How it asks to be paid

Network	Price	Paid in	Settled by	Pays to
Base	$0.05	USDC	Per request	0xbf4164e07552e4c1b1b1597e72c7acaa3f0a1c58

From its own 402 answer at 27 Oct, 11:42 UTC. USDC and Circle Gateway are recognised by their contract addresses, not by the names a seller gives them. How payments are read
