# 更新 API Key
> 更新当前组织下已有的用户 API Key。
## 概览
该接口用于更新已有用户 API Key 的名称、额度、模型白名单、过期时间或状态。
## 请求体
PATCH 请求至少需要提供一个字段。
| 字段 | 类型 | 默认值 / 限制 | 说明 |
| --------------- | -------------- | --------------------- | ----------------------------------------------------------- |
| `status` | enum | - | `active`, `inactive`, `revoked` |
| `name` | string | 长度 `1-50` | 更新后的展示名称 |
| `limitAmount` | number \| null | 最小 `0`，输入上限 `1000000` | `null` = 不限额，`0` = 零额度，正数会被规范化为一个存储上限，且不能超过 `100000` USD 等值 |
| `limitCurrency` | enum | 默认 `USD` | 仅支持 USD。发送 `CNY` 会返回 `400 currency_retired`。 |
| `models` | string\[] | - | 更新后的模型白名单 |
| `expiresAt` | string \| null | RFC3339 datetime | `null` 表示清除过期时间 |
## 说明
* Management API v1 故意不支持硬删除。
* `revoked` 更适合作为终态使用；如需恢复，通常建议新建一个 Key，而不是依赖后续“解封”流程。
## 示例
```bash cURL theme={null}
curl -X PATCH "https://api.tokenlab.sh/v1/management/api-keys/key_abc123def456" \
-H "Authorization: Bearer mt-your-management-token" \
-H "Content-Type: application/json" \
-d '{
"status": "inactive",
"limitAmount": 0
}'
```
