Building APIs That Last: From Reactive Endpoints to Deliberate Design

This article reveals how poor API design emerges from reactive decision-making—treating each endpoint request in isolation rather than designing the API as a coherent whole. By introducing Claude Code as a conversation partner during design phases, the author demonstrates how intentional thinking prevents the inconsistencies, breaking changes, and naming problems that plague APIs six months after launch. The workflow is framework-agnostic and applies across REST, GraphQL, and gRPC, emphasizing that design discipline matters more than tooling.
