How pycodebr/car_api works

Car API is a FastAPI REST service for accounts, authentication, vehicle brands, and users’ cars. A client sends requests through the application’s registered routers; the handlers validate request and response data, apply domain rules, and use an async SQLAlchemy session to access persisted records. Authentication issues and refreshes JWTs, while protected operations resolve the current user. The README identifies SQLite as the database. The graph reflects sampled handlers and documented capabilities; unsampled settings and migration wiring are not inferred.
