IP has been blocked as you have exceeded the maximum number of requests per minute

Hi,

when using zoho invoice API I get erro message "For security reasons your IP has been blocked as you have exceeded the maximum number of requests per minute that can originate from one IP address." How long  the IP Address  will be blocked?

And where can I see my current amount of API calls for zoho invoice.
