## 💡 Examples

### Example 1: Complete Customer Onboarding

```typescript
import KYCAMLClient from '@wia-standards/kyc-aml-sdk';

const client = new KYCAMLClient({ /* config */ });

async function onboardCustomer(customerData) {
  // Step 1: Create customer record
  const customer = await client.createCustomer({
    customerType: 'individual',
    personalInfo: customerData.personalInfo,
    contactInfo: customerData.contactInfo
  });

  // Step 2: Upload identity documents
  const docUpload = await client.uploadDocument(
    customer.data.customerId,
    'passport',
    customerData.passportFile
  );

  // Step 3: Verify document
  const verification = await client.verifyDocument(
    docUpload.data.documentId
  );

  // Step 4: Perform screenings
  const [sanctions, pep] = await Promise.all([
    client.sanctionsScreening({
      searchType: 'individual',
      firstName: customerData.personalInfo.legalName.firstName,
      lastName: customerData.personalInfo.legalName.lastName,
      dateOfBirth: customerData.personalInfo.dateOfBirth
    }),
    client.pepScreening({
      fullName: customerData.personalInfo.legalName.fullName,
      country: customerData.personalInfo.nationality[0]
    })
  ]);

  // Step 5: Assess risk
  const risk = await client.calculateRiskScore(
    customer.data.customerId,
    {
      customerType: 'individual',
      geographicRisk: 'low',
      productRisk: 'medium',
      isPEP: pep.data.pepStatus === 'pep'
    }
  );

  // Step 6: Initiate CDD
  const cdd = await client.initiateCDD(
    customer.data.customerId,
    risk.data.overallRiskRating === 'high' ? 'enhanced' : 'standard',
    'new_customer'
  );

  return {
    customerId: customer.data.customerId,
    cddId: cdd.data.cddId,
    riskRating: risk.data.overallRiskRating,
    sanctionsClear: sanctions.data.clearanceStatus === 'clear',
    pepStatus: pep.data.pepStatus
  };
}
```

### Example 2: Transaction Monitoring

```typescript
async function monitorTransaction(transactionData) {
  // Submit transaction for monitoring
  const transaction = await client.submitTransaction({
    transactionType: 'wire',
    amount: transactionData.amount,
    originator: transactionData.originator,
    beneficiary: transactionData.beneficiary,
    transactionDetails: transactionData.details
  });

  // Check for alerts
  const alerts = await client.getTransactionAlerts(
    transaction.data.transactionId
  );

  // Handle alerts
  if (alerts.data.alerts.length > 0) {
    console.log(`⚠️ ${alerts.data.alerts.length} alert(s) generated`);
    
    for (const alert of alerts.data.alerts) {
      if (alert.alertStatus === 'open') {
        // Escalate high-severity alerts
        if (alert.alertType === 'structuring' || 
            alert.alertType === 'sanctions_hit') {
          await escalateAlert(alert);
        }
      }
    }
  }

  return {
    transactionId: transaction.data.transactionId,
    clearanceStatus: transaction.data.clearanceStatus,
    alertCount: alerts.data.alerts.length
  };
}
```

### Example 3: Generate SAR

```typescript
async function generateSAR(customerId, suspiciousActivity) {
  // Create SAR
  const sar = await client.createSAR({
    reportType: 'initial',
    subject: {
      subjectType: 'individual',
      subjects: [{
        subjectId: customerId,
        role: 'primary',
        customerRef: customerId,
        relationshipToInstitution: 'customer',
        accountsInvolved: [suspiciousActivity.accountNumber]
      }]
    },
    suspiciousActivity: {
      activityType: ['structuring'],
      activityStartDate: suspiciousActivity.startDate,
      activityEndDate: suspiciousActivity.endDate,
      totalAmount: {
        value: suspiciousActivity.totalAmount,
        currency: 'USD'
      },
      narrative: suspiciousActivity.narrative,
      redFlags: suspiciousActivity.redFlags
    },
    internalTracking: {
      caseNumber: generateCaseNumber(),
      assignedTo: getCurrentUser(),
      investigationStartDate: new Date()
    }
  });

  // Get approval
  const approved = await requestSARApproval(sar.data.sarId);

  if (approved) {
    // Submit to FinCEN
    const submission = await client.submitSAR(sar.data.sarId);
    
    console.log(`✅ SAR filed: ${submission.data.filingId}`);
    return submission.data;
  }
}
```
