## 🔴 Critical API Issues (Blocking Production)

### 1. Vehicle Creation Endpoint Mismatch
- **Frontend Calls:** `/api/v1/vehicles/register` (404 Not Found)
- **Backend Has:** `/api/v1/assets/vehicles` (requires authentication)
- **Impact:** Users cannot add vehicles to their garage
- **Fix Required:** Update frontend or create redirect endpoint

### 2. Catalog Endpoints Missing
- `/api/v1/catalog/brands` - 404 (vehicle brand listing)
- `/api/v1/catalog/models` - 404 (model search)
- `/api/v1/vehicles/search/brands` - 404 (alternative endpoint)
- **Impact:** Vehicle selection UI shows empty dropdowns
- **Fix Required:** Implement catalog query endpoints

### 3. Expense API 500 Errors
- `/api/v1/expenses` - Returns 500 Internal Server Error
- **Root Cause:** Schema mismatch between `vehicle.costs` and `vehicle.vehicle_expenses`
- **Impact:** Users cannot log maintenance costs
- **Fix Required:** Align database relationships and API response models

### 4. Authentication Endpoint 404 ✅ FIXED
- `/api/v1/auth/me` - ✅ Now returns user profile (alias for `/api/v1/users/me`)
- **Impact:** Frontend can now validate user session on page load
- **Fix Applied:** Added `/auth/me` endpoint to auth.py returning UserResponse
- **Verification:** Real identity test with admin user confirmed both endpoints work

---

## 🟡 High Priority API Gaps

### 1. Analytics Service Missing
- **Required:** `/api/v1/analytics/tco` - Total Cost of Ownership calculations
- **Required:** `/api/v1/analytics/fleet` - Fleet-wide metrics
- **Impact:** Dashboard tiles show mocked data only

### 2. Admin Control Panels Incomplete
- Gamification rule management endpoints missing
- System parameter bulk update endpoints
- User moderation endpoints

### 3. Historical Data Support
- `occurrence_date` field not consistently implemented
- Missing endpoints for historical cost analysis
- Impact: Cannot track cost trends over time

---

## 🟢 Medium Priority API Gaps

### 1. Webhook & Notification Endpoints
- Event subscription management
- Notification preference endpoints

### 2. Bulk Operations
- Batch vehicle import
- Mass expense entry
- Fleet-wide updates

### 3. Advanced Search Endpoints
- Complex vehicle search with multiple filters
- Service provider ranking algorithms
- Geographic clustering endpoints

---

## 🔧 API Health Check Results

### Working Endpoints (Verified)
```bash
✅ GET    /api/v1/auth/login
✅ POST   /api/v1/auth/register  
✅ GET    /api/v1/users/me
✅ GET    /api/v1/assets/vehicles
✅ GET    /api/v1/services
✅ GET    /api/v1/gamification/leaderboard
✅ GET    /api/v1/finance/wallets
```

### Broken Endpoints (Require Fix)
```bash
❌ GET    /api/v1/vehicles/register          # 404 - Wrong endpoint
❌ GET    /api/v1/catalog/brands            # 404 - Missing implementation
❌ POST   /api/v1/expenses                  # 500 - Schema mismatch
✅ GET    /api/v1/auth/me                   # ✅ Fixed - Returns user profile
```

## 🎯 Immediate API Implementation Priorities

### Phase 1 (Critical - Blocking)
1. **Fix vehicle creation flow** - Align frontend/backend endpoints
2. **Implement catalog endpoints** - Enable vehicle selection UI
3. **Repair expense API** - Fix 500 errors for cost logging

### Phase 2 (High Priority)
4. **Add analytics endpoints** - Enable real dashboard data
5. **Complete admin endpoints** - Gamification and system controls
6. **Implement historical data** - `occurrence_date` support

### Phase 3 (Medium Priority)
7. **Webhook system** - Event-driven notifications
8. **Bulk operations** - Data import/export
9. **Advanced search** - Complex query capabilities
