ArcTrust is a usage-based API monetization and discovery layer for the agent economy. Instead of subscriptions, ArcTrust lets services monetize per call and offer discounted bulk credits. In our current demo, we use Circle Wallets with USDC transfers to simulate per-call settlement and bulk purchase flows. Bulk prepaid demand becomes a lightweight reputation signal—if users are willing to buy 10 or 100 calls up front, the provider is delivering repeat value. Our MVP: providers set pay-per-call pricing and bulk bundles; users spend from Circle Wallet balances via transfers; bulk purchases update the demand score. ArcTrust provides flexible access for new users and better economics for high-frequency users. We focused on building something demo-ready on event timelines. If we had more time, we’d also integrate more advanced settlement primitives to scale beyond transfers, but Circle Wallets gave us a solid foundation for wallets, balances, and spend control.
