Broker’s API access rate limits breached
Last updated 20 June 2026
Broker’s API access rate limits breached
This error means the API rate limit set by your stock broker was reached. It is very unlikely on AutoTrader Web, because our own API limits are stricter than the broker's. So far we have seen it only with Angel Broking's Smart API, where a bug in their limit check was found and reported. If you see it for any other broker, please tell our support team.
What this error means
Every API provider sets API limits. These limits are restrictions that a service provider puts on how often you can call its API. The main reason is to protect servers from too much load. We also apply our own API limits to our users.
This error says that the API limit set by your stock broker was breached by AutoTrader Web. This is a very unlikely case. Our own API rate limits are more stringent than the broker’s limits, so requests usually get held back before they reach the broker’s ceiling.
Solution
So far, we have only seen this with Angel Broking’s Smart API. After a careful study, we found a bug in the Smart API rate limit check. We have reported it to their team, and they are investigating it.
If you see a similar error for any other broker, please inform our support team.
