITY` | Thiết lập tốc độ kết xuất; các tùy chọn nhanh hơn thực hiện ít bước khử nhiễu hơn. |
| `acceleration` |  | enum (string) | no | `none` | `none`, `low`, `regular`, `high` | Thiết lập tăng tốc khi tạo sinh hình ảnh. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Số hình ảnh cần tạo. |
| `seed` |  | integer \| null | no |  |  | Seed cho việc tạo sinh, được chọn ngẫu nhiên trừ khi bạn cung cấp giá trị. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Công tắc kiểm tra an toàn, trong đó trạng thái tắt yêu cầu ủy quyền tài khoản. Nếu không có ủy quyền, mọi yêu cầu đều được kiểm tra bất kể cài đặt; true bật trình kiểm tra. |
| `output_format` |  | enum (string) | no | `jpeg` | `jpeg`, `png` | Định dạng tệp của hình ảnh kết quả. |

## 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/ideogram/v4?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/ideogram/v4?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/ideogram/v4", 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": "ideogram/v4",
      "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.
