x402: an unpaid request gets a 402 with the price and pay-to wallet. addrbook never pays.

As the x402 Bazaar reports, from payments Coinbase's facilitator settled. Read 27 Oct 2026, 12:30 UTC. addrbook has not counted these payments itself.

How it asks to be paid

Network	Price	Paid in	Settled by	Pays to
Solana	$0.05	USDC	Per request	9mMDrHabSf73MPn1ANdANSmsNw2wKiqE7JZ7eD6EUSRc
Base	$0.05	USDC	Per request	0xf6c6e2e530bb311c14a49c1a07c720fc232c07c5

From its own 402 answer at 26 Oct, 15:37 UTC. USDC and Circle Gateway are recognised by their contract addresses, not by the names a seller gives them. How payments are read
