What types of APIs can Amazon API Gateway create?
Amazon API Gateway supports REST APIs, HTTP APIs, and WebSocket APIs. REST APIs offer the broadest management features, while HTTP APIs are designed as a simpler and often lower-cost option.

Yes, API Gateway can invoke AWS Lambda functions when an HTTP request reaches a configured route. It can also connect to services such as Amazon ECS, EC2 applications, and external HTTPS endpoints.
How is API Gateway priced?
Pricing is based mainly on API requests and data transferred, with different rates for REST, HTTP, and WebSocket APIs. The total bill can also include Lambda, data transfer, logging, and other AWS services used behind the API.
Can API Gateway protect an API from abuse?
