Worked examples

  1. Long-context document analysis

    Processing a 20,000-token document with a 2,000-token summary response. Cost: (20,000 / 1,000,000 * $0.25) + (2,000 / 1,000,000 * $1.00) = $0.005 + $0.002 = $0.007.

  2. Standard chat assistant

    A 1,000-token prompt generating a 500-token response. Cost: (1,000 / 1,000,000 * $0.25) + (500 / 1,000,000 * $1.00) = $0.00025 + $0.0005 = $0.00075.

  3. Heavy tool-use execution

    A 5,000-token prompt with complex tool definitions generating a 1,500-token response. Cost: (5,000 / 1,000,000 * $0.25) + (1,500 / 1,000,000 * $1.00) = $0.00125 + $0.0015 = $0.00275.

Token Pricing Rates

Our openai api proxy uses a straightforward per-token billing structure. Input tokens are charged at $0.25 per 1 million tokens, while output tokens are charged at $1.00 per 1 million tokens. This ratio reflects the higher compute cost of model inference compared to prompt processing. There are no additional fees for streaming, function calling, or long context windows up to 64,000 tokens. You only pay for what you actually consume, making it easy to forecast costs for your AI agent or application.

Prepaid Credit & No Expiry

Load credit onto your account and spend it as needed. Unlike subscription models that charge monthly regardless of usage, our prepaid system ensures you never pay for idle time. A key advantage is that your prepaid credit never expires. You can top up occasionally and let the balance sit unused for months without penalty. This approach keeps your spending predictable: your usage can never exceed the amount you have already loaded into your account.

Top-Up Bonuses

We reward larger top-ups with bonus credit that sits in your account alongside your base funds. Adding $50 or more grants a +5% bonus, while adding $100 or more grants a +10% bonus. These bonuses are applied instantly to your balance, effectively lowering your cost per token. There is no limit to how much you can top up, and the bonus credit is used alongside your base funds for all API requests.

Questions and answers

Do I need a credit card to start?

No. Every new account receives $0.50 of trial credit valid for 7 days. You only need an email and password. Crypto (USDT or USDC) payment method is only required when you choose to top up your balance.

What happens if I run out of credit?

Your API key remains active, but requests will fail once your balance reaches zero. You can top up at any time using crypto (USDT or USDC), and your credit will be available immediately for subsequent requests.

Is the trial credit renewable?

No. The $0.50 trial credit is a one-time offer per person. Once the 7-day period ends or the credit is exhausted, you must top up to continue using the service.

Are there any hidden fees or monthly charges?

No. There are no monthly subscription fees, no minimums, and no hidden charges. You pay only for the tokens consumed, and any unused prepaid credit remains in your account indefinitely.
