# DescribeZoneAcceleratorConfigInfos

## 1. API Description

This API (DescribeZoneAcceleratorConfigInfos) is used to query the accelerator instance types available in an availability zone and their prices.

## 2. Input Parameters

The following request parameter list only provides API request parameters.

## 5. Developer Resources

Zenlayer Cloud API 2.0 integrates [SDKs](/api-reference/api-introduction/toolkit/api-sdk.md)，to make it easier for you to call APIs. More programming languages will be supported.

## 6. Error Codes

The following only lists the error codes related to the API business logic. For other error codes, see [Common Error Codes](/api-reference/api-introduction/instruction/commonerrorcode.md).
