Questions
Billing, answered
How does the credit system work?
Credits are the platform's unit of account. One US dollar buys 100 credits, so one credit is worth one US cent. Each API response reports the exact number of credits it consumed, and your balance is debited by that amount.
Do credits expire?
No. Credits stay on your balance until you spend them. There is no monthly minimum and no inactivity fee.
What happens if my balance runs out?
Requests are rejected with HTTP 402 and a clear error message. Nothing is charged, and existing keys keep working the moment you top up again.
Can I cap spend per key?
Yes. Every API key can carry an optional credit limit. Once a key reaches its limit it stops authorising requests while your other keys continue to work.
Which payment methods are supported?
Checkout is handled by Whop, which accepts major cards, Apple Pay and platform balance. You are redirected to Whop for payment and returned to your dashboard when it completes.
Do you offer refunds?
Unused credits can be refunded within 14 days of purchase. See the refund policy for the details.
