From APIs to Capabilities – Reimagining Microservices for the Agentic Era

About this event

From APIs to Intent-Driven Capability Discovery for AI Agents As enterprises adopt AI agents, discovering the right API or tool for a user’s intent is becoming a key architectural challenge. In this session, Bageerathan Nadaraja Nadar, Software Architect at Walmart, explores the evolution from Microservices → APIs → Tools → MCP → Semantic Capabilities and how semantic discovery can help AI agents identify the right enterprise capability without overwhelming the LLM with hundreds of tools. The session includes a practical approach using AWS, Amazon Bedrock, vector embeddings, and MongoDB to build intent-driven capability discovery. Key takeaways: • Why traditional API discovery struggles in the Agentic Era • APIs vs. Tools vs. MCP • Semantic capability discovery • Using embeddings for intelligent tool selection • Building agent-ready enterprise services A practical look at moving from API discovery to intent-driven capability discovery.
