APIwiz

APIwiz is an API intelligence platform built for large and regulated enterprises managing complex, distributed API estates across multiple gateways, teams, and environments. At its core is the APIwiz Knowledge Graph, which connects business capabilities, applications, APIs, versions, endpoints, services, teams, consumers, gateways, databases, specifications, ownership, policies, security context, data, and runtime activity into a connected enterprise model. It captures not just what assets exist, but how they relate, what business capabilities they enable, who owns and consumes them, what depends on them, what controls apply, and how they behave in production. This creates a living layer of enterprise context that helps both teams and AI agents understand the API estate far beyond what a static catalog or point solution can provide. APIwiz brings this intelligence into API discovery, design, governance, security, testing, observability, developer experience, federation, and monetization—without requiring enterprises to replace their existing gateways or infrastructure. Built for regulated and API-intensive industries such as banking, financial services, insurance, telecommunications, and healthcare, APIwiz helps organizations reduce fragmentation, strengthen governance and security posture, accelerate delivery, and improve control across distributed API environments. As enterprises adopt AI agents and AI-driven applications, APIwiz provides the connected business and technical context AI systems need to understand what capabilities exist, which APIs enable them, how they are connected, who owns them, how they are used, and what policies and controls apply.
