There is no API restriction. however, if we see an abnormal peak in API requests, we may suspend your account temporarily (usually for one hour).
In case of a suspension, you will be notified immediately by an automated email and the API will be temporarily disabled as well (403 HTTP code).
Sometimes a script bug that you didn't know about can cause this kind of problem, so we want to make sure everything is fine on your side first. Please contact us if you have any questions regarding this matter.
