I am using Sitecore 8.2 update 3 with Azure search service(Basic) in our application. While rebuilding the index,we get below error.

7980 08:34:38 INFO Schema synchronization failed Exception: Sitecore.ContentSearch.Azure.Http.Exceptions.AzureSearchServiceRESTCallException Message: Error while search service call, see details in message Source: Sitecore.ContentSearch.Azure at Sitecore.ContentSearch.Azure.Http.SearchServiceClient.EnsureSuccessStatusCode(HttpResponseMessage response) at Sitecore.ContentSearch.Azure.Http.SearchServiceClient.GetIndex() at Sitecore.ContentSearch.Azure.Schema.SearchServiceSchemaSynchronizer.RefreshLocalSchema() at Sitecore.ContentSearch.Azure.Http.SearchService.SyncSchema(Object state)

Nested Exception

Exception: Sitecore.ContentSearch.Azure.Http.Exceptions.AzureSearchServiceRESTCallException Message: {"error":{"code":"","message":"You are sending too many requests. Please try again later."}}

I went through the Azure documentation for search-limits-quota-capacity but i don't find maximum number of requests we can make to Azure. https://docs.microsoft.com/en-us/azure/search/search-limits-quotas-capacity

Number of fields is less than 1000 and Batch size is set to 100 in our application.

How can i check the number of service requests we have made ?
