1. API Description
Domain name for API request: vpc.tencentcloudapi.com.
This API (TransformAddress) is used to convert an ordinary public IP into an Elastic IP (EIP).
- The platform imposes a quota on the number of attempts to unbind an EIP and reallocate an ordinary public IP per day for each region (See Overview of EIP products). The above quota can be obtained through API DescribeAddressQuota.
A maximum of 10 requests can be initiated per second for this API.
Note: This API supports Finance regions. Since Finance regions and non-Finance regions are isolated and not interconnected. If the common parameter Region is a Finance region (such as ap-shanghai-fsi), you need to specify a domain name containing the Finance region that should be identical to the value of Region field, for example: vpc.ap-shanghai-fsi.tencentcloudapi.com.
