Neither the API nor the toolkit web site work properly.
When I don't url-encode, I get nothing back. If I DO url-encode (1220+43+1%2f2+AVE+NE%2c+COLUMBIA+HEIGHTS%2c+MN+55421), this address returned as "101 12th Ave NE, Minneapolis MN", entirely wrong.
When I use the website directly, it doesn't return anything either. So Im guessing the website implementation doesn't URL encode the submission either. Regardless though, I'm most concerned about the entirely incorrect return
