🚀 Deployment Options

1. Hugging Face Spaces (Recommended)

Option A: Docker (Easier)

1. Create a new Space on Hugging Face
2. Select "Docker" as SDK
3. Push this repository to the Space
4. HF will automatically use the Dockerfile

Environment Variables in Space Settings:

PORT=7860
ENABLE_AUTO_DISCOVERY=false
ENABLE_SENTIMENT=true

Option B: Python

1. Create a new Space on Hugging Face
2. Select "Gradio" or "Static" as SDK
3. Create app.py in root:

import os
os.system("python api_server_extended.py")

4. Configure in Space settings:
   • Python version: 3.11
   • Startup command: python api_server_extended.py

---

2. Local Development

# Install dependencies
pip install fastapi uvicorn[standard] pydantic aiohttp httpx requests websockets python-dotenv pyyaml

# Run server (default port 8000)
python api_server_extended.py

# OR specify custom port
PORT=7860 python api_server_extended.py

# Access dashboard
http://localhost:8000  # or your custom port

---

3. Docker Deployment

# Build image
docker build -t crypto-monitor .

# Run container
docker run -p 8000:8000 crypto-monitor

# OR with custom port
docker run -e PORT=7860 -p 7860:7860 crypto-monitor

# Using docker-compose
docker-compose up -d

---

🔧 Configuration

Environment Variables

Create .env file (or set in Hugging Face Space settings):

# Server Configuration
PORT=7860  # Default for HF Spaces
HOST=0.0.0.0

# Features
ENABLE_AUTO_DISCOVERY=false  # Set to false for HF Spaces
ENABLE_SENTIMENT=true

# API Keys (Optional - most providers work without keys)
COINMARKETCAP_API_KEY=your_key_here
CRYPTOCOMPARE_API_KEY=your_key_here
ETHERSCAN_KEY_1=your_key_here
NEWSAPI_KEY=your_key_here

# HuggingFace (Optional)
HUGGINGFACE_TOKEN=your_token_here
SENTIMENT_SOCIAL_MODEL=ElKulako/cryptobert
SENTIMENT_NEWS_MODEL=kk08/CryptoBERT

📋 Verification Checklist

After deployment, verify:

• Dashboard loads at root URL (/)
• No 404 errors in browser console
• No JavaScript errors (check browser console)
• Health endpoint responds: /health
• API endpoints work: /api/providers, /api/pools, /api/status
• WebSocket connects (check connection status in dashboard)
• Provider stats display correctly
• All tabs switchable without errors

---

🐛 Troubleshooting

Dashboard shows 404 errors for CSS/JS

Fixed in latest version! Static files are now inline.

WebSocket connection fails

• Check if HTTPS: WebSocket will use wss:// automatically
• Verify firewall allows WebSocket connections
• Check browser console for error messages

Server won't start

# Check port availability
lsof -i:8000  # or your custom port

# Kill process if needed
pkill -f api_server_extended

# Check logs
tail -f server.log

"Address already in use" error

# Change port
PORT=7860 python api_server_extended.py

🎯 Performance Tips

For Hugging Face Spaces

1. Disable Auto-Discovery: Set ENABLE_AUTO_DISCOVERY=false

2. Limit Dependencies: Comment out heavy packages in requirements.txt if not needed:

   • torch (~2GB)
   • transformers (~1.5GB)
   • duckduckgo-search

3. Use Smaller Docker Image: Dockerfile already uses python:3.11-slim

For Production

1. Enable Redis Caching:

   docker-compose --profile observability up -d
   

2. Add Rate Limiting: Configure nginx/Cloudflare in front

3. Monitor Resources: Use Prometheus/Grafana (included in docker-compose)

📊 Resource Requirements

Minimum

• RAM: 512MB
• CPU: 1 core
• Disk: 2GB

Recommended

• RAM: 2GB
• CPU: 2 cores
• Disk: 5GB

With ML Models (torch + transformers)

• RAM: 4GB
• CPU: 2 cores
• Disk: 10GB

🔗 Useful Endpoints

Endpoint	Description
/	Main dashboard
/health	Health check (JSON)
/api/status	System status
/api/stats	Complete statistics
/api/providers	List all providers
/api/pools	List all pools
/docs	API documentation (Swagger)
/test_websocket.html	WebSocket test page
