Easy API Management and Monitoring
Get Started Pricing Calculator Learn More
API Gateway is a service for convenient management and monitoring of APIs. The resources and methods related to APIs are simply defined to enable easy monitoring on API usage and performance index.

Features

  1. Convenient API Management

    Users can register and manage API with ease using a console, and managing access control is possible with an OAuth 2.0-based token. Being integrated with SCP Cloud Functions, users can also call Cloud Functions with API Gateway.

  2. Reliable Traffic Processing

    API Gateway can manage backend system traffic with usage planning and caching. With usage plans, users can set the maximum number of calls per hour (minute/hour/day/week/year), and with caching plans, users can specify the period where endpoint responses are cached. This ensures stable service operation by preventing excessive traffic.

  3. Easy Monitoring

    The service provides a range of management features including API version management for running APIs more reliably and a dashboard to see real-time usage. The performance indexes on API requests, response time and the number of errors can easily be monitored.

Pricing Standard

  • API Gateway is charged by the accumulated number of successful API calls.
  • Caching is charged based on the total amount of cache used per day, rounded up to the nearest MB. (e.g. If you use 3.7 MB of cache usage per day, you will be charged 4 MB)
  • Call counts and cache usage are accumulated and billed on a monthly basis.
