You can access information about API requests for your account in Usage Analytics, under the API Requests section.
There are two tabs for Usage Analytics. The account tab shows data for your individual account, whereas the workspace tab covers all accounts under your workspace. Unless you're on an Enterprise plan, the data will be the same across the two tabs.
In the API Requests section, you’ll find not only the total number of requests made within a specific timeframe but also the number of concurrent requests during that period.
You can view data by different time periods, for example, hour, day, month and year, and at different levels of granularity.
