## Examples

### Cost-Optimized Transcription Service
```typescript
// services/cost-optimized-transcription.ts
import { createClient } from '@deepgram/sdk';

interface CostConfig {
  maxMonthlySpend: number;
  warningThreshold: number; // percentage
  model: string;
  enabledFeatures: {
    diarization: boolean;
    smartFormat: boolean;
  };
}

interface CostMetrics {
  currentMonthMinutes: number;
  currentMonthCost: number;
  projectedMonthlyCost: number;
}

export class CostOptimizedTranscription {
  private client;
  private config: CostConfig;
  private metrics: CostMetrics;
  private modelCosts: Record<string, number> = {
    'nova-2': 0.0043,
    'nova': 0.0043,
    'base': 0.0048,
    'enhanced': 0.0145,
  };

  constructor(apiKey: string, config: Partial<CostConfig> = {}) {
    this.client = createClient(apiKey);
    this.config = {
      maxMonthlySpend: config.maxMonthlySpend ?? 100,
      warningThreshold: config.warningThreshold ?? 80,
      model: config.model ?? 'nova-2',
      enabledFeatures: config.enabledFeatures ?? {
        diarization: false,
        smartFormat: true,
      },
