Is there a way to check if a user has an active subscription?

We have a Chamber of Commerce site that the members need an active subscription to be able to access their GD listing. We are also using GD CPT for the members to be able to post jobs and maybe will switch our events to GD CPT as well. I want to be able to restrict their ability to post jobs and events if their membership is not active. The only thing that I can see to be able to determine if a membership is active is a current subscription for the Place listing. So I am hoping there is a global variable or function that I can check if the user has a current, active subscription. If they don’t, then I would restrict access to the add job posting and add event posting interfaces.
