It's a good question. As our service is delivered through a utility pricing model, most of our API requests are billing events - each call, text message or recording ends up having a debit to the account balance associated with it.

That said, we do have the monitoring you describe in place which is how we were alerted to the incident and limited the damage to 1.4% of the account base.
