1. API Description

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

This API is used to create one or more instances with a specified configuration.

• After an instance is created successfully, it will start up automatically, and the instance state will become "Running".
• If you create a pay-as-you-go instance billed on an hourly basis, an amount equivalent to the hourly rate will be frozen before the creation. Make sure your account balance is sufficient before calling this API.
• The number of instances you can purchase through this API is subject to the CVM instance purchase limit. Both the instances created through this API and the console will be counted toward the quota.
• This API is an async API. An instance ID list will be returned after you successfully make a creation request. However, it does not mean the creation has been completed. The state of the instance will be Creating during the creation. You can use DescribeInstances to query the status of the instance. If the status changes from Creating to Running, it means that the instance has been created successfully.

A maximum of 10 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: cvm.ap-shanghai-fsi.tencentcloudapi.com
