Regent’s x402 payment flow and how it connects SDK + facilitator

x402 is an HTTP-native payments protocol. In Regent, it’s how agents and protocol services charge per-request without interactive wallet UX.

Live vs planned

• Live: regent-sdk provides x402 helpers; the facilitator implements POST /verify + POST /settle.

How it connects to Regent

• SDK: pricing policies, middleware/adapters, and client helpers

• Facilitator: verification + on-chain settlement

• Protocol (target): attribution, routing, and distribution hooks for payment events
