As the x402 Bazaar reports, from payments Coinbase's facilitator settled. Read 10 Nov 2026, 10:14 UTC. addrbook has not counted these payments itself.

How it asks to be paid

From its own 402 answer at 11 Nov, 00:51 UTC. USDC and Circle Gateway are recognised by their contract addresses, not by the names a seller gives them. How payments are read
