This document summarizes the development of an API for addresses in Go. It describes using Beego and pure Go for scalability. It implemented middlewares for routing, error handling, authentication, and logging. It also integrated New Relic for metrics. The API routes and controllers are chained through the middleware handlers. In conclusion, the API was able to successfully provide address functionality and insights through integration of middlewares and third-party services.
