A 20,000 token prompt requiring a 2,048 token JSON response
<p>Cost = (20,000 × 0.00000015) + (2,048 × 0.00000050) = $0.00300 + $0.001024 = $0.004024.</p>

<p>Cost = (50,000 × 0.00000015) + (10,000 × 0.00000050) = $0.00750 + $0.00500 = $0.01250.</p>
Prepaid credit mechanics and expiry
Prepaid credit never expires, so you can top up once and use it over months. Your balance deducts only when tokens are successfully generated. Errors and refusals cost nothing. We do not offer a monthly subscription, so there are no recurring charges. You pay exactly for what you use. This prepaid model keeps your LLM API pricing predictable. You can top up at any time without waiting for a billing cycle.
Trial credit and account setup
Every new account receives $0.50 of trial credit valid for 7 days. You can sign up with Google or an email password. The trial credit works like your prepaid balance. It deducts based on token usage. You can use it to test the API before buying more. Refunds are not available for prepaid credit. Mistakes are handled via the support page.
Why prepaid balances control spend
A prepaid balance prevents surprise bills. You know exactly how many requests your budget allows. This is vital when running high-volume automation. The prepaid model eliminates monthly subscription traps. You only pay for successful token generation. Errors are free. This makes the API ideal for developers who want strict cost control. You can top up with crypto whenever you need more. The prepaid credit is the only way to use our service.
