Cautions
- NSE APIs require a session cookie obtained by first visiting
https://www.nseindia.com— always initialize the session before API calls - NSE may rate-limit or block automated requests; add a small delay between calls if running bulk scans
- Market data is available only during trading hours (Mon–Fri, 9:15 AM – 3:30 PM IST)
- API endpoints and response structure may change — verify against NSE website if calls fail
