What I Learned

The primary goal of this project was to master calling real-world APIs in Next.js. I learned how to securely fetch live exchange rate data, implement the conversion algorithm efficiently, and apply API security best practices (like protecting API keys and handling rate limits) to build a robust, production-ready application.
