Credits & Top-Up

ai& uses a prepaid credit model. You add credits to your organization, and inference requests deduct from that balance as they complete.

Purchasing credits

1. Go to console.aiand.com/settings/billing.
2. Click Purchase Credits and choose an amount.
3. Optionally apply a Coupon.
4. Pay via Stripe Checkout.

The balance is credited immediately on successful checkout. Stripe webhooks confirm the payment; if a charge later fails, the corresponding credits are reversed.

How charges work

• Each request is billed when it completes, computed from input + output tokens.
• The cost is deducted atomically — concurrent requests can’t overdraft.
• See Pricing for per-model rates.

What happens at zero balance

When your balance reaches zero, new inference requests return 402 Payment Required with a clear error. Existing in-flight requests complete and may push the balance slightly negative; the next top-up zeroes that out before adding new credit.

Tip

Credits don’t expire. See Refund Policy for return and chargeback rules.
