Some of the simple solutions include
Rotating the user agent used in each request to simulate that each request come from difference devices
A a break between each request: if using background jobs with queuing system like bulljs, we can easily add delay time between each job
Using a rotated proxy to change the source IPs (there are even free solution, e.g. https://proxyscrape.com/)
