This revolutionary API integrates seamlessly with any LLM, framework, or Message Control Plane (MCP) in as few as two lines of code, offering unparalleled ease of adoption. Developers can now ship rich, highly interactive AI applications up to 10 times faster, while simultaneously reducing UI overhead by an impressive 80%, accelerating innovation and enhancing user engagement.
