A company is building a RESTful serverless web application on AWS by using Amazon API...

An edge-optimized API endpoint is best for geographically distributed clients, as it routes the API requests to the nearest CloudFront Point of Presence (POP). This reduces the latency andimproves the performance of the API. Edge-optimized endpoints are the default type for API Gateway REST APIs1.

A regional API endpoint is intended for clients in the same region as the API, and it does not use CloudFront to route the requests. A private API endpoint is an API endpoint that can only be accessed from a VPC using an interface VPC endpoint. A regional or private endpoint would not meet the requirement of reducing the latency for geographically distributed users1.
