1. API Description

Domain name for API request: cvm.intl.tencentcloudapi.com.

This API is used to query key pairs.

A key pair is a pair of keys generated by an algorithm in which the public key is available to the public and the private key is available only to the user. You can use this API to query the public key but not the private key.

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

We recommend you to use API Explorer

Try it

API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

2. Input Parameters

The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

Parameter Name	Required	Type	Description
Action	Yes	String	Common Params. The value used for this API: DescribeKeyPairs.
Version	Yes	String	Common Params. The value used for this API: 2017-03-12.
Region	Yes	String	Common Params. For more information, please see the list of regions supported by the product. This API only supports: ap-bangkok, ap-beijing, ap-chengdu, ap-chongqing, ap-guangzhou, ap-hongkong, ap-jakarta, ap-nanjing, ap-seoul, ap-shanghai, ap-shanghai-fsi, ap-shenzhen-fsi, ap-singapore, ap-tokyo, eu-frankfurt, na-ashburn, na-siliconvalley, sa-saopaulo.
KeyIds.N	No	Array of String	Key pair ID(s) in the format of `skey-11112222`. This API supports using multiple IDs as filters at the same time. For more information on the format of this parameter, see the `id.N` section in API Introduction. You cannot specify `KeyIds` and `Filters` at the same time. You can log in to the console to query the key pair IDs.
Filters.N	No	Array of Filter	Filters `project-id` - Integer - Optional - Filter by project ID. To view the list of project IDs, you can go to Project Management, or call the `DescribeProject` API and look for `projectId` in the response. `key-name` - String - Optional - Filter by key pair name. You cannot specify `KeyIds` and `Filters` at the same time.
Offset	No	Integer	Offset. The default value is `0`. For more information on `Offset`, see the relevant section in API Introduction.
Limit	No	Integer	Number of results returned; default value: 20; maximum: 100. For more information on `Limit`, see the corresponding section in API Introduction.

3. Output Parameters

Parameter Name	Type	Description
TotalCount	Integer	Number of key pairs meeting the filtering conditions.
KeyPairSet	Array of KeyPair	Detailed information on key pairs.
RequestId	String	The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem.

4. Example
