Writing a long technical report with moderate tool usage
Input: 20,000 tokens (cost $0.003). Output: 4,000 tokens (cost $0.002). Total: $0.005. Formula: (20,000/1,000,000 * 0.15) + (4,000/1,000,000 * 0.50) = 0.003 + 0.002 = 0.005.
Processing a large codebase for refactoring
Input: 50,000 tokens (cost $0.0075). Output: 1,000 tokens (cost $0.0005). Total: $0.008. Formula: (50,000/1,000,000 * 0.15) + (1,000/1,000,000 * 0.50) = 0.0075 + 0.0005 = 0.008.
Generating a short creative story
Input: 500 tokens (cost $0.000075). Output: 2,000 tokens (cost $0.001). Total: $0.001075. Formula: (500/1,000,000 * 0.15) + (2,000/1,000,000 * 0.50) = 0.000075 + 0.001 = 0.001075.
How prepaid credit works
You top up with USDT (TRC20) or USDC (Base), with whole amounts from $20 to $500. Your balance never expires, so you can pause usage without losing funds. Errors and refusals cost nothing, so your credit reflects actual value delivered.Why prepaid billing suits developers
Subscriptions force you to pay for idle time, but prepaid credit matches your actual consumption. You only spend what you use, and any remaining balance stays in your account. This model eliminates monthly surprises and keeps your LLM costs predictable. You can top up whenever you want, with no minimum commitment.
Bonus credits on top-up
We reward larger top-ups with bonus credit. Deposits of $50 get a +5% bonus, $100 gets +10%, and $200 gets +15%. These bonuses are added to your prepaid balance and last forever. You never lose your original credit, and the bonus extends your usable range for more requests.
Common questions
Does my prepaid credit expire?
No, your prepaid credit never expires. You can top up today and use the funds months or years later. Errors and refusals are free, so your balance only decreases when you get actual responses.
What happens if I get a 401 error?
A 401 error means your key is invalid or expired, not that you were charged. You still have your full prepaid balance. We fix double charges or errors through the Support page, and your credit remains safe.
Which payment methods do you accept?
Crypto only: USDT on TRC20 or USDC on Base, any whole amount from $20 to $500. Bonus credit applies from $50.
Is there a minimum amount to top up?
Yes, the minimum top-up is $20. You can pay any whole amount up to $500. Each top-up adds to your existing balance, which never expires, so you can accumulate credit over time without losing it.
