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 settlement schemes that handle sub-cent transactions efficiently. The 'exact' scheme settles payment directly on Arc as a single USDC transfer via EIP-3009 authorization, making the reader's debit a verifiable on-chain transaction. Alternatively, the Circle Gateway-batched scheme pools multiple signed authorizations for gasless sub-cent settlement. To manage the volume of sub-cent citations, creators should use FeeRouter, which routes USDC through an on-chain split contract keyed to the creator's wallet, accumulates sub-cent citations to a claimable balance, and allows the creator to withdraw with a single claim call—keeping per-citation gas costs manageable.
