How do AI agents pay creators per citation using USDC on Arc Testnet?
AI agents pay creators per citation using USDC on Arc Testnet through Circle Gateway's x402 protocol. The CitePay Markets platform implements this workflow: agents call the CitePay MCP Server (a Claude-native tool interface) with cite_query requests. Each citation triggers a nanopayment in USDC via Circle Gateway's batched EIP-3009 authorizations, which clear sub-cent values without per-payment gas costs. Payments settle on Arc Testnet with sub-second finality. Every PAY decision generates an on-chain receipt with SHA-256 evidence hash and content integrity proof, visible to creators. Agents can operate under spend policies (max price per citation, relevance thresholds, session caps) enforced via Arc's app kits. For agents without pre-funded wallets, Shadow Float provides behavior-backed USDC spending lines so they can buy x402 services before their own wallet is funded, with repayment and overreach blocking tracked on-chain.
