ArcPay Commerce Suite

ArcPay Commerce Suite is a production-style set of four Arc-native payment products built around Circle Gateway, x402, Nanopayments, and USDC on Arc Testnet. Instead of subscriptions, invoices, prepaid credits, ad-driven monetization, or custodial balances, each product charges exactly when value is delivered. The suite includes four live flows mapped to the hackathon tracks. AgentMeter API Engine monetizes API calls one request at a time. AgentMesh Payment Loop lets a buyer agent pay seller agents for data, scoring, and verification without batching or platform custody. Compute Drip Billing charges for compute row by row so payment tracks actual work completed. ClickCart Nano Commerce charges for previews, unlocks, creator tips, and stream ticks as individual economic events. Each site now supports a real browser-based checkout path for humans. A user opens the site, connects an injected EVM wallet, switches to Arc Testnet, deposits USDC into Circle Gateway, then clicks a priced action and completes a real x402 payment flow. For agents, every project also exposes paid endpoints that can be called programmatically with GatewayClient and a funded Arc wallet. To make the browser flow reliable, the frontend uses a same-origin Vercel proxy that forwards requests to the live Render API and mirrors the x402 payment headers. That lets the browser read and act on PAYMENT-REQUIRED and PAYMENT-RESPONSE without breaking on cross-origin restrictions. The paid routes themselves still settle against Arc Testnet using Circle’s batching model and USDC.
