Worked examples
Generating a 5-minute voiceover script
Cost: (5,000 / 1,000,000 * $0.25) + (3,000 / 1,000,000 * $1.00) = $0.00125 + $0.003 = $0.00425. This covers prompt engineering and script output for a single short segment.
Processing a batch of 100 product descriptions
Cost: (50,000 / 1,000,000 * $0.25) + (150,000 / 1,000,000 * $1.00) = $0.0125 + $0.15 = $0.1625. This calculates the text input for processing and the generated concise summaries.
Long-context dialogue generation
Cost: (12,000 / 1,000,000 * $0.25) + (11,000 / 1,000,000 * $1.00) = $0.003 + $0.011 = $0.014. This example reflects a moderate prompt with a detailed, uncensored response.
Per-Token Rates
We charge strictly for the text your TTS pipeline processes. Input tokens are priced at $0.25 per million, and output tokens at $1.00 per million. This model reflects the compute cost of our uncensored LLM. You pay only for the tokens generated and sent, ensuring costs scale directly with your text volume.
Prepaid Credit & Bonuses
Add funds starting at $10 via crypto (USDT or USDC). We reward larger top-ups with bonus credits: +5% on $50+ and +10% on $100+. Your balance never expires, so you can pause usage between projects without losing your funds. This prepaid structure keeps your spend predictable and avoids monthly subscription surprises.
No Monthly Fees
There are no base fees or required subscriptions. You load credit, use it, and reload when needed. If your project slows down, your unused credit remains available. This pay-as-you-go model is ideal for developers with variable traffic or those testing new TTS integrations before scaling up.

Questions and answers
Do I need a credit card for the trial?
No. New accounts receive $0.50 of trial credit valid for 7 days. You only need an email and password to sign up and get your API key immediately.
Can I exceed my prepaid balance?
No. Your API key stops working once your balance reaches zero. This ensures your spend never exceeds what you have loaded, providing strict cost control for your pipeline.
What happens if I don't use my credit?
Your prepaid credit never expires. You can top up, use a portion for active projects, and return to it months later without losing any funds or bonuses.
Are there hidden fees for streaming or tools?
No. Streaming via SSE and tool/function calling use the same token pricing. You are charged only for the input and output tokens generated by the uncensored model.
