## Subject: Space Update Request - Comprehensive API Implementation

Dear Hugging Face Team,

This is a **SPACE UPDATE REQUEST** for implementing a comprehensive cryptocurrency data API that will serve as the unified backend for the Dreammaker Crypto Trading Platform.

---

## 🎯 Request Summary

**Type:** Update Existing Space  
**Goal:** Implement 30+ API endpoints to serve all data needs  
**Priority:** HIGH  
**Timeline:** As soon as possible  

---

## 📋 What We Need

We need our HuggingFace Space to provide a complete REST API and WebSocket service with the following capabilities:

### Core Endpoints (Must Have)
1. Market data (list of cryptocurrencies with prices)
2. OHLCV chart data (candlestick data for charts)
3. Real-time price ticker
4. Latest cryptocurrency news
5. Market sentiment analysis (Fear & Greed Index)
6. AI trading signals
7. Price predictions
8. WebSocket for real-time updates

### Additional Endpoints (Should Have)
- Order book data
- Recent trades
- Blockchain transaction history
- Whale alerts (large transfers)
- Market statistics
- Historical data

- Smart caching (5s - 10min TTL depending on data type)
- Support for 1000+ concurrent WebSocket connections
- Rate limiting per IP/API key

### 4. Features
- Automatic fallback between data sources
- Consistent error handling
- CORS enabled for all origins

## 🚀 Example Endpoints

Here are a few examples of what we need:

**GET /api/market?limit=100**
```json
{
  "success": true,
  "items": [
    {
      "symbol": "BTC",
      "name": "Bitcoin",
      "price": 42150.25,
      "change_24h": 2.34,
      "volume_24h": 28500000000,
      "market_cap": 825000000000
    }
  ]
}
```

**GET /api/ohlcv?symbol=BTC/USDT&timeframe=1h&limit=100**
```json
{
  "success": true,
  "data": [
    {
      "t": 1733428800000,
      "o": 42100.50,
      "h": 42250.75,
      "l": 42050.25,
      "c": 42150.25,
      "v": 125.45
    }
  ]
}
```

**GET /api/ai/signals**
```json
{
  "success": true,
  "signals": [
    {
      "symbol": "BTC/USDT",
      "type": "buy",
      "confidence": 0.85,
      "entry_price": 42150.25,
      "target_price": 43500.00,
      "stop_loss": 41000.00
    }
  ]
}
```

## 📞 Questions & Support

If you have any questions about:
- API specifications
- Technical implementation
- Data sources
- Performance requirements
- Testing procedures

Please refer to the complete documentation in `HUGGINGFACE_SPACE_DEPLOYMENT_REQUEST.md` or contact us.

## 🎯 Why This Matters

This update will:
- Centralize all data access through one endpoint
- Reduce complexity in our frontend (60+ files currently making API calls)
- Improve performance with smart caching
- Provide better reliability with fallback mechanisms
- Enable real-time features via WebSocket
- Add AI-powered trading signals

**Current situation:** Data scattered across multiple APIs, hard to maintain  
**After update:** Single, unified, powerful API serving all needs
