Hello,
Unfortunately, it is not possible to check the number of calls made to the API. You can keep track of the operations you have performed and count them every time while making the API call. You could refer
this guide to count the API operations.
You will face the
RateExceededError when too many requests were made to the API in a short period of time or performing more than 10,000 operations in a day with
Basic access. If you are facing the error due to account scope, then you have to wait for about 30 seconds, then retry the request. If you are facing the error due to developer token access level then you might have to upgrade your token to
standard access (if you currently have basic) or wait until the following day.
