api.
x402 endpoint tester API (payment-required validator). x402 endpoint doctor for sellers: probes your paid URL unpaid (GET, HEAD, empty POST, CORS preflight; never pays) and returns a grade and a fix list. Checks the v2 PAYMENT-REQUIRED header and v1 body, every accepts entry (USDC asset, EIP-712 domain, Solana feePayer, atomic amount, payTo), multichain price consistency and the Bazaar declaration against its own JSON Schema.

As the x402 Bazaar reports, from payments Coinbase's facilitator settled. Read . 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 | 0x3c1a1e01e790cd326495631b3b38bd7068f08d6f |
From its own 402 answer at UTC. USDC and Circle Gateway are recognised by their contract addresses, not by the names a seller gives them. How payments are read
