What this error means
Claude rejects the request when the account has spent its included plus extra usage allowance for the period.
How to fix it
- Add or raise the extra usage limit at claude.ai
- Switch that agent to an API-key provider with credit
- Fall back to a cheaper model for low-stakes calls

"type": "error",

"message": "You are out of extra usage. Add more at claude.ai to keep going."
}
}Frequently asked
Is this a billing or a rate error?
Billing. It clears when you raise the usage cap or the billing period resets, not by retrying.
