answer context
How do agent payments work with x402 on Arc?
Agent payments with x402 on Arc work through two settlement schemes. In the 'exact' scheme, a resource returns payment requirements, the client signs an EIP-3009 USDC authorization, and the server settles it directly on Arc as a single USDC transfer, making the reader's debit a verifiable on-chain transaction. Alternatively, the Circle Gateway-batched scheme pools many signed authorizations for gasless sub-cent settlement, referenced by a Gateway payment id rather than individual Arc transactions. For multi-contributor works, the FeeRouter contract can route USDC through an on-chain split keyed to creator wallets with basis-point shares. Sub-cent citations accrue to a claimable FeeRouter balance that creators withdraw with a single claim call to avoid per-citation gas costs.
Open answer evidenceDirectly answers the core question: explains x402 settlement on Arc, EIP-3009 USDC authorization flow, exact vs. Circle Gateway schemes, and how agent payments settle. Essential primary reference.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.
