# DVLA API Proxy - Complete ✅

## What's Built:

### Database Schema:
- `tiers` - Tier configurations (name, slug, description, allowed_fields JSON)
- `websites` - Client sites with Sanctum auth + tier_id foreign key + rate limits
- `vehicle_records` - Cached vehicle data (JSON)
- `vehicle_data_sources` - Tracks API fetch timestamps per source (DVLA, future wheel API, etc.)
- `api_requests` - Full audit log (regno, IP, contact data, status)

### Features:
- ✅ Sanctum authentication per website
- ✅ Tier-based response filtering (basic/standard/premium) via separate tiers table
- ✅ Dual rate limiting (cache hits + external API calls)
- ✅ DVLA API integration with caching
- ✅ Contact data logging
- ✅ Extensible for future data sources
- ✅ Filament v4 admin panel for managing tiers, websites, and all other tables

### Tier System:
Three tiers are seeded with different field access levels:
1. **Basic** - 7 fields (registrationNumber, make, colour, fuelType, yearOfManufacture, taxStatus, motStatus)
2. **Standard** - 11 fields (basic + co2Emissions, engineCapacity, euroStatus, markedForExport)
3. **Premium** - All fields (empty allowed_fields array = no filtering)

### Seeded Test Tokens:
- Basic: `1|94SHUnbmPcylqbsvKH834EpcINGfq3MFhxlnXpXpf019e706`
- Standard: `2|G156ggWx1KlaFy1QY0oMTsp4AGfsG0mI1DKk3S0sd570a111`
- Premium: `3|IiMGvK1ECXxtzdIK5wGQeG25yHpkgJcxTh1zdUaD31aaf8ee`
- Dev (bypasses limits): `4|fO9q4YDl8Lu9TonzdmTCAvdEJ1iEBhcClIGiuIBKb58aded7`

### Admin Panel:
Visit **http://dvla-api.test/admin** to manage:
- Tiers (create/edit field access levels)
- Websites (assign tiers, configure rate limits)
- Vehicle Records (view cached data)
- API Requests (audit logs)
- Vehicle Data Sources (cache expiry tracking)


### Test the API:
```bash
curl -X POST http://localhost:8000/api/vehicle-enquiry \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"registration_number": "ABC123", "contact_data": {"name": "John", "email": "john@example.com"}}'
```

All 9 tests passing! Ready to use.
