When AI Agents Pay and Sellers Monetize: Building x402 Apps for Agentic Commerce on AWS

Official Schedule Context

As Agentic AI moves from chat to execution, autonomous agents need a native way to discover, access,

and pay for digital services in real time. This session explores how x402 can turn HTTP into a

payment-aware interface for machine-to-machine commerce, unlocking crypto-native patterns like

programmable access, pay-per-use APIs, and on-demand monetization for data, tools, and services.

We’ll show how to build x402-enabled applications and walk through the architecture, the full

agentic payments flow, seller monetization strategies, payment verification, and design tradeoffs

involved in making agent-driven transactions secure, scalable, and production-ready. Attendees will

leave with practical patterns for building apps where AI agents do not just call APIs — they can

discover services, evaluate costs, transact autonomously, and enable new revenue models for sellers.
