Terms of Service
1. Who we are
"Zur-lix", "we", "us", or "our" refers to the operator of the Zur-lix service, reachable at [email protected]. "Customer", "you", or "your" refers to the individual or entity accessing the Service on behalf of themselves or an organization.
2. The Service
Zur-lix provides a managed proxy and gateway for third-party large language model APIs (including OpenAI and Anthropic). The Service includes prompt compression, rate limiting, per-key quotas, spend caps, metered usage aggregation, and consolidated billing ("the Service").
The Service does not provide the underlying model inference itself; model outputs originate from the third-party providers you direct your requests to. You remain subject to those providers' terms for the content of your requests and responses.
3. Eligibility
The Service is currently offered only to United States persons located in the United States. By accessing the Service, you represent and warrant that:
- You are at least 18 years old and, if accepting on behalf of an organization, authorized to bind that organization.
- You are a United States citizen, a lawful permanent resident of the United States, or a person lawfully residing in the United States; or an entity organized under the laws of a State of the United States with its principal place of business in the United States.
- You are physically located in the United States.
- You are not a Sanctioned Party (as defined below), and you will not access the Service from a Sanctioned Country (as defined below).
"Sanctioned Party" means any person or entity listed on the U.S. Department of the Treasury Office of Foreign Assets Control ("OFAC") Specially Designated Nationals List, the U.S. Department of Commerce Denied Persons List or Entity List, the U.S. Department of State Debarred List, or any equivalent restricted-party list maintained by the U.S. government — or any party 50% or more owned, individually or in aggregate, by any such listed party.
"Sanctioned Country" means any country or region subject to comprehensive U.S. sanctions, currently including Cuba, Iran, North Korea, Syria, the Crimea region of Ukraine, the so-called Donetsk People's Republic, and the so-called Luhansk People's Republic. This list may change as U.S. sanctions law evolves; the version of these Terms in effect at the time of your access governs.
We may verify your eligibility at any time, including by checking the billing address you provide against the requirements above. Accounts opened in violation of this Section may be terminated without refund. Misrepresentation of eligibility is a material breach of these Terms.
4. Accounts, keys, and security
You are responsible for: (a) keeping your API keys confidential, (b) all activity performed under your keys, (c) ensuring your use complies with applicable law and the terms of any upstream provider you access through us. You must notify us promptly at [email protected] if you suspect a key has been compromised.
5. Acceptable use
You agree not to use the Service to:
- Violate applicable law, third-party rights, or the terms of upstream model providers.
- Generate content depicting the sexual exploitation of minors, incite violence, or facilitate the creation of weapons capable of mass harm.
- Attempt to circumvent rate limits, spend caps, quotas, or authentication controls.
- Reverse engineer, probe, or attack the Service or its infrastructure.
- Resell the Service without a written reseller agreement.
We may suspend or terminate access for material violations, with or without notice depending on severity.
6. Sanctions and export control
You agree to comply with all applicable U.S. sanctions, embargo, anti-money-laundering, and export-control laws, including the regulations administered by OFAC, the U.S. Department of Commerce Bureau of Industry and Security, and the U.S. Department of State Directorate of Defense Trade Controls.
You will not export, re-export, transfer, or make available the Service, any output of the Service, or any technology supplied to you in connection with the Service: (a) to any Sanctioned Party, (b) to or from any Sanctioned Country, or (c) for any prohibited end-use under the U.S. Export Administration Regulations (15 C.F.R. Parts 730–774) or the International Traffic in Arms Regulations (22 C.F.R. Parts 120–130).
You acknowledge that the Service may incorporate or rely on encryption technology subject to U.S. export controls. You are solely responsible for confirming the applicability of, and complying with, any export-control or import-control requirements that arise from your use of the Service.
7. Fees and metered billing
The Service is priced as a monthly subscription plus metered usage. Your selected plan's base fee is billed in advance each period; metered usage is aggregated and billed in arrears through Stripe. Usage is measured in micro-dollars of upstream model cost and multiplied by the margin disclosed on your plan (currently 1.30 unless otherwise agreed).
Plans, margins, and limits may change on 30 days' notice delivered by email or in-product banner. Changes take effect at the start of the next billing period.
Spend caps, when configured, are enforced best-effort. Requests that would exceed a cap are refused. You remain responsible for usage that lands within your configured cap.
8. Taxes
Fees are exclusive of taxes. You are responsible for any sales, use, VAT, GST, or similar taxes applicable to your purchase, except for taxes based on our net income.
9. Term and termination
Either party may terminate the subscription at any time through the customer portal. Termination takes effect at the close of the current billing period; metered charges accrued through that point remain payable. Upon termination we may delete your account and associated metering records after 90 days.
We may suspend or terminate your access immediately, without refund, if we determine that you have breached Section 3 (Eligibility), Section 5 (Acceptable Use), or Section 6 (Sanctions and Export Control).
10. Data and confidentiality
Our handling of prompts, completions, metering records, and personal data is governed by our Privacy Policy, which is incorporated by reference. We will not use your prompt or completion content to train models.
Each party will protect the other's confidential information with at least the same care it uses for its own, and for no less than reasonable care.
11. Service availability
We aim for high availability but do not promise uninterrupted service. The Service is provided "as is" to the extent permitted by law. We may pause or throttle traffic during incidents or maintenance windows and will post status updates at a URL designated in your account.
12. Intellectual property
You retain all rights in the prompts, content, and data you send through the Service. We retain all rights in the Service itself, our software, and our documentation. No rights are granted by implication.
13. Disclaimers and limitation of liability
To the maximum extent permitted by law, the Service is provided without warranty of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. Model outputs may be inaccurate, offensive, or unsuitable for production use without validation.
Neither party is liable for indirect, incidental, special, consequential, or punitive damages, or for loss of profits, revenue, or data, even if advised of the possibility. Our aggregate liability arising out of or related to the Service is capped at the amounts paid by you to us in the 12 months preceding the event giving rise to the claim.
14. Indemnity
You agree to indemnify and hold us harmless from claims arising out of your breach of these Terms, your violation of law (including U.S. sanctions and export-control law), or your infringement of a third party's rights through your use of the Service.
15. Changes to these Terms
We may update these Terms. Material changes will be notified by email to the account owner at least 14 days before they take effect. Continued use after the effective date constitutes acceptance.
16. Governing law and disputes
These Terms are governed by the laws of the State of Delaware, without regard to its conflict-of-laws principles. The United Nations Convention on Contracts for the International Sale of Goods does not apply.
Each party consents to the exclusive jurisdiction of the state and federal courts located in New Castle County, Delaware for any dispute arising out of or relating to these Terms or the Service, except that either party may seek injunctive or other equitable relief in any court of competent jurisdiction to protect its intellectual property or confidential information. You waive any objection to venue or personal jurisdiction in those courts.
