Stop Building REST APIs for AI Agents (Use JSON-RPC)

Hey DEV community, CallmeMiho here. I’ve been auditing backend architectures all week, and the amount of money being burned on "AI integration" is staggering. If you are still trying to force your AI agents to navigate hypermedia-driven REST APIs, you aren't an architect; you're a museum curator. Let's talk about why the entire industry is moving back to a 20-year-old protocol. We spent the last decade arguing over REST maturity models and GraphQL schema stitching, only to find out that the autonomous agents of 2026 don't care about HTTP verbs. They care about executing functions.
