Create a new Express API endpoint with full integration.

Generate:

• Express route handler in /server/api with TypeScript
• Input validation using express-validator or Zod
• Comprehensive error handling middleware
• CORS configuration in Express app
• Database integration with Prisma ORM
• Request/response TypeScript interfaces
• API client code in Next.js (/lib/api) for calling the endpoint
• Environment variable configuration
• Example usage in a Next.js component
• API documentation comments

Include proper middleware chain (validation, authentication, error handling), logging, security headers, and RESTful conventions. Ensure rate limiting and request validation are in place.
