来自亚马逊实例的Google API调用

Am using the amazon instances to call the google shortener URL API. whenever i calls the server it returns the below error

(
    [error] => stdClass Object
        (
            [errors] => Array
                (
                    [0] => stdClass Object
                        (
                            [domain] => usageLimits
                            [reason] => rateLimitExceeded
                            [message] => Rate Limit Exceeded
                        )

            )

        [code] => 403
        [message] => Rate Limit Exceeded
    )

)

Please assist me to fix this issue.Thanks in Advance.

That error typically reflects a quota limit being exceeded, or a client sending too many unbatcheded requests at once. Unless you activate billing, your rate will be limited.
