backend-api-endpoints

Design and implement RESTful API endpoints following REST principles, resource-based URL conventions, and HTTP method best practices. Use this skill when creating new API endpoints, defining routes or controllers, implementing REST resources, updating endpoint URL structures, working with HTTP method handlers (GET, POST, PUT, PATCH, DELETE), implementing API versioning, designing nested resource endpoints, adding query parameter support for filtering/sorting/pagination, setting up route middleware, implementing rate limiting headers, working with API routing configuration files, creating or updating API documentation, or refactoring endpoint structure for consistency. Use when working with Express.js routes, NestJS controllers, FastAPI endpoints, Django views, Rails controllers, or any backend framework's routing mechanisms.
