# ✅ Pricing System & Phase Detection - COMPLETE

## 🎉 What's Been Implemented

### 1. Phase Detection ✅
- Automatically detects Doppler phases from item names/descriptions
- Supported phases: Ruby, Sapphire, Black Pearl, Emerald, Phase 1-4
- Phase multipliers applied to prices (Ruby 3.5x, Sapphire 3.8x, etc.)
- Integrated into inventory loading

### 2. Real Market Prices Only ✅
- **Removed all hardcoded prices**
- Only uses real prices from SteamAPIs.com
- Items without market data show as "no price available"
- No fake/estimated prices anymore

### 3. Database Storage ✅
- Added `marketPrice` field to Item model
- Added `priceUpdatedAt` timestamp
- Added `phase` field for Doppler items
- Proper indexes for performance

### 4. Automatic Updates ✅
- Scheduled hourly price updates (configurable)
- Fetches from SteamAPIs.com `/market/items/{AppID}`
- Updates CS2 and Rust items automatically
- Logs update results

### 5. Admin Panel ✅
- Complete admin interface at `/admin`
- Price update controls
- System statistics
- Items without prices list
- Real-time status monitoring

## 🚀 Quick Start

### Step 1: Make Yourself Admin

Run this script to grant admin access:

```bash
node make-admin.js
```

This will:
- Find your user (Steam ID: 76561198027608071)
- Set staffLevel to 3 (admin)
- Grant access to admin routes

### Step 2: Restart Backend

```bash
# Stop current server (Ctrl+C)
npm run dev
```

The server will:
- Load pricing service
- Start automatic hourly updates (if enabled)
- Register admin routes

### Step 3: Initial Price Update

**Option A: Via Admin Panel (Recommended)**
1. Go to http://localhost:5173/admin
2. Select "All Games"
3. Click "Update Prices Now"
4. Wait for completion (~30 seconds)

**Option B: Via API**
```bash
curl -X POST http://localhost:3000/api/admin/prices/update \
  -H "Content-Type: application/json" \
  -H "Cookie: accessToken=YOUR_TOKEN" \
  -d '{"game": "all"}'
```

### Step 4: Test Sell Page

1. Go to http://localhost:5173/sell
2. Load your Steam inventory
3. Items now show real market prices
4. Items without prices won't appear (no fake prices!)

## 🔧 Configuration

### Environment Variables

```env
# Steam API Key (REQUIRED)
STEAM_APIS_KEY=your_steamapis_key_here

# Admin Access (Your Steam ID already added to script)
# Or add to .env for multiple admins:
ADMIN_STEAM_IDS=76561198027608071,76561198000000000

# Enable automatic price updates in development (OPTIONAL)
ENABLE_PRICE_UPDATES=true
```

### Automatic Updates

**Default:** Runs every 1 hour in production

**Disable in Development:**
```env
# Don't set ENABLE_PRICE_UPDATES or set to false
```

**Change Interval:**
```javascript
// In index.js
pricingService.scheduleUpdates(120 * 60 * 1000); // 2 hours
```

---

## 📡 API Endpoints

All admin endpoints require:
- Authentication (logged in via Steam)
- Admin access (staffLevel >= 3)

### Update Prices
```
POST /api/admin/prices/update
Body: { "game": "cs2" | "rust" | "all" }
```

### Get Price Status
```
GET /api/admin/prices/status
```

### Get Items Without Prices
```
GET /api/admin/prices/missing?game=cs2&limit=50
```

### Estimate Price for Item
```
POST /api/admin/prices/estimate
Body: { "itemId": "item_id_here" }
```

### Get System Stats
```
GET /api/admin/stats
```

### Schedule Updates
```
POST /api/admin/prices/schedule
Body: { "intervalMinutes": 60 }
```

## 🎯 How It Works

### Phase Detection Flow

1. **Inventory Load** → User goes to Sell page
2. **Fetch Steam Data** → Get item descriptions
3. **Parse Phase** → Scan name + description for keywords
4. **Apply Multipliers** → Adjust price based on phase

**Example:**
```
Item: "★ Karambit | Doppler (Factory New) - Ruby"
Phase Detected: "Ruby"
Base Price: $400
With Ruby Multiplier (3.5x): $1,400
```

### Price Update Flow

1. **Trigger** → Scheduled (hourly) or manual (admin panel)
2. **Fetch API** → GET SteamAPIs.com/market/items/730
3. **Parse Response** → Extract item names and 30-day avg prices
4. **Query DB** → Get all active items for game
5. **Match & Update** → Compare by name, update marketPrice
6. **Log Results** → Report updated/not found/errors

**Example Log:**
```
📊 Fetching CS2 market prices...
✅ Fetched 5000 prices for CS2
🔄 Updating database prices for CS2...
✅ Price update complete for CS2:
   - Total items: 150
   - Updated: 142
   - Not found: 8
   - Errors: 0
```

### Price Calculation (Sell Page)

```javascript
1. Fetch market price from database
   ↓
2. If no price → Item not shown (no fake prices!)
   ↓
3. Apply wear multiplier (FN=1.0, MW=0.85, etc.)
   ↓
4. Apply phase multiplier (Ruby=3.5x, etc.)
   ↓
5. Apply StatTrak multiplier (1.5x)
   ↓
6. Apply Souvenir multiplier (1.3x)
   ↓
7. Show final price to user
```

## 🔍 Testing

### Test Phase Detection
```javascript
// In browser console on Sell page
// Select a Doppler knife and check:
console.log(item.phase); // "Ruby", "Phase 2", etc.
```

### Test Price Updates
```bash
# Manually trigger update
POST /api/admin/prices/update

# Check logs for:
# ✅ Fetched X prices for CS2
# ✅ Updated X/Y items
```

### Verify Database
```javascript
// MongoDB shell
db.items.find({ marketPrice: { $exists: true } }).count()
db.items.find({ phase: { $ne: null } })
```

- ✅ `services/pricing.js` - Pricing service
- ✅ `routes/admin.js` - Admin API endpoints
- ✅ `frontend/src/views/AdminPage.vue` - Admin panel UI

- ✅ `routes/inventory.js` - Added phase detection, removed hardcoded prices
- ✅ `services/pricing.js` - Removed all hardcoded price logic

- ✅ Admin panel component ready

---

## ⚠️ Important Notes

### No More Hardcoded Prices
- Items without market data **will not show prices**
- This is intentional - only real prices now
- Run price update to populate prices

### First-Time Setup
1. Run `node make-admin.js` to become admin
2. Restart backend server
3. Go to admin panel
4. Click "Update Prices Now"
5. Wait for completion
6. Prices now populated!

### Rate Limits
- Free tier: 100,000 requests/month
- Each update uses 1 request per game
- Default: 2 requests/hour (CS2 + Rust)
- Monthly: ~1,500 requests (well within limit)

---

## 🎓 Next Steps

### Immediate (Do Now)
1. ✅ Run `node make-admin.js`
2. ✅ Restart backend
3. ✅ Go to http://localhost:5173/admin
4. ✅ Click "Update Prices Now"
5. ✅ Test Sell page with real prices

### Short Term
- Monitor price coverage (% of items with prices)
- Check items without prices regularly
- Adjust update frequency if needed
- Add caching for frequently accessed prices

### Long Term
- Implement Redis caching
- Add price history tracking
- Create price charts/trends
- Add email alerts for failed updates

---

## 🐛 Troubleshooting

### "Admin access required"
```bash
# Run this command:
node make-admin.js

# Then restart backend
```

### "No prices available"
```bash
# Trigger price update via admin panel
# Or via API:
POST /api/admin/prices/update
```

### Items not showing prices
- This is normal if market data doesn't exist
- Not all items are on Steam market
- Check "Items Without Prices" in admin panel

### Update failing
- Check STEAM_APIS_KEY is set
- Verify API key is valid at steamapis.com
- Check rate limits not exceeded
- Review backend logs for errors
