Module 1: API Paradigm Selection

REST, GraphQL, gRPC, and event-driven APIs each solve different problems. The paradigm selection is a load-bearing decision — choosing based on familiarity instead of requirements is the golden hammer anti-pattern wearing a protocol hat.

Module 2: Versioning & Evolution

APIs evolve. The versioning strategy determines whether that evolution is a smooth migration or a synchronized fire drill across every consumer.

Module 3: Operational API Design

Rate limiting, error handling, and observability are not afterthoughts. They are design decisions that determine whether the API is production-grade or demo-grade.
