API-First
API-First is a software development methodology where APIs are treated as first-class citizens and designed before implementation begins. In an API-first approach, teams establish API contracts as the foundation of architecture, enabling parallel development, reusable services, consistent interfaces, and faster time-to-market. Organizations adopting API-first report 30-40% faster product releases (Gartner 2025) and significantly improved developer experience. The approach is foundational for microservices, headless architectures, and AI agent integrations.
