I don't think people really understand how important sub-cent gas free payments will be for the internet. @arc + @circle + @USDC provides this today.
Quicknode is the prime example of a data provider that will help unlock machine to machine payment use cases that fiat rails can't support.
Some agents live for one trade. Some never stop polling a balance.
On @arc both pay $0.0001 USDC per RPC call through Nanopayments powered by @circle Gateway. No account, no API key.
Pay on Arc, read any chain.
