Flare Builder Online Workshops - Session 18: x402 Unleashed: Payments and Autonomous Agents on Flare

​Flare Builder Online Workshops - Session 18: x402 Unleashed: Payments and Autonomous Agents on Flare

Dive into the mechanics of x402, the protocol that brings HTTP‑native payments to the web by reviving the long‑reserved HTTP 402 "Payment Required" status code. In this workshop, you'll build and run a complete x402 payment flow on Flare, leveraging EIP‑3009 for gasless, front‑running‑resistant token transfers. You'll deploy smart contracts, run a payment‑aware backend, and interact with it using an automated agent, gaining a clear, end‑to‑end understanding of how x402 enables servers to request payment directly through HTTP, and how clients can settle those payments with off‑chain signatures and verification on the Flare blockchain.
