Answer 1

You can use the Cloud Billing Catalog API, according to the official documentation:

• Get a list of all public SKUs within a service including:
  • Human readable description of the SKU.
  • Public pricing of the SKU.
  • Regions where the SKU is available for purchase.
  • Categorization data about the SKU.

An example:

Request:

GET https://cloudbilling.googleapis.com/v1/services/SERVICE_ID/skus?key=API_KEY

Where SERVICE_ID is the identifier of the parent service.

Response:

{
  "skus": [
    {
        "name": "[SKU_NAME]",
        "skuId": "[SKU_ID]",
        "description": "[SKU_DESCRIPTION]",
        "category": {
            "serviceDisplayName": "[SVC_DISPLAY_NAME]",
            "resourceFamily": "[FAMILY]",
            "resourceGroup": "[GROUP]",
            "usageType": "[USAGE]",
        },
        "serviceRegions": [
          "[REGION]"
        ],
        "pricingInfo": [
          {
              "effectiveTime": "[TIME]",
              "summary": "[SUMMARY]",
              "pricingExpression": {
                  "usageUnit": "[UNIT]",
                  "usageUnitDescription": "[UNIT_DESCRIPTION]",
                  "displayQuantity": [DISPLAY_QUANTITY],
                  "tieredRates": [
                    {
                        "startUsageAmount": [START_AMOUNT],
                        "unitPrice": {
                            "currencyCode": "[CURRENCY_CODE]",
                            "units": [UNITS],
                            "nanos": [NANOS],
                        },
                    }
                  ],
              },
              "aggregationInfo": {
                  "aggregationLevel": enum("[AGGREGATION_LEVEL]"),
                  "aggregationInterval": enum("[AGGREGATION_INTERVAL]"),
                  "aggregationCount": [AGGREGATION_COUNT],
              },
              "currencyConversionRate": [CONVERSION_RATE],
          }
        ],
        "serviceProviderName": "[SERVICE_PROVIDER]",
    }
  ]
}

According to your question, you would want to use these response objects:

• [UNIT] is the short hand for the unit of usage in which the pricing is specified. For example, usageUnit of GiBy means that usage is specified in "Gibibytes".
• [DISPLAY_QUANTITY] is the recommended quantity of units for displaying pricing info. When displaying pricing info, it is recommended to display: (unitPrice * displayQuantity) per displayQuantity usageUnit. This field does not affect the pricing formula and is for display purposes only. For example, if the unitPrice is "0.0001 USD", the usageUnit is "GB" and the displayQuantity is "1000", then the recommended way to display the pricing info is "0.10 USD per 1000 GB".
