This talk addresses building a decentralized architecture that supports an agent economy by integrating APIs and AI gateways. We will discuss transitioning AI from an ad-hoc, shadow role to a core component of enterprise systems underpinned by federated governance over modular, cell-based structures. The session covers practical agent patterns and examines the roles of MCP, GraphQL, and knowledge bases using retrieval-augmented generation in creating robust, scalable systems.
