Why do x402 and Gateway make sub-cent source payments possible?

The paying agent treated "Why do x402 and Gateway make sub-cent source payments possible?" as a source-backed answer, not a free scrape. Circle Developer Notes: Circle Gateway batches signed EIP-3009 authorizations so x402 payments can clear at sub-cent values without per-payment gas. Canteen Research: Lepton asks builders to make sub-cent value move for agents and creators: per article, per call, per second, and per citation. Indie Researcher: A source payment should be tiny, automatic, visible to the creator, and tied to the answer that reused the work. It bought the minimum useful bundle of sources, paid each cited creator in USDC atomic units, and wrote a receipt chain that ties the answer to the citations that earned.
