Long-context document analysis
Processing a 30,000-token document (input) and generating a 2,000-token summary (output). Cost: (30,000 / 1,000,000 * $0.15) + (2,000 / 1,000,000 * $0.50) = $0.0045 + $0.001 = $0.0055.
AI Gateway: Token pricing
Pay only for the tokens you process with our prepaid, non-expiring credits. Our transparent token rates ensure you never overpay for unused capacity or hidden subscription fees.

Pay-As-You-Go: No Subscriptions, No Expiry
Our pricing model is designed for developers who prefer direct control over their AI costs. You top up with prepaid credits, and those credits never expire. There are no monthly subscription fees, no minimum commitments, and no hidden charges for idle time. This approach eliminates the waste associated with traditional subscription tiers where you pay for capacity you might not use. Since the credit balance is fixed until you add more, your spending is inherently predictable. You only pay for the actual tokens processed, making it easy to budget for long-term projects or sporadic usage spikes without financial risk.
Token Rates: Input vs. Output Costs
We charge differently for input and output tokens to reflect the computational cost of processing context versus generating responses. Input tokens are priced at $0.15 per 1 million tokens, while output tokens cost $0.50 per 1 million tokens. This ratio reflects the higher compute demand for generation. For example, a 10,000-token input and a 1,000-token output costs only $0.0035. These rates apply to our uncensored 100k context model. The pricing is consistent across all requests, whether streaming or non-streaming. This transparency allows you to accurately estimate costs for your specific workload before you begin development.
Top-Up Bonuses: Maximize Your Credit
To reward heavier usage, we offer bonus credits on larger top-ups. When you add $50 or more to your account, you receive a 5% bonus on your credit balance. For top-ups of $100 or more, the bonus increases to 10%. These bonuses are applied instantly and last indefinitely, just like your base credits. This means you get more compute power for your money without any additional complexity. The bonus credits are deducted proportionally with your base credits during usage. This structure favors developers who run consistent workloads or need to scale up their AI integration without worrying about sudden cost spikes.

Questions and answers
Do my prepaid credits expire?
No, your prepaid credits never expire. Once you top up your account, the balance remains available for use indefinitely. There is no deadline or usage requirement to keep your credits valid.
How does the free trial work?
New users get $0.50 of trial credit, one per person, valid for 7 days. Claim this credit with one click on your API key page. No credit card is required to start. This allows you to test the API with real requests before committing to a top-up.
Can I use both bonus and base credits simultaneously?
Yes. When you make a request, both your base credits and bonus credits are used proportionally. You do not need to choose which balance to spend first; they are treated as a single pool.
What happens if I exceed my balance?
Requests will fail if your balance is insufficient to cover the cost of the tokens. Since there are no subscriptions, you will not incur debt. You simply need to top up your account to continue making requests.
