Every API key and every assistant connection has a daily spend cap in credits. The default for a new connection is £50.
What happens at the cap
An ask that would take the connection past its cap is refused with spend_cap_exceeded. The error says how much is left and when the cap resets. Nothing is spent. Reading results still works.
Checking what's left
The balance tool and GET /v1/billing/balance return capRemaining for the key or connection you're using. A well-behaved agent checks before it asks, but the cap is enforced whether it checks or not.
Changing a cap
In Developers, edit the key or connection and set a new daily cap. The change takes effect straight away.
Warnings
We email you when a connection reaches 80% of its cap in a day, or when a new assistant connects. Turn these off in Settings, then Notifications.
Account limits
Caps on keys sit inside your account's own limits: an agent can never spend more than your balance.
