Data API - “API not found” 404 errors on Gov? Are these endpoints live?

Data API throwing “API not found” errors for multiple Gov endpoints:

• https://api.moveworksgov.ai/export/v1beta2/records/interactions 
• https://api.moveworksgov.ai/export/v1beta1/records/interactions
• https://api.moveworksgov.ai/export/v1/records/interactions 

{
  "error": {
    "code": "NOT_FOUND",
    "message": "API not found"
  }
}

OAuth 2.0 token is working as expected (works with other APIs endpoints such as Events (previously) and Webhooks)

This also fails from Data API tool: https://help.moveworks.com/reference/get_interactions-1

Question: Why might this be occurring? Are these endpoints live?
