Querying Instances and Details

Function

This API is used to query instances and details based on specified conditions.

Constraints

This API supports GeminiDB Cassandra instances.

URI

GET https://{Endpoint}/v3/{project_id}/instances

**Table 1** Path parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID of a tenant in a region. To obtain this value, see Obtaining a Project ID.

**Table 2** Query parameters
Parameter	Mandatory	Type	Description
id	No	String	Instance ID. If you enter an instance ID starting with an asterisk (*), fuzzy search results are returned. If you enter a valid instance ID, an exact result is returned.
name	No	String	Instance name. If you enter an instance name starting with an asterisk (*), fuzzy search results are returned. If you enter a valid instance name, an exact result is returned.
datastore_type	No	String	Database type. The value can be: cassandra, indicating that GeminiDB Cassandra instances are queried.
mode	No	String	Instance type. The value can be: Cluster, indicating that GeminiDB Cassandra cluster instances are queried. The system ignores this parameter if parameter datastore_type is not transferred.
vpc_id	No	String	VPC ID. You can obtain the value with either of the following methods: Method 1: Log in to the VPC console and view the VPC ID on the VPC details page. Method 2: See section "Querying VPCs" in the Virtual Private Cloud API Reference.
subnet_id	No	String	Subnet ID. You can obtain the subnet ID with either of the following methods: Method 1: Log in to the VPC console and click the target subnet on the Subnets page. You can view the network ID on the displayed page. Method 2: See section "Querying Subnets" in the Virtual Private Cloud API Reference.
offset	No	Integer	Index position. The query starts from the next instance creation time indexed by this parameter under a specified project. If offset is set to N, the resource query starts from the N+1 piece of data. The value must be no less than 0. If this parameter is not transferred, the index offset is 0 by default, indicating that the query starts from the latest created instance.
limit	No	Integer	Maximum number of instances that can be queried. The value ranges from 1 to 100. If this parameter is not transferred, the first 100 instances are queried by default.

Request Parameters

**Table 3** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	User token.
