# Ideogram V4.0q [instant] API

> Biến thể chuyển văn bản thành ảnh nhanh nhất của Ideogram V4.0q, với chữ dễ đọc và bộ tham số tối giản

Mô hình chuyển văn bản thành hình ảnh tinh gọn dành cho áp phích, logo và thiết kế có chữ dễ đọc. Đầu vào chỉ gồm lời nhắc, `image_size` với sáu thiết lập sẵn, `num_images` từ 1 đến 4, `seed` và đầu ra jpeg hoặc png. `expansion_model` chỉ có thể là None hoặc Medium. Không hỗ trợ tùy chọn tốc độ kết xuất hoặc LoRA.

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

## Pricing

Price: **$0.0075 / megapixel of output image**. 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.

The full example input below costs $0.008 = 8 API credits (1 MP output image × $0.0075).

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/instant` 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` | Lựa chọn mở rộng lời nhắc, cung cấp mô hình magic lời nhắc nhanh qua 'Medium' hoặc không mở rộng qua 'None'. |
| `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. |
| `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/instant?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/instant?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/instant", 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/instant",
      "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.
