403 Access denied

wish

I am currently facing issues with multiple data APIs, including the Historical Data API, Quotes API, and Gainers/Losers API.

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:

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

Any guidance would be greatly appreciated. Thank you!
