answer context
How should AI agents pay creators per citation on Arc?
Based on the purchased sources, AI agents should pay creators per citation on Arc using a two-layer approach: (1) use x402 settlement schemes to handle payment authorization and on-chain settlement, where the client signs an EIP-3009 USDC authorization and the server settles it as a single USDC transfer on Arc; and (2) route those payments through FeeRouter to accumulate sub-cent citations into claimable balances that creators withdraw in a single transaction, avoiding per-citation gas costs. FeeRouter also enables multi-contributor works to divide payments automatically through on-chain splits keyed to creator wallets.

Explains x402 HTTP 402 payment protocol and Arc settlement mechanics—essential for understanding how to execute per-citation payments on Arc.Seed/demo content from Payments Protocol Notes. Title: x402 Settlement Schemes on Arc. Excerpt: x402 turns HTTP 402 into a real payment step: a resource returns payment requirements, the client signs an EIP-3009 USDC authorization, and the server settles it. The 'exact' scheme settles that authorization directly on Arc as a single USDC transfer, so the reader's debit is a verifiable on-chain transaction. The Circle Gateway-batched scheme instead pools many signed authorizations for gasless sub-cent settlement, referenced by a Gateway payment id rather than one Arc tx.
