      1. API Description

      Domain name for API request: lighthouse.tencentcloudapi.com.

      This API is used to unbind an instance from the specified key pair.

      • Only instances on LINUX_UNIX in [RUNNING, STOPPED] status are supported. Instances in RUNNING status will be forcibly shut down before unbinding.
      • After a key pair is unassociated from an instance, you can log in to the instance with password.
      • If no password was set, you cannot log in to the instance with SSH after unbinding. You can call the ResetInstancesPassword API to set a login password.
      • Batch operations are supported. The maximum number of instances in each request is 100.
      • This API is async. After the request is sent successfully, a RequestId will be returned. At this time, the operation is not completed immediately. The result of the instance operation can be queried by calling the DescribeInstances API. If the latest operation status (LatestOperationState) of the instance is SUCCESS, the operation is successful.

      A maximum of 20 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.
