The spend order
Every credit-metered action, managed model usage, web searches, environment hours, and mailboxes, follows the same path.
- 1Monthly credit grant firstEvery plan includes a monthly credit grant (the amount varies by plan). Usage draws it down first, and it resets with the billing period.
- 2Topped-up credits nextWhen the grant is exhausted, or during a trial, usage draws from any credits you have topped up.
- 3Hard stop at zeroWhen both are exhausted, agents pause: LLM calls, web searches, and further environment or mailbox charges stop. Environments and mailboxes stay provisioned, and everything resumes the moment you top up, switch to BYOK, or the grant resets. There is no open-ended metered billing.
