Token Rates
We charge strictly per token, reflecting the actual compute used. Input tokens are priced at $0.25 per 1M tokens, while output tokens are $1.00 per 1M tokens. This rate structure rewards longer context windows without penalizing your creative control.
Since we host a single high-context model, you avoid the variable costs often found in routed APIs. You know exactly what each character costs, making budgeting for large-scale text pipelines straightforward and accurate.
Prepaid Credit & Bonuses
Your API usage is backed by prepaid credit. When you top up, you never pay a monthly subscription fee, and your credit never expires. This model ensures that your usage can never exceed what you have loaded, keeping spend predictable.
We offer bonus credits to reduce your effective cost per token. Top up from $50 to receive a +5% bonus, or from $100 for a +10% bonus. These bonuses apply immediately to your balance, giving you more tokens for your budget.
Payment Methods
We accept crypto (USDT or USDC) for top-ups, allowing you to choose the method that fits your workflow. There are no hidden processing fees for standard transactions.
Start with a $10 minimum top-up, or begin with our free trial credit. All transactions are processed securely, and your prepaid balance is available for immediate use once confirmed. This flexibility supports both small-scale experiments and large-scale production pipelines.
Usage Limits & Quotas
Each API key is limited to 300 requests per minute, which is sufficient for most automated pipelines and development workflows. You can regenerate your key at any time if needed.
Request bodies are capped at 8 MB, supporting our 100,000-token context window. Since we offer a prepaid model, you do not need to worry about sudden overage charges; your spending is strictly bounded by your loaded credit. This predictability is essential for integrating our uncensored LLM into your cost-sensitive media pipelines.

Questions and answers
Does my prepaid credit expire?
No, your prepaid credit never expires. You can top up whenever you need, and the balance remains available for as long as you hold it.
How does the trial credit work?
Every new account receives $0.50 of trial credit valid for 7 days. No credit card is required to start, making it easy to test the API's capabilities before committing to a top-up.
Can I exceed my prepaid balance?
No. Our API uses a prepaid model, meaning usage stops once your credit is depleted. This ensures your spend is always predictable and never exceeds what you have loaded.
What payment methods do you accept?
We accept crypto (USDT or USDC) for top-ups. Both methods are processed securely, and there are no monthly subscription fees or hidden costs.
