# Test CORS headers from different origins
curl -H "Origin: http://localhost:8010" -H "Access-Control-Request-Method: GET" \
     -X OPTIONS http://localhost:8000/health

# Should return proper Access-Control-Allow-Origin headers

✅ Systemd Service Status

# Check service status
systemctl status aitbc-coordinator-api
systemctl status aitbc-exchange-api
systemctl status aitbc-blockchain-rpc
systemctl status aitbc-multimodal-gpu

# Check service logs
journalctl -u aitbc-coordinator-api -n 20
journalctl -u aitbc-exchange-api -n 20

✅ Development Script Testing

# Test GPU exchange status
cd /home/oib/windsurf/aitbc
python3 dev/gpu/gpu_exchange_status.py

# Should show updated port information
