    1. API Description

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

    This API (DescribeDBInstances) is used to query the list of TencentDB instances (which can be primary, disaster recovery, or read-only instances). It supports filtering instances by project ID, instance ID, access address, and instance status.

    A maximum of 100 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.
