Design and implement RESTful API endpoints following REST principles with proper HTTP methods, status codes, resource-based URLs, and rate limiting. Use this skill when creating or modifying API endpoints, route handlers, controllers, or any backend API layer code. Apply when working on files that define API routes (routes/*.ts, controllers/*.ts, api/*.ts, *Controller.cs), implement request/response handlers, establish API versioning, or configure endpoint middleware. Use when building Bun/Express APIs, ASP.NET Core Web APIs, or Next.js API routes. This skill ensures RESTful design with clear resource-based URLs, consistent lowercase hyphenated naming, appropriate HTTP methods (GET, POST, PUT, PATCH, DELETE), proper status codes (200, 201, 400, 404, 500), plural nouns for resources (/users, /products), limited nesting depth (2-3 levels max), query parameters for filtering/sorting/pagination, API versioning strategies, and rate limiting headers in responses.
