## Quick Start

### Installation

```bash
npm install @wia/currency-integration-sdk
```

### Basic Usage

```typescript
import { createClient } from '@wia/currency-integration-sdk';

// Initialize client
const client = createClient({
  apiKey: 'your-api-key',
  environment: 'sandbox' // or 'production'
});

// Get current exchange rate
const rate = await client.getCurrentExchangeRate({
  baseCurrency: 'KRW',
  targetCurrency: 'KPW'
});

console.log(`1 KRW = ${rate.rate} KPW`);

// Convert currency
const conversion = await client.convertCurrency({
  fromCurrency: 'KRW',
  toCurrency: 'KPW',
  amount: 1000000,
  transactionType: 'INDIVIDUAL_TRANSFER',
  priority: 'INSTANT',
  sender: {
    id: 'USER-123456',
    name: 'John Kim',
    country: 'KR',
    accountNumber: '110-123-456789'
  },
  recipient: {
    id: 'USER-789012',
    name: 'Min Park',
    country: 'KP',
    accountNumber: 'NK-456-789012'
  }
});

console.log(`Converted: ${conversion.convertedAmount} KPW`);
console.log(`Status: ${conversion.status}`);
```

### CBDC Example

```typescript
// Create digital wallet
const wallet = await client.createWallet({
  walletType: 'PERSONAL',
  ownerInfo: {
    name: 'John Kim',
    idNumber: '123456-1234567',
    country: 'KR'
  },
  initialBalance: 0
});

// Transfer CBDC
const transaction = await client.transferCBDC({
  fromWalletId: wallet.walletId,
  toWalletId: 'WALLET-KP-789012',
  amount: 50000,
  purpose: 'Payment for goods'
});

console.log(`Transaction: ${transaction.transactionId}`);
console.log(`Status: ${transaction.status}`);
```
