The rapid adoption of cloud computing, microservices, Internet of Things (IoT), and digital transformation initiatives has significantly increased enterprise dependence on Application Programming Interfaces (APIs) for secure communication and service integration. While APIs improve interoperability and operational efficiency, they also expand the attack surface, exposing enterprise systems to increasingly sophisticated cyber threats. Traditional perimeter-based security models are no longer sufficient to protect distributed enterprise environments where users, applications, and services operate across multiple networks and cloud platforms. This research proposes a Zero-Trust API Security Architecture integrated with Continuous Risk Intelligence to strengthen enterprise cybersecurity during digital transformation. The proposed framework adopts the Zero-Trust principle of "never trust, always verify" by continuously authenticating identities, validating API requests, monitoring behavioral patterns, and enforcing adaptive access control throughout the API lifecycle. Continuous Risk Intelligence employs artificial intelligence, behavioral analytics, threat intelligence, and real-time monitoring to identify evolving risks, detect anomalies, predict potential attacks, and automate security responses. The conceptual research methodology integrates Zero-Trust principles, API gateways, identity and access management, machine learning, and security orchestration into a unified enterprise architecture. The proposed framework enhances API confidentiality, integrity, availability, regulatory compliance, and operational resilience while reducing cyber risks associated with modern distributed computing environments. The study contributes to enterprise cybersecurity research by presenting an intelligent, adaptive, and scalable security architecture capable of protecting API ecosystems in cloud-native digital enterprises
