Prepaid credit. Published rates.
You buy credit once and it is spent on tokens at the provider's own published rates. There is no subscription, no seat and no minimum.
How the multiplier works: your credit is spent against the per-token rates below. A 2× multiplier means a $5.00 payment covers $10.00 of metered usage — no rate changes, no hidden spread.

What each token costs.
USD per 1 million tokens, read across as input / cached input / output. Cached input is billed only for prompt tokens the provider served from cache.

How the money actually moves.
How billing works
429. We do not
auto-charge a card on file.Included with every plan
- Full context windows and streaming
- Tool / function calling and JSON mode
- Own keys scoped to your models
- Prompt caching billed at the cached rate
- Unused credit carries, it does not expire on a cycle
Billing, limits, and what is not charged.
Is there a monthly fee?
No. Credit is prepaid and spent as you use it. If you stop using the API you simply stop spending — there is nothing to cancel.
What happens if I go over?
Nothing breaks and no card is charged. Once the balance is
spent, the API returns 429 with a budget message until you add
credit. Your keys and configuration stay exactly as they are.
Why is cached input so much cheaper?
Upstream providers charge a reduced rate for prompt tokens they can reuse from a previous request. We pass that straight through — on DeepSeek v4.1 Flash it is 50× cheaper than standard input, which matters a lot for agent loops and stable system prompts.
Do you charge a markup on top of the rates?
The per-token rates are the providers' published prices. The discount you receive is the credit multiplier on your payment, shown above — not a quiet spread added to every token.
Are failed requests billed?
No. A request that errors — a rejected model, an invalid key, an upstream failure — is not billed. Only requests that return a completion are metered, and the usage log shows exactly which ones were.
Is there a minimum spend or lock-in?
No. There is no minimum, no contract and no monthly fee. You buy credit and spend it at your own pace; if you stop using the API you simply stop spending.
Are streaming responses billed differently?
No. Streaming and non-streaming requests are metered the same way, from the same token counts, at the same rates.
Do I need to talk to sales to get started?
No. There is no sales conversation, no approval step and no waitlist. Create an account, add credit and call the API.
Can I get an invoice?
Yes. Every purchase produces an invoice in your console, and administrator-marked payments are recorded the same way as card payments.
What about limits?
Traffic is shared across a pool of upstream capacity, so very high burst rates can be rate-limited at peak. Steady production traffic is unaffected. See the limits section of the docs.
