Terms of Service

CentRouter (“we”) is a prepaid AI gateway. You buy a Balance in USD, create API Keys, and call the models in the Catalog through one API that speaks the OpenAI and Anthropic formats.

There is no subscription and no monthly minimum. Your Balance is charged only for the Requests you make.

CentRouter is not affiliated with, endorsed by or sponsored by Anthropic, OpenAI, Google or any other company that makes the models in the Catalog. Model and company names identify the models only.

These terms apply from the moment you create an account. Creating an account accepts them, and we record the date and the version you accepted. If you do not agree with them, do not use the service.

You need an account with an email address that you verify. Keep your sign-in details to yourself. You can add two-factor authentication in Settings.

If your account has a password, you can change its email address in Settings. The change takes effect only after you open the link we send to the new address.

• A new API Key is shown in full when you create it. After that we keep only its hash and a short prefix, so a lost key cannot be shown again: revoke it and create a new one.
• You can have up to 10 active API Keys.
• A Spend Limit caps what one API Key may charge per day, per month or in total. You can also restrict a key to a list of models.
• If a key leaks, revoke it on the API Keys page. The gateway stops accepting it within 15 seconds.

You are responsible for every Request made with your API Keys, including Requests made by someone else who got hold of a key.

Your Balance is prepaid and kept in USD. It grows when a Payment Provider confirms an Order you paid, when you redeem a Voucher, or when we credit it ourselves, for example with a manual top-up or a correction.

• Each Request is charged for the Tokens the model reports (input, cache read, cache write and output), each multiplied by its Sell Price per 1M Tokens. If a model does not report its usage, the Tokens are estimated and the Request is marked “estimated” in Activity.
• If we gave your account a group discount, your Requests are charged the discounted Sell Prices.
• While a Request runs, we hold its largest possible cost and release the unused part when it ends. A Balance never goes below zero.
• A Request that is rejected, or that no model source could answer, costs nothing. A response that stops partway is charged for the Tokens already delivered.
• Sell Prices are listed on the Pricing page and can change. A new price applies to new Requests only: each Request stores the prices it was charged at.
• Rupiah amounts shown beside USD amounts are estimates at the current Exchange Rate. An Order paid in Rupiah records the Exchange Rate it used, and the amount on that Order is the amount you pay.
• An Order is added to your Balance once. If the amount paid is lower than the Order’s amount, the payment is checked by hand before it is credited.

A Balance has no expiry date. A Voucher code can carry a date by which it must be redeemed; once redeemed, its amount is Balance like any other.

Every change to your Balance is recorded in the Ledger on the Balance page.

A Balance is not refundable. It cannot be withdrawn as money and cannot be transferred to another account.

We correct two payment errors:

• A top-up that was charged twice.
• A payment that was taken but never reached your Balance.

To report one, write to support@centrouter.com with the Order ID from the Balance page.

Use the service only for lawful purposes. You may not use it from a country or region under comprehensive sanctions, or if you are on a government list of restricted parties.

You must not:

• try to get around the service’s limits or security, including rate limits, Spend Limits and a block on an account;
• disrupt the service or other users, for example with malware or denial-of-service attacks, or try to reach systems or accounts that are not yours;
• create accounts with false or stolen identities;
• scrape or extract data from the service other than through its API, within its limits;
• run jailbreaking, prompt-injection or other adversarial testing against a model without the written approval of the company that makes it and of us;
• use the service to infringe the privacy, security or intellectual property rights of anyone.

Each API Key has rate limits: by default 60 Requests per minute and 5 running at once.

What you send to a model must also follow the usage policies of the company that makes that model. Those policies apply to your Requests in addition to these terms.

You may build a product on top of the service and let your own customers use it, but only if your customers agree to terms at least as strict as these, you stay responsible for their use and their payments, you do not present your product as provided by or affiliated with any model maker, and you do not switch off or misrepresent any of the service’s limits.

Models can be added to the Catalog, removed from it, or become unavailable. The Pricing page lists the models you can call now.

The Status page shows how each model has been answering.

We do not guarantee that the service or any model will be available without interruption.

We can block an account, for example when it breaks these terms.

While an account is blocked, the gateway rejects its API Keys, and the account cannot add Balance, redeem Vouchers or create API Keys. You can still sign in and see your Balance, Activity, Orders and Ledger.

You can stop using the service at any time. Your Balance is charged only for Requests, so nothing is charged while you make none.

You can close your account at any time in Settings. We can also close an account, for example when it breaks these terms.

• Closing is immediate and cannot be undone.
• Your API Keys are revoked, and the gateway stops accepting them within 15 seconds. Your sign-in is removed and your unpaid Orders expire.
• The Balance that remains when the account closes is removed and is lost. It is not paid out and cannot be moved to another account. The confirmation shows the amount before you close.
• A payment that arrives for an Order of a closed account is not added to a Balance. It is held and checked by hand.

The same email address can sign up again. That is a new account, and nothing from the closed one carries over.

The Privacy Policy lists what closing deletes and what is kept.

We may change these terms. The date at the top of this page shows when they last changed.

If you keep using the service after a change, the changed terms apply to you.
