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:
Credits frozen
When a task is submitted, the required credits are immediately frozen (reserved) from your available balance. This prevents over-spending.
Task processes
The task is sent to the upstream AI provider and processed asynchronously.
Settlement
- Success: Frozen credits are permanently deducted from your balance.
- Failure: Frozen credits are automatically refunded to your available balance.
Topping up credits
- Go to Dashboard > Billing.
- Select a top-up amount.
- Complete payment via cryptocurrency (powered by OxaPay).
- Credits are added to your account once payment is confirmed.
Credit expiry
Credits expire 12 months from the date of each top-up. Unused credits after this period are forfeited.
Checking your balance
Use the Get Balance endpoint to check your current credits:
curl https://sunor.cc/api/v1/account/balance \
-H "x-api-key: YOUR_API_KEY"
{
"code": 200,
"data": {
"available": 950,
"frozen": 10,
"total": 960
}
}
| Field | Description |
|---|
available | Credits available to spend |
frozen | Credits reserved by in-progress tasks |
total | available + frozen |
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.
