Usage examples
A creative writing assistant summarizing a 20,000 token context window with a 2,000 token output.
Cost = (20,000 / 1,000,000) * $0.15 + (2,000 / 1,000,000) * $0.50 = $0.00300 + $0.00100 = $0.00400.
An uncensored story generator producing a long 16,000 token chapter from a 1,000 token prompt.
Cost = (1,000 / 1,000,000) * $0.15 + (16,000 / 1,000,000) * $0.50 = $0.00015 + $0.00800 = $0.00815.
Token Costs and Rate Limits
The Mimo AI API charges $0.15 per 1 million input tokens and $0.50 per 1 million output tokens. This structure ensures you only pay for actual inference, avoiding the inflated rates of traditional providers. Errors and refusals do not consume your prepaid balance, so you never pay for wasted compute.
Each API key supports up to 300 requests per minute and 8 concurrent requests. The request body limit is 8 MB, which comfortably handles our 100,000 token context window. These limits prevent resource exhaustion while maintaining high throughput for your application.
Prepaid Credit and Crypto Top-ups
Funding your account requires cryptocurrency only. You can top up with USDT on the TRC20 network or USDC on the Base network. Accepted amounts range from $20 to $500 per transaction. Your prepaid balance never expires, allowing you to top up whenever convenient without losing value.
Billing Bonuses and Expiration
Larger top-ups earn you bonus credit automatically. Deposits of $50 receive a 5% bonus. Deposits of $100 receive a 10% bonus. Deposits of $200 or more receive a 15% bonus. These bonuses are added to your balance immediately upon confirmation.
Your prepaid credit does not expire, regardless of the amount. This means you can accumulate credits over time without worrying about monthly fees or subscription renewals. The prepaid model keeps your spend predictable and eliminates surprise charges from usage spikes.
