YAHOO api geocode - What is the limit exceeded error code or ErrorMessage retrieved as a JSONObject?

I use Yahoo geocode api in an application for geocoding addresses and i need to log开发者_如何学JAVA every time the geocoding limit is exceeded. Please tell me what error code or error message should i query, by parsing the JSONObject response.

As far as I can see it, you get a "403 Forbidden" as a response when exceeding the rate limit. Additionally I get the following XML:

<?xml
    <Error>
        xmlns="urn:yahoo:api"
        The following errors were detected:\r\n\t\t
        <Message>
            limit exceeded
            </Message>
        </Error>

I hope this helps.
