Worked examples
Short code completion
A 2,000 input token prompt generating 200 output tokens costs: (2,000 / 1,000,000 * $0.25) + (200 / 1,000,000 * $1.00) = $0.0005 + $0.0002 = $0.0007.
Medium-length analysis
A 10,000 input token request producing 1,000 output tokens costs: (10,000 / 1,000,000 * $0.25) + (1,000 / 1,000,000 * $1.00) = $0.0025 + $0.001 = $0.0035.
Long context document
A 50,000 input token request generating 5,000 output tokens costs: (50,000 / 1,000,000 * $0.25) + (5,000 / 1,000,000 * $1.00) = $0.0125 + $0.005 = $0.0175.
Transparent Token Pricing
The uncensored api uses straightforward rates: $0.25 per million input tokens and $1.00 per million output tokens. Input tokens cover the prompt sent to the model, while output tokens represent the generated response. Errors and refusals do not incur charges, ensuring you only pay for successful generation.
Prepaid Credit Model
Top up your account with crypto to receive prepaid credit. This credit never expires, allowing you to use the pay per token api at your own pace. The prepaid balance keeps spending predictable because usage cannot exceed the loaded amount. Errors are free, and the balance updates in real-time as tokens are processed.
Crypto Top-Up Options
Support for crypto api billing via USDT (TRC20) and USDC (Base) allows for quick top-ups. Payments range from $10 to $500 in whole amounts. Sign up with Google or email to get your key immediately, with no card required. This direct billing method ensures fast processing without traditional payment delays.
Questions and answers
How is the cost calculated?
Cost is calculated by dividing input tokens by 1,000,000 and multiplying by $0.25, then adding the output token cost (output tokens / 1,000,000 * $1.00). Errors do not add to the cost.
Does the prepaid credit expire?
No, the prepaid credit never expires. You can top up whenever you like and use the funds over time without worrying about monthly resets.
Can I get a refund on my credit?
Credit is not refunded. If a mistake like a double charge occurs, you can fix it through the Support page. The credit remains available for future requests.
How do I top up my account?
Top up using USDT on TRC20 or USDC on Base. Payments must be whole amounts between $10 and $500. You can also start with a $0.50 trial credit, no card needed.
