As is detailed when you unsubscribe from an API in the dashboard, your access to that API will be cut off immediately. Any requests to the API will stop working without an active subscription. If you need to continue using the API we recommend maintaining your subscription for as long as you need then only unsubscribing when you are finished. If this ends the subscription mid-plan and you would like to request a prorated refund you can contact support. Please see our article about refunds here.
