## 🔑 CRITICAL REMINDERS

### ⚠️ THIS IS AN UPDATE
```
YOU ARE NOT CREATING A NEW SPACE!
YOU ARE UPDATING AN EXISTING SPACE!

This means:
✅ Use existing space repository
✅ Keep existing functionality (if any)
✅ ADD new endpoints
✅ ENHANCE existing features
✅ Don't break existing integrations
```

### ⚠️ PRIORITY ORDER
```
1. MUST HAVE (implement first):
   - GET /api/market
   - GET /api/ohlcv
   - GET /api/news/latest
   - GET /api/sentiment/global
   - GET /api/ai/signals

2. SHOULD HAVE (implement second):
   - All other REST endpoints
   - WebSocket /ws/ticker

3. NICE TO HAVE (implement if time):
   - Advanced AI features
   - WebSocket /ws/trades
   - Blockchain endpoints
```

### ⚠️ QUALITY STANDARDS
```
✅ ALL endpoints must return valid JSON
✅ ALL errors must follow the standard format
✅ ALL endpoints must have caching
✅ ALL responses must include timestamp
✅ ALL endpoints must handle timeouts gracefully
✅ ALL data sources must have fallbacks
```

### ⚠️ PERFORMANCE REQUIREMENTS
```
Response Times:
- Price endpoints: < 100ms
- Market data: < 500ms
- News/Sentiment: < 1s
- AI predictions: < 2s

Caching TTL:
- Prices: 5 seconds
- OHLCV: 60 seconds
- News: 5 minutes
- AI signals: 2 minutes

Rate Limits:
- Per IP: 100 requests/minute
- Per endpoint: Varies (see specs)
```

## 🚨 COMMON MISTAKES TO AVOID

### ❌ DON'T:
```
❌ Create a new HuggingFace Space (it already exists!)
❌ Remove existing functionality
❌ Hard-code API keys in the code
❌ Skip error handling
❌ Ignore caching requirements
❌ Skip testing
❌ Deploy without local testing
❌ Use synchronous code (use async/await)
❌ Return inconsistent response formats
❌ Ignore rate limiting
```

### ✅ DO:
```
✅ Update the existing Space
✅ Use environment variables for secrets
✅ Implement proper error handling
✅ Add caching to every endpoint
✅ Test locally before deploying
✅ Use async/await throughout
✅ Follow the standard response format
✅ Implement rate limiting
✅ Add fallback mechanisms
✅ Log all errors
```
