ArcPort
ArcPort is a session-based API payment runtime that lets agents pay for repeated API and model usage on Arc. It offers a charge mode for one-off calls using EIP-3009 signed authorizations through Circle Programmable Wallets and the Gateway deposit flow, and a session mode backed by an on-chain ArcStreamChannel USDC payment-channel contract where an agent opens a bounded budget, authorizes calls with EIP-712 cumulative vouchers, then closes once and is refunded the remainder. It includes a paid Gemini inference endpoint, a copyable arcOSS starter kit with client and session policies, a wagmi/Next reference client, and reproducible on-chain proof artifacts.
