Terms of Use
These terms govern your use of the FifeRouter API and this website. By creating an account or sending a request with an API key, you agree to them.
1. The service
FifeRouter is an OpenAI-compatible API gateway that classifies each
request by concept and routes it to a model according to a published
policy. We decide which model serves a request. Which models are
eligible, and the constraints that gate them, are published on our
models and concepts
pages, and any individual decision can be inspected without being
served through /v1/explain.
2. Accounts
You need an account to obtain an API key. You must give an accurate email address, keep your password and keys confidential, and tell us promptly at security@fiferouter.com if you believe a credential has been exposed. You are responsible for all usage authenticated by your keys, including usage by anyone you have given them to.
A key is shown once when it is created and stored only as a hash. We cannot recover it for you. If it is lost, revoke it and create another.
3. Credit, billing and spend
The service is prepaid. You buy credit through Stripe, and your balance is drawn down as you use the API.
- Credit is added when Stripe confirms the payment — not when your browser returns from checkout. There is normally no perceptible gap, but the two are different events and only the first moves your balance.
- You are charged per model attempt, at the rates published on the pricing page, computed from the token counts the provider reports. Where a request falls back to a second model, both attempts are billable, because both were made.
- Metering runs shortly after the request, not during it. A consequence we accept and state plainly: when your balance crosses zero, requests already in flight will complete, so it is possible to end slightly below zero. We do not treat that as a debt.
-
An exhausted balance stops service, with a
402, before the request costs anything. - Credit does not expire and is not transferable between accounts.
4. Refunds
Unused credit is refundable on request for 12 months from purchase. Write to billing@fiferouter.com from the account's email address. We refund to the original payment method, and the corresponding amount of credit is removed from your balance at the same time — a refund reverses the purchase, it does not duplicate it.
Credit you have already spent is not refundable, except where we have billed you in error. If you think we have, tell us: the ledger and the decision records behind it are visible to you in your dashboard, and we will correct any entry we cannot justify.
Where a refund would leave your balance negative — because you spent credit before asking for it back — we refund only the unspent portion.
5. Acceptable use
You may not use the service to:
- break the law, or help anyone else to;
- infringe someone's intellectual property, privacy or other rights;
- generate material that sexually exploits children, incites violence, or harasses a person;
- attempt to breach, overload or circumvent the service's security or rate limits, or to access another account's data;
- resell raw access in a way that hides that we are the provider, or that would put us in breach of an upstream provider's terms.
Requests you send are also subject to the terms of whichever model provider serves them. We may suspend an account that breaches this section, and will tell you why unless the law prevents us.
6. Your content
You keep all rights in what you send and in what the models return to you. We claim no ownership and do not use your prompts or responses to train anything — we do not retain them at all. See the privacy policy for what we do retain.
7. Availability
We do not currently offer a contractual uptime guarantee. We publish our own monitoring and will be straightforward about outages. We may change, suspend or withdraw parts of the service; where a change would materially reduce what you have already paid for, we will refund unused credit.
8. Warranties and liability
The service is provided "as is". Model outputs are probabilistic and may be wrong, and routing decisions are made by policy rather than by judgement of your particular case. Do not rely on an output for a consequential decision without checking it.
To the extent the law permits, we exclude implied warranties, and our total liability arising out of these terms is limited to the greater of the amount you paid us in the 12 months before the claim, or £100. We are not liable for indirect or consequential loss, lost profits, or lost or corrupted data. Nothing here limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be limited.
9. Ending it
You may close your account at any time; ask us and we will refund unused credit under section 4. We may suspend or close an account for a breach of these terms, for non-payment, or if required by law.
10. Changes to these terms
We will update the date above and, for material changes, email account holders at least 14 days before they take effect. Continuing to use the service after that is acceptance. Every version is in the public repository.
11. Governing law
These terms are governed by the laws of England and Wales, and the courts of England and Wales have exclusive jurisdiction. If you are a consumer, this does not deprive you of protections you have under the law of the country you live in.
