📊 Data Flow

1. User enters search query (e.g., "bitcoin")
2. Frontend sends via WebSocket to backend
3. Backend receives query and starts research
4. ResearchAgent analyzes query type (crypto/news/general)
5. Selects appropriate scraper:
   • "bitcoin" → CryptoScraper (CoinGecko)
   • "news" → NewsScraper (NewsAPI)
   • "general" → GeneralScraper (Wikipedia)
6. Scraper fetches real data from API
7. Backend sends progress updates via WebSocket:
   • 🚀 STARTED
   • ⏳ PROGRESS (searching...)
   • ✅ COMPLETED (with results)
8. Frontend displays results in real-time
9. Results stored in history with ID
10. User can export or delete results

---

🔐 Security & Best Practices

• ✅ API keys stored in .env file (not committed)
• ✅ CORS properly configured
• ✅ Input validation on all endpoints
• ✅ Error handling with meaningful messages
• ✅ Logging at critical points
• ✅ Async/await for non-blocking operations
• ✅ Timeout handling for external API calls
• ✅ Retry logic for failed requests

---

🧪 Testing

Test All APIs

python test_openai_key.py

Test Scrapers

python test_scrapers.py

Manual Testing

1. Navigate to http://localhost:3000
2. Try different searches:
   • "bitcoin price" (CoinGecko)
   • "machine learning" (NewsAPI)
   • "python" (Wikipedia)
3. Test export/delete functionality
4. Check browser console (F12) for errors

---

📈 Performance

Metric	Value
Startup Time	< 2 seconds
Search Time	2-5 seconds
Response Time	< 1 second
API Call Timeout	10 seconds
Max Retries	3 attempts
Real-time Updates	< 500ms

🐛 Troubleshooting

Issue: "NEWS_API_KEY not configured"

Solution:

1. Create .env file in project root
2. Add: NEWS_API_KEY=your_key
3. Get key from https://newsapi.org
4. Restart backend

Issue: "Connection error"

Solution:

1. Check internet connection
2. Verify API endpoints are accessible
3. Check firewall settings

Issue: "WebSocket connection failed"

Solution:

1. Verify backend is running on port 8000
2. Check CORS settings in backend
3. Restart both frontend and backend

Issue: "Results not showing"

Solution:

1. Open browser DevTools (F12)
2. Check Network tab for failed requests
3. Check Console for errors
4. Verify API keys are correct
