Payments Protocol Notes
This receipt binds a source payment to the answer that used it; FeeRouter-routed receipts accrue into creator-claimable balances. The previous hash links it into the append-only attribution ledger.

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) x402 settlement schemes to handle payment authorization and on-chain settlement, and (2) FeeRouter split payouts to route USDC to creators while accumulating sub-cent citations into claimable balances. The x402 'exact' scheme settles authorizations directly on Arc as single USDC transfers, while the Circle Gateway-batched scheme pools authorizations for gasless sub-cent settlement. FeeRouter then divides payments automatically via on-chain splits keyed to creator wallets with basis-point shares, and accrues sub-cent citations to a claimable balance that creators withdraw with a single claim call, avoiding per-citation gas costs.
Open answer evidenceExplains x402 HTTP 402 payment protocol and Arc settlement mechanics for citations. Essential technical foundation.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.
