│   (Controllers, Routes, Webhooks)        │
├─────────────────────────────────────────┤
│           Service Layer                  │

├─────────────────────────────────────────┤
│          Clay Layer        │

├─────────────────────────────────────────┤
│         Infrastructure Layer             │

## Key Components

### Step 1: Client Wrapper
```typescript
// src/clay/client.ts
export class ClayService {
  private client: ClayClien
