+## API limits
+
+All requests through NSE are rate limited or throttled to 3 requests per second. This allows making large number of requests without overloading the server or getting blocked.
+
+- If downloading a large number of reports from NSE, please do so after-market hours (Preferably late evening).
+- Add an extra 0.5 - 1 sec sleep between requests. The extra run time likely wont make a difference to your script.
+- Save the file and reuse them instead of re-downloading.
