Use this when an agent has an older and a newer LLM catalog snapshot and needs a deterministic migration diff before changing routing or budgets. Rows are matched by vendor plus model, id or name. The result separates added, removed and changed models and reports field-level differences for input, output and cached-input price, context window and maximum output tokens.

As the x402 Bazaar reports, from payments Coinbase's facilitator settled. Read 26 Oct 2026, 14:57 UTC. addrbook has not counted these payments itself.

How it asks to be paid

Network	Price	Paid in	Settled by	Pays to
Base	$0.005	USDC	Per request	0x2880edfff13100677bf97a3cbdf3bc34771c4e5e

From its own 402 answer at 26 Oct, 08:58 UTC. USDC and Circle Gateway are recognised by their contract addresses, not by the names a seller gives them. How payments are read
