    Gateway instance fee

    Gateway instances support both pay-as-you-go and subscription billing methods. Each gateway instance includes a built-in Server Load Balancer (SLB), so you do not need to purchase an SLB separately.

    Note

    For more information about how to select a gateway instance type, see Capacity overview.

    Billing formulas

    • Pay-as-you-go (post-paid): Fee per instance = Unit price of the instance type × Hours of use.

      For example, if you run an apigw.small.x1 instance in the Chinese mainland region for 5 hours, the fee is USD 0.291 × 5 = USD 1.455.

    • Subscription (pre-paid): Fee per instance = Unit price of the instance type × Number of months.

      For example, if you subscribe to an apigw.small.x1 instance in the Chinese mainland region for one year, the fee is USD 147 × 12 = USD 1,764.

    Data processing fee

    When you create a gateway instance, you can select one of the following network types: Internet, VPC, or Internet + VPC. Data processed over different network types is billed separately. Within a billing cycle, the data processing volume is the total data volume of requests and responses.

    Network type

    Unit price (USD/GB/hour)

    Internet

    0.005

    VPC

    0.007

    Billing formulas

    • Internet: Hourly fee = Data processing volume × Unit price.

      For example, if you use a gateway instance for 2 hours and it processes 5 GB of data in the first hour and 10 GB in the second hour, the total data processing fee is (USD 0.005 × 5) + (USD 0.005 × 10) = USD 0.075.

    • VPC: Hourly fee = Data processing volume × Unit price.

      For example, if you use a gateway instance for 2 hours and it processes 5 GB of data in the first hour and 10 GB in the second hour, the total data processing fee is (USD 0.007 × 5) + (USD 0.007 × 10) = USD 0.105.

    Internet traffic fee

    Internet traffic is billed by Cloud Data Transfer (CDT). For more information, see Internet traffic pricing.
