Use when an agent is written against the Anthropic Messages API and must call a model with no account: the same request and response shape - system as its own field, content as text blocks, stop_reason - so pointing your client at this URL is all it takes. One flat price per call, whatever the size. Automatic failover across several large models. Do not use for the OpenAI shape (/v1/chat/completions serves that one). You are only charged if the answer is delivered.

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 7 Nov 2026, 20:31 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	0xc210ea7d5692a6401adf25bbcb7acde9cdb7e9ff
Polygon	$0.005	USDC	Per request	0xc210ea7d5692a6401adf25bbcb7acde9cdb7e9ff
Arbitrum	$0.005	USDC	Per request	0xc210ea7d5692a6401adf25bbcb7acde9cdb7e9ff

From its own 402 answer at 7 Nov, 04:29 UTC. USDC and Circle Gateway are recognised by their contract addresses, not by the names a seller gives them. How payments are read
