# Recraft V4 Styles Text to Vector API

> Tạo văn bản vector V4 tiêu chuẩn, áp dụng ID phong cách đã lưu hoặc hình ảnh tham chiếu nội tuyến

Tạo ảnh vector với kiểu nhất quán từ `style_id` đã lưu hoặc 1 đến 10 ảnh tham chiếu trong `image_urls`. `style_match` có thể là precise hoặc flexible. Nhận `prompt` dài tối đa 10.000 ký tự, giá trị đặt sẵn của `image_size`, `colors` và `background_color`. Trả về ảnh cùng kiểu đã dùng.

- Model id: `recraft/v4/style/text-to-vector`
- Made by: Recraft
- Category: Text to Image
- Output: image
- Price: from $0.05 / image (cheapest run $0.05 (50 API credits))
- Run: `POST https://api.doitong.com/v1/run/recraft/v4/style/text-to-vector`
- Quote: `POST https://api.doitong.com/v1/quote/recraft/v4/style/text-to-vector`
- Docs page: https://doitong.com/vi/developers/models/recraft/v4/style/text-to-vector

## Pricing

Price: **from $0.05 / image** (the lowest tier; the quote prices your exact input). Billed per generated image.

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `style_id` is not set: $0.055 (55 API credits) / image

The full example input below costs $0.055 = 55 API credits (1 image × 55 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/recraft/v4/style/text-to-vector` 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 |

| `colors` |  | array of object {r, g, b} | no | `[]` |  | Mảng chứa các màu ưu tiên. |
| `colors[].r` |  | integer | no | `0` | 0 – 255 | Giá trị của thành phần màu đỏ. |

| `background_color.b` |  | integer | no | `0` | 0 – 255 | Giá trị của thành phần màu xanh dương. |
| `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. |
| `style_id` |  | string \| null | no |  |  | Mã định danh cho phong cách tùy chỉnh V4 đã tạo trước đó. |
| `image_urls` | `images` | array of image URL \| null | no |  | 1 – 10 items | Cung cấp 1–10 tham chiếu phong cách bằng URL, sử dụng hình ảnh ở định dạng PNG, JPG hoặc WEBP. |
| `style_match` |  | enum (string) \| null | no |  | `precise`, `flexible` | Ghi đè mức độ bám theo phong cách tùy chỉnh trong quá trình tạo sinh. |

File parameters (`images`) 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"
}
```

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/recraft/v4/style/text-to-vector?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/recraft/v4/style/text-to-vector?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/recraft/v4/style/text-to-vector", 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": "recraft/v4/style/text-to-vector",
      "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.
