# InquiryPriceChangeIpv6InternetChargeType

## 1. API Description

This API (InquiryPriceChangeIpv6InternetChargeType) is used to inquire the price after changing the IPv6 billing mode

{% hint style="info" %}
**Notes**

* When changing to bandwidth billing (`ByBandwidth`), `bandwidth` is required.
* When changing to traffic package billing (`ByTrafficPackage`), `flowPackage` is required (in TB, a multiple of 0.1 or 0).
* When changing to shared bandwidth package billing (`BandwidthCluster`), `clusterId` is required.
* The size of the guaranteed traffic package is only valid for billing periods of one month.
