The request asks what to use to add a web handler endpoint. Several web frameworks let you register a route and handler directly: Actix Web provides route macros and handlers for Rust 2, Litestar offers @get route handlers in Python 6, Starlette is a lightweight ASGI toolkit with routing 8, and Drogon exposes registerHandler for C++ 9. For guidance on writing ASP.NET Core endpoints with OpenAPI metadata, the Microsoft dotnet-webapi and aspnet-minimal-api-openapi actions apply 311.
