# 토큰 잔액 조회

> Query the remaining and used quota of the current API Key

> [!NOTE]
>
> **중국 본토 사용자 안내:** 중국 본토 사용자는 `https://toapis.cn` 를 API 엔드포인트(Base URL)로 사용해 주세요. 본 문서의 예시에서 `https://toapis.com` 을 `https://toapis.cn` 로 바꿔 주세요.

* Query the remaining and used quota of the current API Key
* Monitor single token usage
* CORS cross-origin support
* Real-time balance monitoring

Get the remaining and used balance of the current API Key (token). This endpoint is used to monitor the usage of a single token. Credit fields are also returned using the fixed conversion rate `1 USD = 200 credits`.

## Authorizations

**Authorization** `string` *required*

All endpoints require Bearer Token authentication

Get your API Key:

Visit the [API Key Management Page](https://toapis.com/console/token) to get your API Key

Add it to the request header:

```
Authorization: Bearer YOUR_API_KEY
```

## 엔드포인트s

```
GET /v1/balance
GET /balance
```

Both endpoints have the same functionality, you can use either one.

```bash cURL theme={null}
curl --request GET \
  --url 'https://toapis.com/v1/balance' \
  --header 'Authorization: Bearer <token>'
```

```python Python theme={null}

    response = requests.get(f'{API_BASE}/v1/balance', headers=headers)

## 응답

**success** `boolean`

Whether the request was successful

**message** `string`

오류 message (only returned on failure)

**remain\_balance** `float`

Token remaining balance (returned on success). Returns `-1` when `unlimited_quota` is `true`

**used\_balance** `float`

Token used balance (returned on success)

**remain\_credits** `float`

Token remaining credits (returned on success). Credits are calculated with `1 USD = 200 credits`

**used\_credits** `float`

Token used credits (returned on success)

**credits\_per\_usd** `float`

Credit conversion rate. Currently returns `200`

**unlimited\_quota** `boolean`

Whether the token has unlimited quota. `true` means unlimited, `false` means limited

## Use Cases

* Monitor consumption of a single API Key
* Display current token balance in your application
* Set up balance alerts when balance falls below threshold

> [!NOTE]
>
> **Balance Unit Information**
>
> The unit of the balance value depends on system configuration:
>
> * **USD** - US Dollars
> * **CNY** - Chinese Yuan
> * **Tokens** - Token count
>
> For stable integration, prefer `remain_credits` and `used_credits` when you need credit values. These fields always use `1 USD = 200 credits` and do not depend on the balance display configuration.

> [!TIP]
>
> **Unlimited Quota Token**
>
> When a token is set to unlimited quota:
>
> * `unlimited_quota` field returns `true`
> * `remain_balance` field returns `-1`
> * The token has no quota restrictions and can be used without limits

## Common 오류

| 오류 Message | Cause | Solution |
| - | - | - |
| No Authorization header | Authorization header not provided | Add `Authorization: Bearer sk-xxxxx` header |
| Failed to get token info | Token doesn't exist or has been deleted | Check if the token key is correct |

> [!WARNING]
>
> **Security Note**
>
> Your API Key is like a password. Keep it secure and don't share it with others. Always use HTTPS in production.
