Build async FastAPI applications with async/await endpoints, background tasks, middleware, lifespan events, WebSockets, and streaming responses. Use when the user builds a FastAPI app, asks about async patterns, implements real-time features, or needs non-blocking I/O. Trigger when you see synchronous code in FastAPI that should be async.

Async FastAPI
Build high-performance async APIs with FastAPI. Async endpoints handle concurrent requests efficiently without blocking the event loop, which is critical for I/O-bound workloads like database queries, HTTP calls, and file operations.
When to Use
User creates or modifies FastAPI endpoints
User needs concurrent I/O operations
User implements WebSockets or streaming
User asks about background processing
User encounters event loop blocking or performance issues
