Billing & Top-up

Balance, top-ups, payment history and what each request cost. Usage draws down a prepaid balance — there is no monthly platform fee and no subscription.

In the console sidebar (it appears once the feature applies to your account): Billing Open it ↗

Steps

1. Open Billing to see the current balance and what has been spent.
2. Press Top up and choose an amount. Card and crypto are both accepted; the balance is credited once payment settles.
3. Watch the balance land — a top-up is usable as soon as it appears, no waiting period.
4. The Payments tab lists every top-up with its date, amount, credits and status.

Limits and gotchas

• Free credit comes from a welcome campaign, not from signing up. Where one is running you can redeem it once per account; otherwise the first call needs a top-up.
• Requests are billed as they complete. A provider error that produced no tokens is refunded; an error whose response still carried usage, or a stream you disconnect from partway, is charged for what was produced.
• Cached prompt reads bill at a separate, lower rate — see the prompt caching guide for what that does to a bill.
