Worked examples

Post-processing a 1-hour podcast transcript

Input: 60,000 tokens (transcript from your speech to text api). Output: 40,000 tokens (cleaned, formatted JSON). Cost: (60,000 * $0.00000025) + (40,000 * $0.000001) = $0.015 + $0.04 = $0.055.

Generating captions for 50 short videos

Input: 10,000 tokens (raw ASR text). Output: 12,000 tokens (synchronized captions). Cost: (10,000 * $0.00000025) + (12,000 * $0.000001) = $0.0025 + $0.012 = $0.0145.

Extracting structured data from 100 legal documents

Input: 200,000 tokens (long context window usage). Output: 50,000 tokens (JSON extraction). Cost: (200,000 * $0.00000025) + (50,000 * $0.000001) = $0.05 + $0.05 = $0.10.

Transparent Token Pricing

We charge strictly for tokens processed, not for API calls or uptime. Input tokens are priced at $0.25 per 1M tokens, while output tokens (the LLM's response) are $1.00 per 1M tokens. This structure reflects the higher compute cost of generation. Because our model is uncensored and handles complex post-processing tasks, you get precise billing for the actual work done. There are no hidden fees for streaming or tool calling. You only pay for the tokens that enter and leave our API.

Bonus Credits

When you top up your prepaid balance, you receive bonus credit based on the tier of that specific transaction. Top-ups of $50 or more include a 5% bonus, while top-ups of $100 or more include a 10% bonus. These bonuses are applied to the total value loaded in that specific transaction, not just the incremental amount above the threshold. For example, a $100 top-up gives you $100 in base credit plus $10 in bonus credit. Bonus credits do not expire and can be used to pay for any token usage.

No Hidden Fees

Our pricing model is designed for developer predictability. There are no monthly subscriptions, no setup fees, and no charges for API key regeneration. You can switch between streaming and non-streaming responses without any cost difference. The only limit is your prepaid balance. Once your balance reaches zero, your API key stops working until you add more credit. This ensures you never receive a surprise bill at the end of the month. Your usage can never exceed what you have already loaded.

Prepaid Credit Terms

All credits are prepaid and valid indefinitely. Unused credit does not expire, whether it is base credit or bonus credit. You can top up with a minimum of $10 using crypto (USDT or USDC). New accounts receive $0.50 in trial credit valid for 7 days, requiring no credit card or phone number. You can add funds at any time, and the bonus tier applies to each individual top-up. This pay-as-you-go model is ideal for pipelines with variable traffic patterns, from sporadic transcription jobs to steady-state captioning.

Questions and answers

How is the bonus credit calculated?

Bonuses are applied to the total amount of each individual top-up transaction. If you top up $50, you get a 5% bonus ($2.50). If you top up $100, you get a 10% bonus ($10). The bonus is added to your balance immediately.

Does my prepaid credit expire?

No. Neither base credit nor bonus credit expires. You can top up today and use the credits months or years later. There are no monthly fees or subscription renewals to manage.

What happens if my API key runs out of credit?

Your API key will return a 402 Payment Required error when your balance reaches zero. You can top up at any time to restore service. Your old key remains valid until you regenerate it.

Can I use bonus credits for any request?

Yes. Bonus credits are fungible with base credit. They can be used for input tokens, output tokens, streaming responses, or tool calling. There are no restrictions on how bonus credits are spent.
