"it is a good idea to turn off automatic preview updating so API calls are not made too often. Too many API calls can sometimes lead to temporary blockages, and may require waiting periods before they can be used again. "

Can anyone provide me further explanation on the bolded text?

Companies providing access to their data via APIs can decide to throttle/block a user if they are hitting their servers too often with requests for data.

It’s a means of protecting their services from being overwhelmed.
