+- **Health Monitoring**: Real-time API status tracking
+
+### 2. **API Status Dashboard (`/admin`)**
+- **Real-time Monitoring**: Live API health status
+- **Visual Interface**: Clean, professional dashboard
+- **Manual Control**: Reset API states manually
+- **Health Metrics**: Overall system health scoring
+- **Auto-refresh**: 30-second automatic updates
+
+### 3. **Enhanced API Routes**
+- **`/api/status`**: GET/POST endpoint for API management
+- **`/api/gemini-vision`**: Updated with multi-API support
+- **Perplexity Integration**: Research insights for uploaded documents
+
+### 4. **Production-Ready Features**
+- **TypeScript Safety**: Full type checking and error handling
+- **Build System**: Successful production builds
+- **Environment Variables**: Secure API key management

+GEMINI_API_KEY_2=your_second_gemini_api_key_here
+GEMINI_API_KEY_3=your_third_gemini_api_key_here
+
+# Perplexity API for insights and research
+PERPLEXITY_API_KEY=your_perplexity_api_key_here
+```
+
+## 🎯 How It Works
+
+### Automatic Failover Logic:
+1. **Primary**: Starts with first Gemini API key
+2. **Rotation**: Cycles through available keys when limits hit
+3. **Recovery**: Automatically reactivates APIs after cooldown
+4. **Monitoring**: Tracks errors and success rates
+5. **Fallback**: Graceful degradation to mock responses
+
+### API Manager Features:
+- **Round-robin load balancing** across multiple Gemini APIs
+- **Error tracking** with automatic recovery after 5 minutes  
+- **Rate limit detection** and automatic API rotation
+- **Timeout handling** with configurable retry logic
