Calculation example
Long text summarization task
For prompt 120,000 tokens and response 2,000 tokens. Calculation: (120,000 / 1,000,000) * $0.25 + (2,000 / 1,000,000) * $1.00 = $0.03 + $0.002 = $0.032.
Context-preserving chat
For prompt 10,000 tokens and response 1,000 tokens. Calculation: (10,000 / 1,000,000) * $0.25 + (1,000 / 1,000,000) * $1.00 = $0.0025 + $0.001 = $0.0035.
Large-scale data processing
For prompt 500,000 tokens and response 10,000 tokens. Calculation: (500,000 / 1,000,000) * $0.25 + (10,000 / 1,000,000) * $1.00 = $0.125 + $0.01 = $0.135.
Pay as you go model
mukenetsu ai has eliminated fixed monthly plans. Instead, it uses a pay as you go model that charges only for consumed tokens. This allows low-cost experimentation during development and accurate cost prediction for production. There is no "use it or lose it" worry like with subscriptions; you can continue using the service as long as there is balance in the account.
Also, you are not automatically billed after using up the topped-up amount, allowing you to complete usage within your pre-set budget. This is the optimal model for teams that want to save resources and strictly manage development budgets.
Token pricing
Input tokens (prompt) are $0.25 per 1M tokens, and output tokens (generation) are $1.00 per 1M tokens. There are no complex model logic fees or additional fees, just pure token-based pricing. This transparent pricing eliminates hidden costs per API call, maximizing visibility of development costs. As an OpenAI-compatible API, you can estimate costs using existing client libraries.
Top up and bonuses
Balance can be topped up with cryptocurrency (USDT, USDC). A bonus balance is granted depending on the top-up amount, supporting more efficient cost management. You can top up from a minimum of $10, with a +5% bonus for $50 top-up and a +10% bonus for $100 top-up. Topped-up credits never expire, and you can add more whenever needed. This allows continuous API usage even for large batch processing or long sessions.
Trial credit
New accounts receive $0.50 of trial credit without requiring card registration. This trial credit is valid for 7 days, allowing you to get an API key and start using it immediately. No phone verification is required, so you can quickly check the performance and interface of mukenetsu ai. This lowers the barrier for developers to immediately verify API functionality and move to production use.
Payment methods
We support top-ups via credit card and cryptocurrency. Balances use a prepaid credit system, allowing you to spend only within the amount you have topped up. This prevents unexpected high bills and makes budget management easier. Additionally, each account has only 1 API key, which can be regenerated as needed. When regenerated, the old key becomes invalid, enabling flexible operations while maintaining security.

Frequently asked questions
What happens when the balance runs out?
API requests are rejected when the balance is empty. The service is unavailable until you top up. Usage completes within your set budget without automatic billing.
Do topped-up credits expire?
Topped-up credits never expire. You can use the funds whenever needed. This allows you to use the service without worrying about balance for long-term projects.
How long is the $0.50 free trial credit valid?
The $0.50 free trial credit is valid for 7 days after account creation. The balance expires after 7 days. However, topped-up credits have no expiry, so you can use them without worry for production.
What happens when I regenerate my API key?
Regenerating the API key immediately invalidates the old key. The new key becomes available instantly. This allows for quick response to key leaks or security policy changes.
You can get an API key with just 1 form
Create an account, copy the key, and change the base URL. That is all it takes to complete the setup.
