Anthropic Messages API over x402 - point the Anthropic SDK (or Claude Code / the Agent SDK) at base_url https://agent402.tools/v1/pro and pay $0.10 per call in USDC, no API key, no signup. Same models, caps and price as this tier's /chat/completions route; any model here is served through the Messages wire (Claude natively, others translated). Depth: `effort` (low..max) on Claude 4.7+ and Haiku 5.5, thinking.budget_tokens on older Claude.

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

independent of the seller: 1

USDC payments: 1

Counted by addrbook from USDC transfers to the wallets it asks to be paid at, on Arc. A payer is independent when it is not one of the seller's own wallets and the seller did not fund it; the largest payer made 100% of the payments. Naming a wallet does not prove it is this seller's, unless a signature shows that above. Counted 10 Nov 2026, 18:15 UTC. How payers are counted

As the x402 Bazaar reports, from payments Coinbase's facilitator settled. Read 10 Nov 2026, 10:15 UTC. addrbook has not counted these payments itself.
