answer context
How should AI agents pay creators per citation on Arc?
Based on the available sources, AI agents should pay creators per citation on Arc using one of two approaches: (1) the 'exact' x402 settlement scheme, which settles payment authorizations directly on Arc as a single USDC transfer per citation, making each reader's debit a verifiable on-chain transaction; or (2) the FeeRouter contract approach, which routes USDC through an on-chain split to the creator's wallet, with sub-cent citations accruing to a claimable balance that the creator withdraws with a single claim call to avoid excessive per-citation gas costs.
Open answer evidenceExplains x402 payment protocol and Arc settlement mechanics for citations. Essential technical grounding.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.
