One key.
Open-weight AI models — DeepSeek, Qwen, Kimi, Llama and more — through a single OpenAI-compatible key. One balance, pay per token.
Every model is one string away
Keep your code. Change the model name — the key, the balance and the bill stay the same.

Explain what a reverse proxy does in one sentence.
A reverse proxy sits in front of your servers, takes requests from clients and forwards each one to the right backend — so clients only ever talk to one address.

Pay only for tokens
No subscriptions. Top up your balance in your currency, and each request is charged at the model's fixed price. Unused balance can be refunded on request.
- Price per 1M tokens and per typical answer
- A receipt for every top-up
- An email when your balance runs low
Questions people actually ask
So what am I actually paying for?
For tokens — the text a model reads and writes. You top up once, and every request is deducted at the price listed next to the model. No subscription, no minimum monthly spend, no surprise overage.
Will I have to rewrite my code?
No. If your app talks to the OpenAI API, change two lines — base_url and the key — and you're done. The same goes for Cursor, Cline, n8n, LangChain and anything else that accepts a custom endpoint.
Which countries and payment methods do you support?
We work with customers worldwide. You can pay by card in eight currencies, and companies can ask for an invoice. Your balance is kept in USD, so the price of a request doesn't jump around with exchange rates.
What if a model goes down on the provider's side?
Most models have a backup source, so the request is quietly retried there. If there's no healthy source left, you get a clear error and we don't charge you for it.
Do you read or keep my prompts?
No. By default we store only metadata: which model, how many tokens, what it cost. Your prompts go to the model provider to generate the answer, and that's it. You can turn on full logging for debugging if you want it.
Can I get my money back?
Yes. Unused balance is refunded on request. If you're in the EU or UK, you also have a 14-day right of withdrawal — the details are in our refund policy.
How do I try it before paying?
Sign up and you get free credit straight away — enough for a few hundred answers from a budget model. No card needed.
Why not just go to OpenAI or Anthropic directly?
You can. We're useful when you want several vendors without several accounts, cards and invoices; when you need a budget per key; or when you want automatic fallback if one provider is having a bad day.
