How prepaid credit works
Your balance updates in real-time. We charge based on actual token usage, not estimated tokens. If your request fails or returns an error, we do not charge you. This prepaid system keeps your spending perfectly predictable. You never pay for unused capacity.
Trial credit details
Every new account starts with $0.50 of trial credit. This credit is valid for 7 days. It is perfect for testing integration with your Silly Tavern setup. The trial uses the same uncensored model as paid accounts.
Why prepaid keeps spend predictable
Subscription models often charge for idle time. Prepaid credit ensures you only pay for active inference. You can top up exactly when needed. Our crypto-only payments from $20 to $500 prevent unexpected monthly bills. Errors and refusals are always free.
