It depends on the method and priority you used for setting a task, and on the overall system load.
To illustrate the difference in methods and priorities, let’s take SERP API. The Standard method takes 5 minutes on average (with 45 minutes guaranteed time) to provide the results for the normal priority and up to 1 minute for the high priority of task execution. If you go with the Live method, results will be delivered in under 11 seconds.
You can find the average turnaround time for all our APIs on the Pricing page as illustrated below.
