Simple prepaid token pricing
You pay strictly for what you consume, so your spend matches your actual usage without hidden monthly fees. This prepaid model ensures every dollar goes toward token generation rather than infrastructure overhead.
No subscription. Prepaid balance does not expire.

Usage examples
A developer testing a 3,000-token prompt with a 1,000-token response.
Input cost: 3,000 / 1,000,000 * $0.15 = $0.00045. Output cost: 1,000 / 1,000,000 * $0.50 = $0.00050. Total: $0.00095. You can run over 1,000 of these requests for just under $1.00.
An AI agent processing a 50,000-token context window with a 2,000-token output.
Input cost: 50,000 / 1,000,000 * $0.15 = $0.0075. Output cost: 2,000 / 1,000,000 * $0.50 = $0.0010. Total: $0.0085. This precise calculation means you know exactly how many long-context runs your budget supports.
A script generating short 200-token answers from a 500-token prompt.
Input cost: 500 / 1,000,000 * $0.15 = $0.000075. Output cost: 200 / 1,000,000 * $0.50 = $0.00010. Total: $0.000175. Small tasks accumulate cheaply, making this ideal for high-volume, low-latency workflows.
How prepaid billing works
Your balance deducts only when the model successfully generates a token. Errors consume no credit, and refusals for content policy violations are free. This structure removes the risk of paying for failed requests or empty responses.
You top up using crypto, and the credit never expires. There is no monthly fee to maintain access, so you can pause usage for weeks without losing your account status. The balance simply sits there until you need it.
Since we charge per token, you only pay for the actual compute used. This transparency makes budgeting straightforward for both small experiments and large-scale deployments.
Crypto top-up options
We accept USDT on the TRC20 network and USDC on the Base network. You can deposit any whole amount between $20 and $500 per transaction. The process is direct: send the crypto, receive the credit, and start making requests immediately. Your account remains active as long as you have a positive balance.
Using crypto eliminates the friction of recurring billing cycles. You control exactly when you add funds, ensuring your spending aligns with your current project needs rather than a fixed monthly schedule.
Bonus credit structure
Large deposits earn you extra credit that boosts your purchasing power. A $50 top-up includes a 5% bonus. A $100 deposit adds 10% extra credit to your balance.
If you deposit $200, you receive a 15% bonus. This means you get more tokens per dollar spent compared to smaller transactions. The bonus is applied immediately upon confirmation of the crypto transfer.
These bonuses are designed to reward consistent usage. Higher volume deposits reduce your effective cost per token, making this option ideal for teams running continuous workloads or long-running experiments.
Free errors and refusals
If the API returns an error or the model refuses a request due to content policy, you are not charged. This includes timeouts, server errors, and content refusals. You only pay for tokens that are successfully generated and delivered.
This policy protects you from unexpected costs during debugging. You can test your prompt engineering without worrying about wasting credit on failed attempts. Errors are common in development, and this pricing model accommodates that reality.
Your prepaid balance reflects only successful completions. This ensures that your spending is directly correlated with the value you receive from the model's output.
