# InquiryPriceModifyUnmanagedEgressIpBandwidth

## 1. API Description

This API (InquiryPriceModifyUnmanagedEgressIpBandwidth) is used to inquire the price after adjusting the unmanaged egress IP bandwidth. The currently effective price of each billing item before the change is also returned through previousPrices, so that you can compare which billing items have price changes.

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

* Only unmanaged egress IPs billed by bandwidth (`ByBandwidth`) support this operation.
  {% endhint %}
