Querying the Price of a Pay-Per-Use Product

Function

Customers can query the price of a pay-per-use product by criteria on the self-built platform.

If the tenant who purchases the product enjoys a discount, the discount amount and the final price can be obtained from the query result.

If the tenant has enjoyed multiple types discounts, the system will return the commercial discount amount and the final price preferentially.

Ensure that you provide the correct service type, region, resource type, and resource specification. Otherwise, an error may be reported.
You can use the to determine product prices.
You can also use the price calculator to get the value of the product_infos request parameter when you call the API for querying product prices. For more details, see price inquiry examples.

Constraints

This API can be invoked using the AK/SK or token of the customer.

**Table 1** DemandProductInfo
Parameter	Mandatory	Type	Value Range	Description
id	Yes	String	A maximum of 64 characters	The ID is used to identify the mapping between the inquiry result and the request and must be unique in an inquiry.
cloud_service_type	Yes	String	A maximum of 400 characters	Cloud service type code. For example, the cloud service type code of OBS is hws.service.type.obs. To obtain a specific service type, call the API in Querying Cloud Service Types.
resource_type	Yes	String	A maximum of 400 characters	Resource type code. For example, the VM resource type code of ECS is hws.resource.type.vm. To obtain a specific resource type, call the API in Querying Resource Types. The relationship between ResourceType and CloudServiceType is as follows: A resource type represents a resource contained in the cloud service type, and the cloud service type is a combination of multiple resource types.
resource_spec	Yes	String	A maximum of 400 characters	Resource specifications. For details, see related cloud service documentation. The following provides examples of services and resource specifications: ECS Add .win or .linux to the end of the ECS flavor ID based on the OS type, for example, s2.small.1.linux. Call the API for querying details about flavors and extended flavor information to obtain the flavor IDs. Bandwidth 12_bgp: dynamic BGP bandwidth billed by traffic 12_sbgp: static BGP bandwidth billed by traffic 19_bgp: dynamic BGP bandwidth billed by bandwidth 19_sbgp: Static BGP bandwidth billed by bandwidth 19_share: Shared bandwidth billed by bandwidth IP address: 5_bgp: dynamic BGP public IP address 5_sbgp: static BGP public IP address EVS SATA: common I/O EVS disk SAS: high I/O EVS disk GPSSD: general-purpose SSD EVS disk SSD: ultra-high I/O EVS disk ESSD: Extreme SSD GPSSD2.storage: General-purpose SSD V2 storage GPSSD2.iops: General-purpose SSD V2 iops GPSSD2.throughput: General-purpose SSD V2 throughput
region	Yes	String	A maximum of 64 characters	Cloud service region code, for example, eu_west_101.
usage_factor	Yes	String	A maximum of 64 characters	Usage factor. Usage factors are case-insensitive. The value is the same as the usage factor value in the SDR. The mapping between cloud services and usage factors is as follows: Cloud server: Duration Cloud disk: Duration EIP: Duration Bandwidth: Duration or upflow Marketplace image: Duration You can call the API in Querying Usage Types to obtain the value of parameter code in Table 3. The value indicates the billing factor of each cloud service.
usage_value	Yes	BigDecimal	-	Usage value. For example, if you want to inquire a product price by hour, set usageValue to 1 and usageMeasureID to 4 (hour).
usage_measure_id	Yes	Integer	A maximum of 4 characters	Usage unit. You can call the API in Querying Measurement Units to obtain the value. For example, if you want to inquire a product price by hour, set usageValue to 1 and usageMeasureID to 4 (hour).

available_zone	No	String	A maximum of 64 characters	Available zone ID. Available zone IDs are case-insensitive. If this parameter is not included in the request parameters, is set to "", or is set to null, it cannot be used as a filter criterion.
resource_size	No	Integer	[1-214783647]	Resource capacity. It can be the subscribed volume size or bandwidth size. This parameter is mandatory for a linear product. Linear products are those whose size must be specified during a subscription, such as hard disks and bandwidth. For example, you can select 10 GB or 20 GB during a disk subscription. For non-linear products, if this parameter is not included in the request parameters or is set to null, it cannot be used as a filter criterion.
size_measure_id	No	Integer	A maximum of 4 characters	Resource capacity measurement ID. The options are: 15: Mbit/s (used when the bandwidth is subscribed) 17: GB (used when an EVS disk is subscribed to) 14: amount (times) This field should be filled together with resource_size or left blank. Linear products are those whose size must be specified during a subscription, such as hard disks and bandwidth. For example, you can select 10 GB or 20 GB during a disk subscription. For non-linear products, if this parameter is not included in the request parameters or is set to null, it cannot be used as a filter criterion.
