What FastAPI demand means in practice
FastAPI is a Python framework for building APIs with type-based validation and generated API documentation. It is used in service and model-integration work. Framework use should be read together with database, authentication and operating requirements in the vacancy.
Show request and response models, error behavior and authorization boundaries. Explain synchronous and asynchronous dependencies, tests and deployment. A credible service example includes load and failure behavior; generated API documentation is helpful, but it does not by itself prove correctness or production reliability.
