1. POST https://grokzilla.shop/api/skills/agent-ready-audit with the JSON body, no payment header
2. ← 402 Payment Required + PAYMENT-REQUIRED header: base64 JSON {x402Version: 2, accepts: [{scheme: "exact", network: "eip155:8453", asset: USDC, amount: "199300", payTo}]} (same JSON in the body)
3. your x402 client checks amount ≤ $0.1993 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)
