This talk will introduce Modus, an open source framework for building intelligent GraphQL APIs powered by WebAssembly. We will learn how Modus auto-generates GraphQL APIs inferred by user-defined types and uses WebAssembly to enable highly performant and scalable APIs that run in a sandboxed memory efficient environment. Modus also brings the power of open source AI models to the API developer with first class support for working with AI models. We will demo using Modus to build an agentic API capable of fetching data from multiple sources and analyzing the data in real-time using knowledge graph RAG to make decisions using LLM tool use.
