If you exhaust your monthly token allocation before the reset date, you can purchase top-up token packs at any time. Top-up tokens are used after your monthly allocation is depleted and do not expire.
Purchasing a token pack
Go to Billing in the sidebar.
Click Purchase Tokens.
Select a token pack size.
Review the total and click Confirm Purchase.
The tokens are added to your account immediately.
Token pack pricing
Token packs are priced per million tokens. Larger packs offer a lower per-token rate. Current pricing is shown on the Purchase Tokens page.
Do top-up tokens expire?
No. Top-up tokens remain in your account until they are used. They carry over indefinitely, unlike monthly plan tokens (which do roll over, but only for one month on paid plans).
How tokens are consumed
Your monthly plan allocation is consumed first. Once it is depleted, top-up tokens are consumed. You can see your current balance — plan tokens vs top-up tokens — on the Billing → Usage page.
