API Overview

API Introduction

BMS APIs (recommended) and Native OpenStack APIs are provided.

**Table 1** API description
Type	Function	Description
BMS APIs	API version information query	Query the API version of the BMS service.
	Lifecycle management	Create yearly/monthly BMSs and query BMS details.
	Status management	Change the BMS name, reinstall the BMS OS, start, restart, and stop BMSs.
	Flavor management	Query BMS flavor details and extended flavor information, such as the flavor ID, flavor name, number of CPUs, and boot device.
	NIC management	Query the BMS NIC information, such as the IP address and MAC address of the NIC.
	EVS disk management	Attach EVS disks to or detach EVS disks from a BMS, and query EVS disks attached to a BMS.
	Metadata management	The BMS metadata includes BMS basic information on the cloud platform, such as the BMS ID, hostname, and network information. You can update the BMS metadata.
	Tenant quota management	Query the quotas of all resources of a specified tenant, including used quotas.
	Password management	Query whether one-click password reset is supported. If yes, you can reset the BMS password. Obtain and delete the password of a Windows BMS.
	Task status query	After a task, such as creating a BMS or attaching disks, is delivered, job_id is returned, based on which you can query the execution status of the task.
Native OpenStack v2.1 APIs	Lifecycle management	Query BMS details, query BMSs, and query details about BMSs.
	Status management	Start, restart, and stop BMSs.
	Metadata management	The BMS metadata includes BMS basic information on the cloud platform, such as the BMS ID, hostname, and network information. You can query, update, and delete BMS metadata.
	IP address query	Query the private IP address of a BMS, including the IP address version (IPv4 or IPv6) and the specific IP address.
	BMS flavor query	Querying BMS Flavors: Query all BMS flavors or query specified BMS flavors by filters. Querying BMS Flavor Details: Query details about a BMS based on the flavor ID, such as the flavor name, number of CPUs, and memory. Querying Parameter extra_specs of a BMS Flavor: Parameter extra_specs specifies the key-value pair of a BMS flavor. If you want to check whether a BMS flavor supports quick provisioning, call this API.
	BMS NIC query	Query all NICs of a BMS or query details about a NIC based on the NIC ID, such as the IP address and MAC address of the NIC.
	EVS disk management	Query all EVS disks attached to a BMS or query details about an EVS disk attached to a BMS based on the disk ID, such as the mount directory.
	SSH key management	Query SSH key pairs or details about an SSH key pair, and create and delete SSH key pairs.
	1D tag management	Add, delete, modify, and query 1D tags of BMSs.

When using BMS APIs, you must use the endpoints of the BMS service.
When using native OpenStack APIs, you must use the endpoints registered by the ECS service.
In the current version, long HTTP connections cannot be used to call native OpenStack APIs.
