Topic: Api not work?

I am a developer and want to test your great api,
but I failed to request the url handle_url_tag('http://ope-api.pho.to/queued.php?key=3CCREZBSFGLPUYAXT7RJL6KEF6EB&image_limit=watermark&image_url=%20http://pho.to/img/soft/ope/samples/17.jpg%20&methods_list=caricature:type=13') with error 403.

Is it still working?
