Added comprehensive test coverage (17 test cases) - Implemented custom exception classes for better error handling - Added logging mechanism with configurable levels - Implemented caching with TTL support - Added bulk domain lookup functionality - Created CLI command for domain lookups - Set up GitHub Actions CI/CD pipeline - Configured PHPStan for static analysis - Added code coverage reporting with Codecov Testing & Quality: - Expanded test suite covering rate limiting, pagination, retry logic - Added configuration validation tests - Added PHPUnit configuration with coverage reporting - Integrated PHPStan with Larastan for Laravel-specific checks - Multi-version PHP testing (8.0, 8.1, 8.2, 8.3) Features: - Rate limiting enforcement (1 req/2s) - Automatic retry mechanism with exponential backoff - Response caching with configurable TTL - Bulk domain processing with error handling - CLI command with pagination and force refresh options - Comprehensive logging for debugging Documentation: - Updated README with feature list - Added usage examples for all features - Included exception handling examples - Added troubleshooting section - Documented CLI commands - Added API response format documentation Configuration: - Added logging toggle - Added cache enable/disable option - Added cache TTL configuration -
