A maximum of 20 requests can be initiated per second for this API.

Note: This API supports Finance regions. If the common parameter Region is a Finance region, a domain name with the Finance region needs to be specified, for example: as.ap-shanghai-fsi.tencentcloudapi.com

  • This value can be obtained from the ImageId field in the return value of the DescribeImages API.
  • ProjectId No Integer ID of the project to which the instance belongs. This parameter can be obtained from the projectId field in the returned values of DescribeProject. If this is left empty, default project is used.
    InstanceType No String Instance model. Different instance models specify different resource specifications. The specific value can be obtained by calling the DescribeInstanceTypeConfigs API to get the latest specification table or referring to the descriptions in Instance Types.
    InstanceType and InstanceTypes are mutually exclusive, and one and only one of them must be entered.
    SystemDisk No SystemDisk System disk configuration of the instance. If this parameter is not specified, the default value will be assigned to it.
    DataDisks.N No Array of DataDisk Information of the instance's data disk configuration. If this parameter is not specified, no data disk is purchased by default. Up to 11 data disks can be supported.

  • POSTPAID_BY_HOUR: Pay-as-you-go on an hourly basis

  • SPOTPAID: Bidding
  • InstanceMarketOptions No InstanceMarketOptionsRequest Market-related options of the instance, such as the parameters related to stop instances. If the billing method of instance is specified as bidding, this parameter must be passed in.
    InstanceTypes.N No Array of String List of instance models. Different instance models specify different resource specifications. Up to 10 instance models can be supported.
    InstanceType and InstanceTypes are mutually exclusive, and one and only one of them must be entered.
    InstanceTypesCheckPolicy No String Instance type verification policy. Value range: ALL, ANY. Default value: ANY.
