Can someone tell me why the following query will work within the YQL Console:

'SELECT * FROM social.profile WHERE email="joestier3@yahoo.com"';

[link]
http://developer.yahoo.com/yql/console/#h=%20SELECT%20*%20FROM%20social.profile%20WHERE%20email%3D%22joestier3@yahoo.com%22


But the same query will not work when I run it using the PHP API?

Here is the response I get:
stdClass Object (     [query] => stdClass Object         (             ...             [diagnostics] => stdClass Object                 (                     [publiclyCallable] => false                     [redirect] => stdClass Object                         (...)
                    [url] => stdClass Object                         (                             [execution-start-time] => 434                             [execution-stop-time] => 564                             [execution-time] => 130                             [http-status-code] => 403                             [http-status-message] => Forbidden                             [content] => http://social.yahooapis.com/v1/users.email(jmcgraw77%40yahoo.com)/profile;start=0;count=10?format=json                         )
