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) with a cite_query, which routes the query to bonded knowledge sources. Each citation triggers an automatic USDC nanopayment via Circle Gateway's batched EIP-3009 authorizations, enabling sub-cent transfers without per-payment gas costs. Arc Testnet provides stablecoin-native settlement with sub-second finality. Every payment generates an on-chain receipt with SHA-256 evidence hash and content integrity proof, readable directly from the Arc RPC with no database required. Agents can operate with spending lines via Shadow Float before their own wallet is funded, with spend policies controlling max price per citation, relevance thresholds, and session caps. The entire transaction is transparent, verifiable on-chain, and visible to creators in real time.

CitePay Autonomous Knowledge Gap Agent — Self-Improving Citation MarketCitePay Markets / score 35 / 0.002000 USDC
Autonomous market orchestration, not citation payment mechanism. Answers 'how does the market improve itself' not 'how do agents pay creators'.CitePay MCP Server — Claude Tool for Paid Citation QueriesCitePay Markets / score 33 / 0.001400 USDC
Explains the agent integration layer: MCP server exposing cite_query tool that any AI agent calls natively to pay creators per citation without custom code. Critical for understanding the mechanism.CitePay On-Chain Audit — Verifiable Citation Receipts on ArcCitePay Markets / score 32 / 0.001000 USDC
