  3. your x402 client checks amount ≤ $0.003 and signs a USDC transfer authorization to payTo with your wallet
  4. retry the same POST with PAYMENT-SIGNATURE: <base64> (x402 v2) or X-PAYMENT (v1 clients)
  5. ← 200 OK with the result JSON + PAYMENT-RESPONSE header (base64 settlement receipt, tx hash on Base)
