For example, while making the following request:

method: 'post',
url: 'https://apiconnect.angelone.in/rest/secure/angelbroking/historical/v1/getCandleData',
data: '{"exchange":"NSE","symboltoken":"10940","interval":"ONE_DAY","fromdate":"2026-04-28 09:30","todate":"2026-05-04 09:30"}',

I receive the following response:

• Status: 403
• Message: "Access denied because of exceeding access rate"

What is confusing is that this error occurs within the first few requests itself, so it does not appear to be a typical rate limit breach.

Could you please clarify:

1. Are there any undocumented that might be triggering this?
2. What is the cooldown or penalty duration once the rate limit is exceeded?
3. Could this error also be caused by authentication/session-related issues?

Any guidance would be greatly appreciated. Thank you!
