Rest API call threshold before it impacts ePO performance

[JKBH1]

A few questions regarding the REST API calls based on this guide: https:/docs.trellix.com/bundle/data-loss-prevention-11.10.x-product-guide/page/GUID-8F26CFD5-8213-41AB-8957-39EB854BB4A1.html

Is there a threshold for concurrent rate of API calls until it would impact ePO's performance?

For example, if I want to know that there are new incidents that came in for the past 15 minutes, I'd create an API call to check this data, say probe ePO DLP incidents every second. Would this impact backend/ePO performance?

I was hoping to create a query for this, where last incident occurrence was within the last 15 minutes. However in Queries and Reports, found this Last Update properties but minimum is 1 hour and there is no option for minutes. I'd have an API call probe on this query so it doesn't have to check every second that a new DLP incident has been generated. 

New to the API world. I don't want to run concurrent API calls and set ePO to rest in peace. Any insights, recommendations or best practices would be helpful. Thank you.
