we have the same requirement. I have not found any evidence if there is an API for this...
I did find a possible workaround on microsoft.com site:
https://techcommunity.microsoft.com/t5/microsoft-forms/api-to-access-ms-forms/m-p/1463830 "use a flow in Power Automate to save each form response to a list in SharePoint. You can either see the last week's responses there or you could have another flow with a recurrence schedule trigger set to 1 week. That would get the items created in the list in the last week and do whatever you want to do with it"
