Node.js Backend Fix & Nifty Feed

I run a site powered by Node.js and I’m facing two priorities right now. First, I have a couple of stubborn API-related failures in the current backend that need to be diagnosed and corrected so every route returns consistent, error-free responses. Second, I’d like to stream real-time stock prices from the Nifty 50 and surface them on selected pages without slowing anything down.

My expectation is that once the fixes and the new data feed are live, the site should pass basic reliability tests (24-hour uptime monitoring, no unhandled promise rejections, and clean logs).

Deliverables
• Resolve 2-3 existing API failures and verify each fix with Postman or similar.
• Integrate a reliable live Nifty 50 real-time stock price feed, whether via WebSocket, REST push, or another proven method, and expose it to the frontend in JSON.
• Run stability checks after deployment and share a concise hand-off note summarising changes and any environment variables that were added.
