What does an agent need to settle nanopayments to creators on Arc, and how does budgeting work?
To settle nanopayments to creators on Arc, an agent needs: (1) USDC stablecoin for gas and settlement, (2) x402 payment protocol support for sub-cent value transfers, (3) batching infrastructure (like Circle Gateway's EIP-3009 authorizations) to avoid per-payment gas costs, and (4) Arc's app kits for payment workflows with sub-second finality. For budgeting, agents use covenant-style spend controls (like Forum mandates) that bind the agent budget, publish receipts, and make spend enforcement enforceable rather than advisory. Payment amounts should be tiny, automatic, visible to creators, and tied to the specific answer or citation that reused their work.
