## 🔑 Configuration Required

### Environment Variables

Your `.env` file currently has:
```env
STEAM_API_KEY=14C1687449C5C4CB79953094DB8E6CC0
STEAM_APIS_KEY=DONTABUSEORPEPZWILLNAGASAKI
```

✅ **Already configured!** The code now checks for both:
- `STEAM_APIS_KEY` (primary - your SteamAPIs.com key)
- `STEAM_API_KEY` (fallback)

---

## 🧪 Testing Status

### Backend Health Check
```
✅ Server running: http://localhost:3000
✅ Health check: OK
✅ Market endpoint: Working (23 items)
✅ API Key: Configured
```

### Ready to Test

**YOU NEED TO:**
1. **Restart Backend** (to load STEAM_APIS_KEY changes)
   ```bash
   # Press Ctrl+C to stop current server
   npm run dev
   ```

2. **Test Market Page**
   - Go to: http://localhost:5173/market
   - Should load items immediately
   - No more infinite loading

3. **Login via Steam**

## ⚠️ Known Limitations

### 1. Pricing System
**Status:** Placeholder algorithm  
**Impact:** Prices are estimated, not real market prices  
**Solution Needed:** Integrate real pricing API:
- Steam Market API
- CSGOBackpack
- CSFloat
- SteamAPIs.com pricing endpoints

### 2. Steam Trade Offers
**Status:** Not implemented  
**Impact:** No actual trade offers sent  
**Solution Needed:** 
- Set up Steam bot accounts
- Integrate steam-tradeoffer-manager
- Handle trade confirmations
- Implement trade status tracking

### 3. Inventory Caching
**Status:** No caching  
**Impact:** Fetches inventory every page load  
**Solution Needed:**
- Implement Redis caching
- Cache for 5-10 minutes
- Reduce API calls

## 🐛 Troubleshooting Guide

### Market Page Still Loading
```bash
# Verify items in database
curl http://localhost:3000/api/market/items

# If no items, seed database
node seed.js

# Restart frontend
cd frontend && npm run dev
```

### Sell Page Shows API Error
```bash
# Check environment variable
grep STEAM_APIS_KEY .env

# Check backend logs for errors
# Look for: "❌ STEAM_API_KEY or STEAM_APIS_KEY not configured"

# Restart backend
npm run dev
```

### Inventory Not Loading
- Make Steam inventory PUBLIC
- Check backend logs for Steam API errors
- Verify API key is valid on steamapis.com
- Check rate limits (free tier: 100k/month)
