Request: http://developer.echonest.com/api/v4/artist/profile?api_key=APIKEY&bucket=news&bucket=blogs&bucket=artist_location&bucket=images&bucket=songs&bucket=genre&bucket=urls&bucket=years_active&bucket=terms&bucket=discovery&bucket=hotttnesss&bucket=familiarity&bucket=discovery_rank&bucket=hotttnesss_rank&bucket=familiarity_rank&format=json&id=ARYVZHB1271F573F3F
Response: {"response": {"status": {"version": "4.2", "code": -1, "message": "Unknown error"}}}
Even an example from the API Method page doesn't work: http://developer.echonest.com/api/v4/artist/profile?api_key=APIKEY&id=ARH6W4X1187B99274F&format=json&bucket=biographies&bucket=blogs&bucket=familiarity&bucket=hotttnesss&bucket=images&bucket=news&bucket=reviews&bucket=terms&bucket=urls&bucket=video&bucket=id:musicbrainz
I double checked the API Key and it matches up to what's assigned on my profile page.
Thanks
