Easy API Creation, Management, and Monitoring

API Gateway is a service for convenient creation, management, and monitoring of APIs. It can be defined resources and methods related to APIs in a consistent manner and applied built-in security access. It can also easily and conveniently monitor API usage status and performance indicators.

Overview

  • Fully Managed Service

    Users can easily create and manage APIs without having to set up or manage servers.

  • Scalability and Cost-effectiveness

    API Gateway handles hundreds of thousands of concurrent requests and operates cost-effectively with a usage-based pricing structure.

  • Strong Security

    Users can apply various security access methods provided, such as JWT token, IP access control, and API Key.(API Key will be provided in December 2025)
