Merchant Billing Adapter Demo · Non-custodial · Testnet
⚠️ This is a demo. It runs entirely on testnet with a DEMO merchant address — no real wallets, keys or funds are involved. It shows how an API provider accepts x402 stablecoin micropayments; it does not move real money.

Accept agentic stablecoin payments on your API

The sell-side of agentic commerce. Register a paid endpoint, generate the x402 402 Payment Required challenge, meter every paid call, and reconcile settlement — all as drop-in middleware. Built for the x402 standard (Coinbase + Cloudflare Foundation), live on 6 production surfaces with Visa and Stripe pushing agentic payments.
