# 查看租户带宽限制 - ListBandwidthsLimit
#### 功能介绍
获取弹性公网IP带宽的限制列表，该接口用来查询当前租户下可购买的带宽计费类型及带宽上下限数据。
#### 调试
您可以在[API Explorer](https://console.huaweicloud.com/apiexplorer/#/openapi/EIP/doc?api=ListBandwidthsLimit&version=v3)中调试该接口，支持自动认证鉴权。
#### 授权信息
账号具备所有API的调用权限，如果使用账号下的IAM用户调用当前API，该IAM用户需具备调用API所需的权限。
- 如果使用角色与策略授权，具体权限要求请参见[权限和授权项](https://support.huaweicloud.com/api-eip/eip_apipermission_0000.html)。
- 如果使用身份策略授权，当前API调用无需身份策略权限。
