For 15 years the API has been the non-negotiable contract between systems. You want data, you call an endpoint. You want an action, you send a request. That contract is now being renegotiated without anyone asking your permission. Gartner projects that 40% of enterprise applications will embed AI agents by end of 2026, up from 5% in 2025. Those agents do not always call your APIs. They use MCP servers that discover capabilities dynamically, computer use models that operate UIs directly without touching your endpoints, and A2A protocols that let agents delegate to other agents without a single REST call in the chain. The per-seat SaaS model, the REST integration contract, and the API gateway as the system of record all three are being disrupted simultaneously and most architecture teams have not started the conversation yet.

This session is that conversation. We will walk through what the new agent-first integration stack actually looks like, where REST and GraphQL still win, where MCP replaces them, and where computer use agents bypass both entirely.

You will leave with a concrete architectural decision framework for building systems in 2026 that serve human users, AI agents, and everything in between without rebuilding your integration layer from scratch every six months.
