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) clients sign EIP-3009 USDC authorizations that settle as verifiable on-chain transactions, and (2) payments route through FeeRouter contracts that accumulate sub-cent citations into claimable balances, which creators withdraw with a single claim call to avoid per-citation gas costs.

x402 Settlement Schemes on Arc

Payments Protocol Notes / 0.001300 USDC

Explains x402 payment protocol and Arc settlement mechanics for sub-cent 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.
