## Using Labels in Risk Assessment

Labels provide context for risk evaluation:

```javascript theme={null}
function assessRisk(address, labels) {
  // Known exchanges are generally lower risk
  if (labels.type === 'cex' && labels.subtype === 'hot_wallet') {
    return 'low';
  }

  // Toxic flotsam is high risk
  if (labels.type === 'flotsam' && labels.subtype === 'toxic') {
    return 'high';
  }

  return 'medium';
}
```

## Response Example

```json theme={null}
{
  "address": "0x...",
  "labels": {
    "type": "cex",
    "subtype": "hot_wallet",
    "name": "Binance",
    "confidence": 0.99
  }
}
```
