About

Amazon API Gateway is a fully managed service for creating, publishing, maintaining, monitoring, and securing APIs at scale. It provides a front door for applications to access data, business logic, and backend functionality through REST APIs, HTTP APIs, and WebSocket APIs.

The service is designed for teams building serverless, containerized, and web application backends that need reliable API management with built-in traffic control, authorization, monitoring, and versioning. It also includes API Gateway Portals for creating AWS-native developer portals to discover, document, and govern APIs across an organization.

  • Build and manage REST, HTTP, and WebSocket APIs
  • Support real-time two-way communication for interactive applications
  • Apply traffic management, throttling, CORS, and access control
  • Integrate with IAM, Amazon Cognito, OIDC, OAuth2, and Lambda authorizers
  • Monitor API activity and performance with CloudWatch
  • Create managed developer portals for API discovery and governance

Free Tier Value

Feature parity 100%

This is an intro_tier free offer: the page says the free tier includes 1M REST API calls, 1M HTTP API calls, 1M WebSocket messages, and 750,000 connection minutes per month for up to 12 months, only for new AWS customers. Because the free tier is capped and time-limited, the conservative monthly FTV is computed from the included quotas, but the page does not provide enough pricing detail here to safely price all included components into a single monthly value without over-assuming usage mix, so I set free_tier_value_usd_per_month to null. The page also states new AWS customers receive up to $200 in AWS Free Tier credits starting July 15, 2025, so free_credit_amount_usd is 200; no explicit no-CC requirement is stated.
