# Ideogram V4.5 API

> Chuyên gia kiểu chữ của Ideogram cho logo, áp phích và biển hiệu, với ba mức chất lượng.

Ideogram V4.5 là một trong những mô hình đáng tin cậy nhất cho chữ chính xác: logo, biển hiệu cửa hàng, áp phích và đồ họa mạng xã hội với từ ngữ được viết đúng. Chất lượng thấp, trung bình và cao đánh đổi tốc độ và giá để lấy chi tiết; kích thước hình ảnh không làm thay đổi giá. Có thể bật mở rộng lời nhắc, đặt seed và tạo tối đa tám hình ảnh mỗi yêu cầu.

- Model id: `ideogram/v4.5`
- Made by: Ideogram
- Category: Text to Image
- Output: image
- Price: from $0.03 / image (cheapest run $0.03 (30 API credits))
- Run: `POST https://api.doitong.com/v1/run/ideogram/v4.5`
- Quote: `POST https://api.doitong.com/v1/quote/ideogram/v4.5`
- Docs page: https://doitong.com/vi/developers/models/ideogram/v4.5

## Pricing

Price: **from $0.03 / image** (the lowest tier; the quote prices your exact input). Billed per generated image (`num_images`, default 1).

The full example input below costs $0.06 = 60 API credits (1 image × 60 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.com/v1/quote/ideogram/v4.5` 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 |  | 1 – 10000 characters | Lời nhắc mô tả quá trình tạo sinh hoặc chỉnh sửa. |
| `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` | Kích thước đầu ra có thể được chỉ định rõ ràng bằng một trong các kích thước được hỗ trợ sau: 1024x1024, 1024x3072, 1120x896, 1152x2944, 1152x864, 1248x3328, 1248x832, 1280x3072, 1280x720, 1280x800, 1296x3168, 1440x2560, 1440x2880, 1440x720, 1600x2560, 1664x2496, 1728x2304, 1792x2240, 2048x2048, 2240x1792, 2304x1728, 2496x1664, 2560x1440, 2560x1600, 2880x1440, 2944x1152, 3072x1024, 3072x1280, 3168x1296, 3328x1248, 720x1280, 720x1440, 800x1280, 832x1248, 864x1152, 896x1120. Đối với các giá trị đặt trước, 16:9 tương ứng với 1280x720 hoặc 720x1280, còn 4:3 tương ứng với 1152x864 hoặc 864x1152. Việc chọn square sẽ sử dụng square_hd ở 1024x1024. |
| `quality` |  | enum (string) | no | `medium` | `low`, `medium`, `high` | Thiết lập chất lượng cho việc tạo sinh văn bản thành hình ảnh. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Kiểm soát việc đối tác có mở rộng lời nhắc hay không. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 8 | Số hình ảnh cần tạo. |
| `seed` |  | integer \| null | no |  |  | Seed ngẫu nhiên, được chọn tự động khi bị bỏ qua. |

## Example input

Required parameters only:

```json
{
  "prompt": "A colorful storefront with a neon sign reading \"Night Owl Coffee\", rainy street reflections"
}
```

A fuller example:

```json
{
  "prompt": "A colorful storefront with a neon sign reading \"Night Owl Coffee\", rainy street reflections",
  "quality": "medium",
  "image_size": "landscape_4_3"
}
```

## 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/v4.5?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A colorful storefront with a neon sign reading \"Night Owl Coffee\", rainy street reflections",
    "quality": "medium",
    "image_size": "landscape_4_3"
  }'

# 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/v4.5?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A colorful storefront with a neon sign reading \"Night Owl Coffee\", rainy street reflections",
    "quality": "medium",
    "image_size": "landscape_4_3"
  }),
});
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 colorful storefront with a neon sign reading \"Night Owl Coffee\", rainy street reflections",
    "quality": "medium",
    "image_size": "landscape_4_3",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/ideogram/v4.5", 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/v4.5",
      "input": {
        "prompt": "A colorful storefront with a neon sign reading \"Night Owl Coffee\", rainy street reflections",
        "quality": "medium",
        "image_size": "landscape_4_3"
      },
      "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.
