Engineering for Vibe Coders: API Design Basics

Description

If your API keeps changing every time you add a feature, you do not have a coding problem. You have a contract problem. Most prototypes design APIs reactively. A feature needs data, so a new endpoint appears. Then another. Soon naming is inconsistent, responses are unpredictable, and integrations become fragile. An API is not just an endpoint. It is a contract. Clear inputs. Consistent outputs. Predictable error handling. When that contract is stable, everything else becomes easier to build and extend. Before creating a new endpoint, ask yourself: is this consistent with my existing API pattern? That one habit turns quick prototypes into systems that scale without constant rewrites.
