Spend controls put a hard monthly ceiling on what your workspace can spend, and email you before money runs out. They are for owners and admins who want a firm limit no key or agent can exceed.

​
How it works

Before each new call, Locus checks whether it would push this month’s spend over your limit. This month’s spend counts completed charges plus credits reserved for calls still in progress. The month follows the UTC calendar. Calls already running finish and settle normally. To allow more spending, raise the limit or wait for the next month.

​
Set your controls

An API key can’t raise its own spending ceiling.
