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 .
A maximum of 10 requests can be initiated per second for this API.

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.
