Api Security Hardening

This is a solid foundation for locking down REST APIs with all the essentials in one place: authentication with JWT, rate limiting, helmet for security headers, input sanitization against XSS and NoSQL injection, and proper CORS configuration. You get reference implementations for Node.js/Express, Python FastAPI, and API gateway setups. Use this when you're hardening an existing API before going to production or building a new one that needs to pass a security audit from day one. The quick start example pulls together the usual suspects (helmet, express-rate-limit, xss-clean) so you don't have to remember which npm packages to combine. It won't write your security policy for you, but it handles the technical implementation of common defenses.
