# Amazon API Gateway

**Website:** https://aws.amazon.com/api-gateway/  
**APIs profiled:** 13

Amazon API Gateway is a fully managed service that makes it easy to create, publish, maintain, monitor, and secure APIs at any scale. It acts as the front door for applications to access backend services, supporting REST APIs, HTTP APIs, and WebSocket APIs with built-in traffic management, authorization, monitoring, and API version management. API Gateway integrates natively with AWS Lambda, CloudWatch, CloudFront, IAM, and Cognito, and (as of December 2025) can expose REST APIs as MCP-compatible tools for Amazon Bedrock AgentCore Gateway for agent-driven API consumption.
