AVELIN Terms of Service

Last modified: August 6, 2026

Introduction

These terms of service ("Terms") provide the rules that govern access to and use of the AVELIN platform by you ("you" or "your"): your personal account and our web console at platform.avelin.ai, our API at api.avelin.ai, and the related services we provide (collectively, the "Services"). The Services are provided by AVELIN AI, Inc., a Delaware corporation ("AVELIN", "Company", "we", "our", "us"). In addition to api.avelin.ai, we may provide regional or cluster-specific API endpoints under our domains; any such endpoints are provided in your personal account and form part of the Services and of the "API" as used in these Terms. Use of our public marketing website avelin.ai is governed separately by our Website Terms of Use; other AVELIN products (such as AVELIN App and AVELIN MCP) have their own terms. Any breach of these Terms may result in suspension or termination of your access to the Services.
AVELIN in Few Words (TL;DR):

a. We provide scalable, production-ready API access to AVELIN's proprietary AI models (trained routing over specialized open-weight expert models) through an OpenAI- and Anthropic-compatible API.

b. Each open-weight model incorporated in our Services is subject to its own license rights, terms, and conditions, to which you are also subject.

c. Inputs you provide to our API and the outputs it generates are your private data. We will not store or sell this data, and we will not train on it unless you explicitly consent by enabling the optional model-improvement setting (off by default; de-identified embeddings only), via your account settings or a dedicated consent dialog. We might sometimes retain, for a limited period not exceeding 30 days, inputs and outputs of API calls for debugging or security purposes, never for training. Our Data Policy describes how we process and treat data supplied to or returned by our Services.

d. Billing is usage-based at the per-token prices (including any cached-input rates) published at https://api.avelin.ai/public/models.json.

e. You may use the Services for any legal commercial purpose unless specifically prohibited below.
By accessing or using the Services, you represent that you are at least 18 years old, that you have read and understood these Terms, and that you agree to be bound by them. If you use the Services on behalf of a company or other organization, you represent and warrant that you have the legal authority to bind it. If your organization has a separately signed agreement with AVELIN (such as a cloud service agreement or data processing agreement), that agreement controls to the extent of any conflict with these Terms. If you do not agree to these Terms, do not access or use the Services.
We reserve the right to change these Terms. When we do, we will update this page and revise the "Last modified" date above, and we may notify you by email or through your account of material changes. Changes take effect upon posting; your continued use of the Services after changes are posted constitutes your acceptance of the modified Terms. If a change is not acceptable to you, your sole recourse is to stop using the Services.
Please note: these Terms provide that disputes between you and AVELIN will be resolved by binding, individual arbitration, and that you waive the right to a jury trial and to participate in class actions, as described in the Legal Disputes and Arbitration section below.

Services

To access and use our Services, you must create an account ("Account"). Our pricing varies by model and is published at https://api.avelin.ai/public/models.json; usage is billed at the published prices in effect at the time of use. Depending on your plan, we will charge the payment method on file for accrued usage at the end of each billing period, or draw down prepaid credits as you use the Services, and you consent to such charges. Fees are exclusive of taxes, which are your responsibility. Except where we cancel a paid order or where required by law, fees and prepaid credits are non-refundable. We reserve the right to modify published prices and payment terms prospectively; changes do not affect usage that has already occurred.
We may change or discontinue any of the Services from time to time. Where we discontinue material functionality that we make generally available and that you are using, we will give you reasonable prior notice, except where discontinuation is necessary to address an emergency or risk of harm, respond to claims or loss of third-party rights, or comply with law; in such cases we will give as much notice as is reasonably practicable.
You are entirely responsible for maintaining the confidentiality of your Account information, including passwords, API keys, and other authentication credentials, and for all activity that occurs under your Account. Notify us immediately at hello@avelin.ai of any unauthorized use of your Account or any other breach of security. You may not use anyone else's account or credentials. Registration is void where prohibited or where the registrant lacks eligibility.
The Services are engineered for high availability but are provided without a guaranteed service level unless agreed in a separately signed agreement. Support is available at hello@avelin.ai.
We encourage you to review our Privacy Policy and Data Policy.

Required Conduct

While using the Services, you will comply with all applicable laws, rules, and regulations, with our published documentation, and with the rate limits applicable to your API keys. Your use of the Services is conditioned on your compliance with the rules of conduct in these Terms; failure to comply may result in suspension or termination of your access.

Prohibited Conduct

While using the Services, you shall not, and shall not permit any user to:

Decompile, disassemble, or reverse engineer the Services, or otherwise attempt to discover the source code, underlying structure, or algorithms of the Services (other than their open-source elements), including attempting to extract, reconstruct, or derive the weights or routing logic of our models, or using outputs to train or distill models that compete with the Services.
Remove any copyright or other proprietary markings from materials or software in the Services.
Breach, disable, interfere with, or circumvent any security, authentication, metering, or rate-limiting measures of the Services, or otherwise overload, flood, or spam any part of the Services.
Probe, scan, or test the vulnerability of the Services or any connected network without our prior written authorization.
Store or transmit any malware, backdoors, viruses, or other harmful code.
Resell or redistribute the Services except through distribution partnerships authorized by AVELIN in writing.
Use the Services in high-risk activities where failure could reasonably be expected to lead to death, bodily injury, or environmental damage (including autonomous vehicles, medical life-support, emergency response, nuclear facilities, or air traffic control) without qualified human oversight.
Attempt to defraud us or any other person, or use any account you are not authorized to use.
Impersonate any individual or entity, or misrepresent your affiliation with any person or entity, including AVELIN.
Use the Services in any manner or for any purpose that is illegal, fraudulent, or deceptive, that infringes the rights of AVELIN or others, or that would give rise to civil liability, or to solicit, encourage, or promote any such activity.
Use the Services in any manner, including a denial-of-service attack, that could interfere with, damage, disable, overburden, or impair the functioning of the Services or any connected systems or networks.

Suspension or Termination of Access

Notwithstanding any provision to the contrary in these Terms, we may, in our sole discretion and with or without prior notice, suspend or terminate your Account or your access to any or all of the Services for violation of these Terms, unlawful use, non-payment, or use that materially and negatively impacts the Services or others; where practicable, we will try to inform you before suspending your Account. We shall not be liable to you or any third party for any such suspension or termination. Provisions of these Terms which by their nature should survive termination shall survive.

Termination

You may terminate your Account for any reason by providing us notice or by using the account deletion functionality, once you have paid all outstanding fees, including usage accrued through the termination date. Upon termination, your access to the Services will cease and you remain responsible for all fees incurred through that date. For fraud-prevention purposes, we may retain your Account data for thirty (30) days after closure, after which we will delete it, subject to legal retention requirements (see the Privacy Policy).

Your Submissions and AI Outputs

In using the Services, you may submit data, content, materials, or requests into the models ("Submissions"). You retain all intellectual property rights in your Submissions, which remain your private data. By submitting them, you grant us (or warrant that the rights owner has granted us) the limited right to process the Submissions through the Services and for the bounded debugging and security purposes described in our Data Policy. We do not own your Submissions.
As between you and AVELIN, and to the extent permitted by law, you own the outputs the Services generate for you, and we assign to you any rights we may have in them.
We will not store or sell your Submissions or outputs, and we will not train on them. We do not use them to train, fine-tune, or improve any model, including derived artifacts such as embeddings, unless you explicitly consent by enabling the optional model-improvement setting, which is off by default, may be enabled in your account settings or through a dedicated consent dialog, and may be disabled at any time. In that case, we may derive de-identified vector representations (embeddings) from your Submissions and use those vectors to train, evaluate, and improve our models, as described in our Data Policy. Traffic from distribution partners (including OpenRouter) is never enrolled in this setting. In the normal operation of the Services, content is processed in memory and transient buffers are deleted within 5 minutes of request completion; we might retain a small portion of Submissions and outputs, for a limited period not exceeding 30 days, for debugging or security purposes, as described in our Data Policy.
For each Submission, you represent and warrant that you have all rights necessary to grant the license above, and that the Submission and its processing through the Services do not violate any privacy, publicity, contractual, intellectual property, or other rights of any person or entity or any applicable law. You are responsible for, and will pay, any royalties, fees, or damages owed to any person by reason of your Submissions. We may terminate access to the Services for anyone we suspect of infringing intellectual property rights.
AI-generated outputs are produced probabilistically and may be incorrect, incomplete, or unsuitable for your purpose. They are not professional advice and are not a substitute for human oversight; you must evaluate outputs for your use case before relying on them.

Model Licenses

The Services incorporate open-weight AI models that are subject to their own license rights, terms, and conditions. Where an applicable model license imposes obligations on end users, you agree to comply with those obligations. The open-weight components used by the Services and their license terms are identified in our documentation.

Intellectual Property

With the exception of open-source elements, your Submissions, and outputs generated for you, we own all rights, title, and interest (including intellectual property rights) in and to the Services, including our proprietary models and model adaptations, routing and orchestration technology, software, documentation, trademarks, logos, and the design and arrangement of the Services ("AVELIN IP"). We grant you a non-exclusive, non-transferable, revocable, limited license to access and use AVELIN IP solely to use the Services. This license terminates automatically if you breach these Terms or your Account is deleted.
If you provide feedback, suggestions, or recommendations about the Services, you grant us a worldwide, royalty-free, irrevocable, perpetual license to use and incorporate such feedback without restriction or obligation, and you acquire no rights in the Services by providing it.
DMCA. If you believe in good faith that material available on the Services infringes your copyright, you (or your agent) may send us a notice under the Digital Millennium Copyright Act requesting removal or blocking; if you believe a notice was wrongly filed against you, you may send a counter-notice. Notices and counter-notices must meet the then-current statutory requirements of the DMCA (see 17 U.S.C. § 512) and should be sent to hello@avelin.ai. Knowing misrepresentations in a notice may make you liable for resulting damages, including costs and attorneys' fees. We may limit access to the Services or terminate the accounts of infringers.

Links and Third-Party Content

From time to time we may host or link to products, services, websites, or other content of third parties, including open-weight models ("Third-Party Content"). Third-Party Content is provided solely as a convenience; its inclusion does not imply our affiliation, endorsement, or adoption. We make no representations and accept no responsibility for Third-Party Content, and your use of it is at your own risk and subject to the third party's own terms and policies, which you should review.

Warranties and Liability

Disclaimer of Warranties. TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICES AND ANY CONTENT, MATERIALS, OR SERVICES PROVIDED BY US OR OUR SUPPLIERS ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OR GUARANTEES OF ANY KIND. WE AND OUR SUPPLIERS EXPRESSLY DISCLAIM ALL REPRESENTATIONS AND WARRANTIES, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND ANY WARRANTY REGARDING THE QUALITY, ACCURACY, TIMELINESS, COMPLETENESS, OR RELIABILITY OF THE SERVICES OR OF AI-GENERATED OUTPUTS. WE DO NOT GUARANTEE THAT THE SERVICES WILL BE UNINTERRUPTED, SECURE, ERROR-FREE, OR OPERATE AT ANY PARTICULAR SPEED, OR THAT DEFECTS WILL BE REMEDIED. WE MAY SUSPEND, WITHDRAW, DISCONTINUE, OR CHANGE ALL OR ANY PART OF THE SERVICES AT ANY TIME.
Exclusion of Liability. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL WE OR OUR SUPPLIERS BE LIABLE TO YOU OR ANY THIRD PARTY UNDER ANY THEORY OF LIABILITY FOR ANY INDIRECT, CONSEQUENTIAL, EXEMPLARY, INCIDENTAL, SPECIAL, OR PUNITIVE DAMAGES, OR ANY LOSSES RESULTING FROM BUSINESS INTERRUPTION, LOST PROFITS, LOSS OF BUSINESS OPPORTUNITY, GOODWILL, OR REPUTATION, ARISING FROM YOUR USE OF OR INABILITY TO USE THE SERVICES, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. WE AND OUR SUPPLIERS HAVE NO LIABILITY FOR CLAIMS ARISING FROM CONTENT THAT YOU PROVIDE TO US.
Limitation of Liability. NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THESE TERMS, OUR AND OUR SUPPLIERS' AGGREGATE LIABILITY FOR ANY LOSS OR DAMAGE ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE SERVICES AND THESE TERMS, WHETHER IN CONTRACT, TORT, OR OTHERWISE, SHALL NOT EXCEED THE TOTAL AMOUNT PAID BY YOU FOR THE SERVICES GIVING RISE TO SUCH LIABILITY IN THE TWELVE MONTHS PRECEDING THE FIRST INCIDENT OUT OF WHICH THE LIABILITY AROSE. IF NO FEES WERE PAID, OUR AND OUR SUPPLIERS' LIABILITY TO YOU IS LIMITED TO $1,000.
SOME JURISDICTIONS DO NOT PERMIT THE FOREGOING EXCLUSIONS; IN SUCH CASES, THE ABOVE EXCLUSIONS AND LIMITATIONS APPLY TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, AND NOTHING IN THESE TERMS LIMITS LIABILITY THAT CANNOT BE LIMITED BY LAW.

Indemnification

You agree to indemnify and hold harmless AVELIN and our suppliers, shareholders, partners, employees, contractors, agents, and affiliates from and against any third-party claims arising from: (1) your use of the Services; (2) any content you submit to the Services; (3) your conduct in connection with the Services; (4) your breach of these Terms or any agreement you enter into with us; and (5) your violation of any law or the rights of any third party in connection with the Services. You will not be required to indemnify us to the extent a claim results exclusively from our own negligent conduct.
Our rights to indemnification are conditioned on us giving you reasonable notice of the claim and reasonable cooperation at your request and expense. We may participate in the defense at our own expense. You shall not enter into any settlement that adversely affects our interests without our prior written approval, not to be unreasonably withheld. No delay in notice relieves you of your obligations except to the extent it materially impairs your defense.

Legal Disputes and Arbitration

Any dispute, claim, or controversy arising out of or relating to these Terms or the Services, including their breach, termination, enforcement, interpretation, or validity, and the scope or applicability of this agreement to arbitrate, shall be determined by binding arbitration in Wilmington, Delaware before one arbitrator, administered by JAMS pursuant to its Comprehensive Arbitration Rules and Procedures, including the Expedited Procedures. Judgment on the award may be entered in any court of competent jurisdiction. This clause does not preclude either party from seeking provisional remedies in aid of arbitration from a court of appropriate jurisdiction. The parties understand that, absent this provision, they would have the right to sue in court and have a jury trial, and that discovery may be more limited in arbitration.
You and we each agree that any arbitration shall be conducted in our respective individual capacities only, and not as a class action or other representative action, and each of us expressly waives the right to file a class action or seek relief on a class basis.
Notwithstanding the foregoing, either party may seek relief in a small claims court for disputes within the scope of that court's jurisdiction.

General

These Terms and the relationship between you and AVELIN are governed by the laws of the State of Delaware, without regard to its conflict-of-laws provisions; the United Nations Convention on Contracts for the International Sale of Goods does not apply. If any provision of these Terms is found invalid or unenforceable, the court or arbitrator should endeavor to give effect to the parties' intentions, and the remaining provisions remain in full force. A waiver is effective only in a written document; our failure to enforce any provision is not a waiver. You may not transfer, assign, or delegate your rights or duties under these Terms without our prior written consent, and any attempt without consent is void; we may freely assign our rights and duties, including in connection with a merger, acquisition, or sale of assets. These Terms bind and benefit the parties and their permitted successors and assigns. There are no third-party beneficiaries of these Terms. The parties are independent contractors; nothing in these Terms creates an agency or partnership. Nothing in these Terms obligates us to enter into any commercial transaction. The Services may be subject to export controls and sanctions laws, including those of the United States; you represent and warrant that you will not export or re-export the Services or related content in violation of these regulations and that you are not located in an embargoed region or designated on any restricted-party list. You acknowledge that your breach of these Terms may cause immediate and irreparable harm for which money damages are inadequate, and either party may seek provisional or injunctive relief in aid of arbitration in a court of appropriate jurisdiction, consistent with the Legal Disputes and Arbitration section, without limiting other remedies. We are not liable for delays, failures, or inadequate performance resulting from conditions outside our reasonable control, including natural disasters, network or utility failures, acts of terrorism or war, riots, labor strikes, or governmental acts.

Notices to Consumers

Where any consumer protection legislation in your jurisdiction applies and cannot be excluded, these Terms do not limit your rights and remedies under that legislation, and its mandatory provisions prevail in case of conflict.

New Jersey. If any provision of these Terms is held unenforceable, void, or inapplicable under New Jersey law, that provision does not apply to New Jersey consumers, but the remainder remains binding; nothing in these Terms limits rights available to New Jersey consumers under the Truth-in-Consumer Contract, Warranty and Notice Act.

California. Under California Civil Code Section 1789.3, California consumers may reach the Complaint Assistance Unit of the Division of Consumer Services of the California Department of Consumer Affairs by mail at 1625 North Market Blvd., Suite N 112, Sacramento, CA 95834, or by telephone at +1 (800) 952-5210.
