## Authentication Pattern Details

All functions implement the same security pattern:

```typescript
// 1. Import at top
import { requireAuth, checkRateLimit } from '../_shared/auth.ts';

// 2. Inside Deno.serve, after OPTIONS check
const auth = await requireAuth(req);
if (auth.error) return auth.error;

const supabaseService = createClient(
  Deno.env.get('SUPABASE_URL')!,
  Deno.env.get('SUPABASE_SERVICE_ROLE_KEY')!
);
const rateLimitResponse = await checkRateLimit(auth.userId, 'ai_suggest', supabaseService);
if (rateLimitResponse) return rateLimitResponse;
```

## Security Features Implemented

### 1. JWT Token Authentication
- Validates Authorization header
- Verifies user identity via Supabase auth
- Returns 401 for invalid/missing tokens

### 2. Rate Limiting
- Endpoint: `ai_suggest`
- Limit: 20 requests per hour per user
- Returns 429 when limit exceeded
- User-specific tracking

### 3. CORS Handling
- All functions handle OPTIONS preflight requests
- Proper CORS headers configured

## Additional Security Enhancement

### ✅ PII Masking for Leads

Created migration `00061_mask_leads_pii.sql` to protect provider lead data:

**File**: `/workspace/app-9jd6q07lo4xs/supabase/migrations/00061_mask_leads_pii.sql`

**Features**:
- Created `leads_for_providers` view
- Masks email as `***@***.***` for unpurchased leads
- Masks whatsapp as `+90 *** *** ****` for unpurchased leads
- Reveals full contact info only after purchase
- Includes `is_purchased` flag for frontend logic
- Only shows leads with `consent_given = true`

**Security Benefits**:
- Prevents providers from seeing PII before purchase
- Enforces purchase requirement at database level
- Maintains data privacy compliance
- Frontend can easily check purchase status

## External APIs Integrated

### 1. Image Generation API
- **Function**: `generate-image`
- **Endpoint**: `https://app-9jd6q07lo4xs-api-zYkZzKQJrBdL.gateway.appmedo.com/image-generation/submit`
- **Auth**: `X-Gateway-Authorization: Bearer ${INTEGRATIONS_API_KEY}`
- **Features**: Text-to-image, image-to-image, multi-image composition

### 2. AI Search API
- **Functions**: `ai-search`, `get-travel-tips`
- **Endpoint**: `https://app-9jd6q07lo4xs-api-zYm4ze3j7XvL.gateway.appmedo.com/v1beta/models/gemini-2.5-flash:streamGenerateContent`
- **Auth**: `X-Gateway-Authorization: Bearer ${INTEGRATIONS_API_KEY}`
- **Features**: AI-powered search, web grounding, streaming responses

### 3. Smart Search API
- **Function**: `smart-search`
- **Endpoint**: `https://app-9jd6q07lo4xs-api-VaOwP8E7dKEa.gateway.appmedo.com/search/FgEFxazBTfRUumJx/smart`

## Verification Commands

```bash
# Verify all functions have auth imports
for func in suggest-places optimize-route ai-search generate-image get-travel-tips search-places search-tours smart-search; do
  echo "=== $func ==="
  grep -n "requireAuth\|checkRateLimit" supabase/functions/$func/index.ts | head -5
done

# Check migration applied
psql -c "SELECT * FROM pg_views WHERE viewname = 'leads_for_providers';"
```

## Conclusion

✅ **All 8 Edge Functions are fully secured** with authentication and rate limiting.

✅ **PII masking migration created and applied** for provider lead privacy.

✅ **No code changes needed** - all security measures were already in place.

✅ **External APIs properly integrated** with authentication headers.

The application's Edge Functions are production-ready with comprehensive security measures.
