Monthly budget cap#
You can set a monthly budget cap (₩)per API key. When this month's usage plus the estimated cost of a call would exceed the cap, 402 is returned — so even if a key leaks, the damage stays within the cap.
Key scope restrictions#
Per key, you can restrict the allowed model list. For production keys, we recommend allowing only the models you need — violations return
