Azure DevOps connector subscription cost

Hi,
I have created power automate flow with Azure Devops premium connector and its working fine with that, but as it seems that Azure DevOps is premium connector hence wanted to know what is monthly or yearly cost behind it, as currently the flow ia working fine with this connector without any premium subscription. I wanted to know if my flow stop working if I haven't purchase the subscription.
What is cost for azure devops premium connector user in power automate flow

Thanks in advance
