sunor uses a pay-as-you-go credits system. You top up credits and they are consumed when you create tasks.

​
Credit value

1 credit = $0.01 USD For example, 1000 credits = $10.00 USD.

How billing works

When you submit a task, sunor follows a freeze-then-settle billing model:
1

Credits frozen

When a task is submitted, the required credits are immediately frozen (reserved) from your available balance. This prevents over-spending.
2

Task processes

The task is sent to the upstream AI provider and processed asynchronously.
3

Settlement

  • Success: Frozen credits are permanently deducted from your balance.
  • Failure: Frozen credits are automatically refunded to your available balance.

​
Topping up credits

  1. Go to Dashboard > Billing.
  2. Select a top-up amount.
  3. Complete payment via cryptocurrency (powered by OxaPay).
  4. Credits are added to your account once payment is confirmed.

​
Volume bonus

Larger top-ups earn bonus credits on top of the credits you pay for: The bonus is granted automatically when your payment is confirmed. For example, a $500 top-up gives 50,000 credits + 2,500 bonus = 52,500 credits.
Self-serve top-up is capped at 1,000.For1,000. For 1,000+ volume pricing (including the +12% tier), contact us on Telegram or email support@sunor.cc.

​
Credit expiry

Credits expire 12 months from the date of each top-up. Unused credits after this period are forfeited.

Failed tasks

If a task fails for any reason (upstream provider error, timeout, etc.), the frozen credits are automatically refunded to your available balance. You are never charged for failed tasks.
