Question for the RE Agents

[Marquise Crampton]

Hello, I am a new agent and had a question about viewing homes from sights like Zillow. Previous to receiving my license I had gotten in touch with one of the agents on the website and viewed a home. Since then I've received my licence and wanted to continue viewing properties. My question is do only the agents signed with zillow have access to these properties to view or is there a way I can skip the hassle of working with another agent and schedule my own viewing. I know they pay to be promoted on the website, so I'm not sure if this would be considered ethical.  Thanks in advance
