  -H "Authorization: Bearer ${API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{

    "signature": "<SIGNATURE>",
    "data": {
      "makerAsset": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",

      "maker": "<YOUR_WALLET>"
    }
  }'

Safety Rules

1. ALWAYS display swap details before execution
2. WARN if price impact > 1%
3. CHECK token allowance before swap
4. VERIFY slippage settings
5. NEVER execute without user confirmation

Error Handling

Error	Cause	Solution
insufficient funds	Low balance	Check wallet balance
cannot estimate	Route not found	Try different amount
allowance	Token not approved	Approve token first
