When I invoke the Zoho Books API to retrieve a specific contact (https://books.zoho.com/api/v3/contacts/2888473000000074161) the response is a single contact with all details including billing_address, shipping_address, etc.  When I retrieve all contacts (https://books.zoho.com/api/v3/contacts) the response is a list of contacts containing only the basic contact information without the addresses or contact persons.  If I want to retrieve all contacts including the address information how do I do that through the API?  Do I really have to retrieve all basic contacts and make an extra API call for each one of them?  I've read that there's a limit to the number of API calls which can be made, so if I have hundreds of contacts then that limit may be reached.
