Simple token pricing
The mini cpm API uses a transparent pay-per-token model. You pay $0.15 per 1 million input tokens and $0.50 per 1 million output tokens. This structure ensures you never pay for capacity you do not use. Unlike subscription services that charge for idle time, our prepaid balance tracks actual usage.
Errors and refusals are free. If the model fails or returns an empty response, you are not charged. This means your credit is spent only on successful, usable text. The math is straightforward: divide your token count by one million, multiply by the rate, and sum the input and output costs. You always know exactly what a request will cost before you send it.
Crypto top-up bonuses
Top up your balance using cryptocurrency to receive bonus credit. We accept USDT on TRC20 or USDC on Base. Minimum top-ups start at $20, and you can add up to $500 at a time. The system adds bonus credit automatically to your account.
You receive a 5% bonus on top-ups of $50 or more. A $100 top-up grants a 10% bonus, while amounts of $200 or higher earn a 15% bonus. This bonus credit is treated exactly like your base balance. It never expires and can be used for any request. You get more computing power for the same amount of crypto, lowering your effective cost per token.
Refund policy and prepaid credit
Prepaid credit is non-refundable but it never expires. Once you buy credit, it sits in your account until you use it. This eliminates the risk of monthly fees or subscription renewals. You control exactly when to spend your funds.
If you experience a technical error, such as a double charge, you can request a correction via the Support page. The balance adjusts manually to reflect your actual usage. Since the credit does not expire, you have unlimited time to use it. This structure is ideal for developers who want predictable costs without the hassle of managing recurring billing cycles.
