answer context

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 enables this workflow: agents call the CitePay MCP Server (a Claude-native tool) 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 payment generates an on-chain receipt with SHA-256 evidence hash and content integrity proof, visible directly on Arc's RPC. Agents can operate under spend policies (max price per citation, relevance thresholds, session caps) enforced via mandates. The CitePay On-Chain Audit page provides real-time verification of all USDC flows to creators—no database, pure chain verification.
