Terms of Service

For the LLM inference API at openrouter-api.aliru.ai. Version of 1 September 2026.

1. Provider and scope

These terms govern the use of the LLM inference API operated by Aliru GmbH, Julius-Hatry-Straße 1, 68163 Mannheim, Germany (the "Provider"). They apply to any party accessing the API directly or through an intermediary platform (the "Customer"). Where access is brokered by a third party, that party's own terms additionally apply to the relationship between the Customer and that party.

2. Service

The Provider operates open-weight language models on its own infrastructure and makes them available through an OpenAI-compatible HTTP interface. The models offered, their context lengths, prices and capacity limits are published in the model catalog at /openrouter/models, which forms part of these terms.

The models are third-party open-source models used under their respective licences (Apache-2.0). They are served unmodified. The Provider does not warrant that model output is accurate, complete, current or fit for a particular purpose. Output is generated probabilistically and must be reviewed before being relied upon.

3. Availability

The Provider warrants an availability of at least 95 % per calendar month.

Availability is measured as the ratio of successfully answered requests to total requests received per calendar month, determined on the basis of the Provider's server-side records. The following are not counted as unavailability:

• scheduled maintenance, announced at least 24 hours in advance and limited to four hours per calendar month;
• requests rejected with HTTP status 429 due to capacity limits (see below);
• requests rejected as invalid, unauthenticated or exceeding the model's context length;
• faults in networks, systems or software not operated by the Provider, including the Customer's own connectivity and that of any intermediary platform;
• force majeure and other events outside the Provider's sphere of control.

If availability falls below 95 % in a calendar month, the Customer is entitled to a credit of 10 % of the fees incurred in that month, and of 25 % where availability falls below 90 %. The credit is granted upon request within 30 days of the end of the month concerned and is the sole remedy for a failure to meet the availability target. Claims for damages remain governed by clause 7.

Capacity is finite. Requests exceeding the published limits are rejected with HTTP status 429 and a Retry-After header. Rejected requests are not charged.

4. Acceptable use

The Customer shall not use the service to:

• generate or distribute content that is unlawful under German or applicable law;
• infringe third-party rights, in particular copyright, trademark or personality rights;
• generate content depicting the sexual abuse of minors, or content inciting violence or hatred;
• impersonate natural or legal persons, or create deceptive material presented as genuine;
• attempt to extract, reconstruct or reverse-engineer model weights;
• circumvent rate limits or authentication, or impair the availability of the service.

The Customer is responsible for the content submitted and for compliance with applicable law, including data protection law where personal data is contained in requests.

The Provider may suspend access without prior notice where there is concrete evidence of a material breach of this clause or where required to protect the integrity of the service.

5. Fees and billing

Fees are calculated on the basis of tokens processed, at the prices published in the model catalog. Token counts are returned with each response and form the basis of billing. Invoicing is monthly in arrears. All prices are net of statutory value added tax.

Prices may be adjusted with 30 days' notice. Continued use after the notice period constitutes acceptance.

6. Data protection

Processing of personal data is governed by the Privacy Policy. In summary: prompt and completion content is processed in memory only and is not stored, no training is performed on customer data, and processing takes place exclusively in Germany. Where the Customer transmits personal data, the parties shall conclude a data processing agreement pursuant to Art. 28 GDPR.

7. Liability

The Provider is liable without limitation for intent and gross negligence, for injury to life, body or health, and under the German Product Liability Act. In cases of slight negligence, the Provider is liable only for breach of a material contractual obligation, and such liability is limited to the foreseeable damage typical for this type of contract. Any further liability is excluded.

The Provider is not liable for decisions taken on the basis of model output, nor for consequential damage arising from reliance on such output without review.

8. Term and termination

The contract runs for an indefinite term and may be terminated by either party with 30 days' notice to the end of a calendar month. The right to terminate for cause remains unaffected. Termination shall be in text form.

9. Changes to these terms

The Provider may amend these terms with 30 days' notice where necessary to reflect changes in the service, the legal framework or case law. The version published here at the time of use applies.

10. Governing law and jurisdiction

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. Where the Customer is a merchant, a legal entity under public law or a special fund under public law, the place of jurisdiction is Mannheim, Germany.

11. Severability

Should any provision of these terms be or become invalid, the validity of the remaining provisions shall not be affected.
