• Example code in 3 languages (PHP, JavaScript, Python)
• Error responses follow standard format (RFC 7807)
• Webhook subscriptions supported for order events

Dependencies

• Add comprehensive coding agent instructions for repository onboarding #1.1 Product CRUD API (needs underlying service layer)
