OpenGateway Terms of Service

This document is the main contract for using OpenGateway’s platform, APIs, billing, accounts, and provider routing.

OpenGateway is a gateway, not the model operator. It routes requests to third-party LLM providers and does not guarantee provider availability, output quality, accuracy, legality, or suitability.

You represent that you are 16 or older, or that you have the consent of a parent, guardian, or legal representative where applicable law requires it. Team admins are responsible for team members, API keys, usage, and billing.

You own your Input and, as between you and OpenGateway, your Output, subject to upstream provider terms. Customer fine-tunes are also yours as between you and Sionic AI, but hosting and provider-side controls follow the upstream provider’s terms.

OpenGateway does not train on your content. Provider policies may differ, so provider choice matters.

The service uses prepaid credits and has no default SLA under the ToS. Liability is capped at fees actually paid in the prior 12 months.

Disputes require 30 days’ informal notice first. Korea-resident users use Seoul court or KCAB arbitration if elected; global users use AAA arbitration in New York. Class actions are waived, with batching for 75+ similar arbitration demands.

When to re-read: before production launch, team rollout, relying on model:"auto", changing providers, handling disputes, or after a 30-day material terms notice.

Version 1.4 | Effective Date: the Effective Date | Last Updated: June 13, 2026

These Terms of Service ("Terms") constitute a legally binding agreement between you ("User," "you," or "your") and Sionic AI Co., Ltd. ("Sionic AI," "Company," "we," "us," or "our"), a company organized under the laws of the Republic of Korea, governing your access to and use of the OpenGateway platform, APIs, and related services (collectively, the "Service").

1. Acceptance of Terms

1.1. By accessing, registering for, or using the Service, you acknowledge that you have read, understood, and agree to be bound by these Terms and all policies incorporated by reference, including the Acceptable Use Policy, Privacy Policy, and Payment Policy.

1.2. If you do not agree to these Terms, you must not access or use the Service.

1.3. Eligibility. OpenGateway is a developer platform intended for use by individuals aged 16 or older. By accepting these Terms, you represent and warrant that:

(a) You are 16 years of age or older, or you have the consent of a parent, legal guardian, or legal representative where required by applicable law; and
(b) You have the legal capacity, in your jurisdiction, to enter into these Terms.

1.4. Who "you" are. OpenGateway is built first for individual developers. Most users will sign up as a solo developer in their personal capacity, and these Terms bind you individually. If you choose to create or join a team or organization account, you represent and warrant that you have the authority to bind that organization to these Terms; in that case, "you" and "your" refer to both you individually and the organization you represent. Solo-developer use does not require an organization or company affiliation.

1.5. Your continued use of the Service after any modification to these Terms constitutes acceptance of the modified Terms, subject to the notice provisions in Section 15.

2. Service Description

2.1. OpenGateway is a developer platform that lets individual developers and teams call multiple large language model (LLM) providers through a single, OpenAI-compatible API. As of the Effective Date, the Service routes to eleven (11) provider integrations: openai, anthropic, azure, vertex-ai, sionic-ai, x-ai, minimax, kimi, deepseek, z-ai, and dashscope. The current sub-processor list is published as set out in the Data Processing Agreement Annex A and on the public Sub-processors page; the list above is non-exhaustive and may change with notice.

2.2. The Service includes the following capabilities:

(a) Unified API access to multiple LLM providers through a single endpoint;
(b) Unified billing and usage tracking across providers;
(c) Automatic failover and provider routing;
(d) API key management;
(e) Team-based account and billing management;
(f) Automatic model selection via the model: "auto" parameter (subject to Section 8); and
(g) Such additional features as may be introduced from time to time.

2.3. What the Service Is. OpenGateway acts solely as an intermediary gateway between you and third-party LLM providers. The Service routes your API requests to the selected LLM provider, returns the provider's responses to you, and manages billing and usage tracking.

2.4. What the Service Is Not. OpenGateway does not itself generate, create, or produce any LLM responses. We do not operate the underlying language models, and we do not control or guarantee the content, accuracy, completeness, or quality of responses generated by third-party LLM providers. The Service is not a substitute for professional advice of any kind.

2.5. OpenGateway does not store the content of your API requests (prompts) or API responses unless you explicitly enable request logging through the Service's logging features.

3. Account Registration

3.1. To use the Service, you must create an account. Account registration is facilitated through Auth0 and may include social login options (such as Google). You are responsible for ensuring the accuracy of the information provided during registration.

3.2. Team Accounts. The Service supports team-based accounts. If you create or administer a team account, you are responsible for:

(a) Managing team membership and access permissions;
(b) All activity conducted under your team account, including activity by team members;
(c) Ensuring that all team members comply with these Terms; and
(d) Billing obligations associated with the team account.

3.3. API Key Responsibility. You are solely responsible for maintaining the confidentiality and security of your API keys. You must:

(a) Treat API keys as confidential credentials;
(b) Not share API keys with unauthorized third parties;
(c) Promptly revoke and delete any API key that you believe has been compromised, and create a replacement key as needed; and
(d) Notify us immediately at privacy@sionic.ai if you suspect unauthorized use of your account or API keys.

3.4. You are liable for all charges, activity, and usage associated with your account and API keys, regardless of whether you authorized such activity, except where such unauthorized activity results directly from a breach of our security obligations.

3.5. You may not create multiple accounts to circumvent usage limits, billing obligations, or enforcement actions.

4. Acceptable Use

4.1. Your use of the Service is subject to the OpenGateway Acceptable Use Policy ("AUP"), which is incorporated by reference into these Terms. You agree to comply with the AUP in all respects.

4.2. Without limiting the AUP, you agree not to use the Service to:

(a) Violate any applicable law, regulation, or third-party right;
(b) Transmit content that is unlawful, harmful, threatening, abusive, defamatory, obscene, or otherwise objectionable;
(c) Attempt to gain unauthorized access to the Service, other accounts, or any systems or networks connected to the Service;
(d) Interfere with or disrupt the integrity or performance of the Service;
(e) Reverse-engineer, decompile, or disassemble any aspect of the Service;
(f) Use the Service to develop a competing product or service;
(g) Resell or redistribute access to the Service without our prior written consent;
(h) Use automated means to scrape, crawl, or otherwise extract data from the Service beyond normal API usage; or
(i) Circumvent any usage limits, quotas, or technical measures that the Service may apply.

4.3. You are solely responsible for ensuring that your API requests comply with the acceptable use policies and terms of service of all applicable LLM providers through which your requests are routed. Violation of a provider's terms may result in service disruption without liability to us.

5. Fees and Payment

5.1. Credit System. The Service operates on a prepaid credit system. You must purchase credits to use the Service. Credits are consumed based on your API usage in accordance with the applicable pricing schedule published on our website.

5.2. Payment Processing. All payments are processed through PayPal (PayPal, Inc.). Payment is accepted through your PayPal account only; we do not accept direct card payments, Venmo, Apple Pay, or Google Pay as payment sources. Each new payment requires you to log in to and approve the payment through your PayPal account; payment methods previously saved with the Service may remain usable. By making a payment, you authorize us and our payment processor to charge the applicable fees through your PayPal account.

5.3. Low-Balance Alerts. You may receive low-balance email alerts when your credit balance falls below a threshold. Credit top-ups are performed manually by you; the Service does not automatically purchase credits on your behalf.

5.4. Redeem Codes. Credits obtained through redeem codes are:

(a) Non-refundable;
(b) Non-transferable between accounts; and
(c) Subject to any additional terms specified at the time of issuance.

5.5. Taxes. All fees are exclusive of applicable taxes. You are responsible for paying all taxes, levies, and duties imposed by taxing authorities in connection with your use of the Service, except for taxes based solely on our net income.

5.6. Pricing Changes. We may modify our pricing at any time. Price changes will apply to credits purchased after the effective date of the change. Credits already purchased will be honored at their original value.

5.7. For complete details regarding billing, refunds, payment disputes, and credit policies, refer to the Payment Policy.

6. Intellectual Property

6.1. Your Input. You retain all right, title, and interest in and to the content you submit to the Service as API requests ("Input"). We claim no ownership of your Input.

6.2. Your Output. As between you and us, you own the content you receive through the Service in response to your Input ("Output," and together with Input, "User Content"). To the extent we have any residual rights in the Output, we hereby assign those rights to you, subject to (a) the upstream LLM provider's terms (Section 6.7) and (b) your compliance with these Terms, the Acceptable Use Policy, and applicable law.

6.3. License to Us. You grant us a limited, non-exclusive, worldwide, royalty-free license to process, transmit, route, and temporarily cache your User Content solely to the extent necessary to (a) provide the Service to you, (b) operate the Service (including billing, abuse detection, and security), and (c) comply with our legal obligations. This license terminates with respect to your User Content when you delete your account or the relevant data, subject to the retention schedule in the Privacy Policy and our backup-retention practices.

6.4. No Training on User Data by OpenGateway. OpenGateway will not use your User Content to train, fine-tune, or improve any machine learning models, and will not share your User Content with any third party for the purpose of training, fine-tuning, or improving any third party's machine learning models, without your explicit, prior written consent. This restriction applies to OpenGateway's own systems and to any party we contract with as a sub-processor for that purpose; it does not override the published policies of the upstream LLM providers (see Section 6.7). For the avoidance of doubt, this no-training commitment covers your prompts and completions (your User Content): OpenGateway will not use them to train AI models without your prior explicit consent. This commitment does not extend to operational metadata associated with your API requests (such as token counts, latency, model and provider identifiers, and timestamps), which we may use for billing, abuse prevention, reliability, and service improvement as described in the Privacy Policy.

6.5. Customer Fine-tunes. If you create or use a fine-tuned model through an upstream LLM provider by routing fine-tuning calls or training data through OpenGateway, you own that fine-tune as between you and Sionic AI. OpenGateway acts solely as a routing layer for those calls; we will not retain, replicate, share, or use the fine-tune metadata, training data, or resulting model weights for any purpose other than delivering your routing requests, and we will not train any of our own models on the fine-tune. The hosting, ownership, and access controls for the fine-tuned model itself are governed by the upstream provider's terms; you remain responsible for managing your relationship with that provider.

6.6. Our Service. We and our licensors retain all right, title, and interest in and to the Service, including all software, algorithms, interfaces, documentation, trademarks, and other intellectual property embodied in or associated with the Service. Nothing in these Terms grants you any right to use our trademarks, logos, or branding without our prior written consent.

6.7. Third-Party Model Outputs. The intellectual property rights governing Output generated by third-party LLM providers are also subject to the respective upstream provider's terms. Where the upstream provider's terms are more restrictive than Section 6.2 (for example, a provider that disclaims warranties about Output uniqueness or restricts commercial use of certain models), the upstream provider's terms govern that Output. We make no representations regarding your rights to use such Output beyond what is permitted by the applicable provider's terms.

6.8. Feedback. If you provide us with suggestions, ideas, or other feedback regarding the Service ("Feedback"), you grant us an unrestricted, irrevocable, perpetual, royalty-free license to use, modify, and incorporate such Feedback into the Service without obligation to you.

7. Third-Party Services

7.1. The Service routes your API requests to third-party LLM providers. These providers are independent third parties, not our agents, partners, or affiliates.

7.2. Provider Terms. Your use of each LLM provider through the Service is subject to that provider's own terms of service, acceptable use policies, and other applicable agreements. It is your responsibility to review and comply with the terms of each provider whose services you access through OpenGateway.

7.3. Pass-Through Obligations. Certain obligations imposed by LLM providers apply to downstream users. You agree to comply with all such pass-through obligations as communicated by us or as set forth in the applicable provider's terms.

7.4. No Warranty for Third-Party Services. We do not control and are not responsible for the availability, accuracy, quality, or content of responses provided by third-party LLM providers. Provider outages, deprecations, policy changes, or content moderation decisions are outside our control.

7.5. Provider Changes. LLM providers may modify, deprecate, or discontinue their models or services at any time. We will make commercially reasonable efforts to notify you of material provider changes that affect the Service, but we are not liable for any disruption caused by such changes.

8. model: "auto" Routing Disclaimer

8.1. The Service offers an automatic model selection feature accessible via the model: "auto" parameter (the "Auto Router"). The Auto Router selects an LLM model on your behalf based on factors such as provider and region availability and configured fallback ordering. The Auto Router operates on a best-effort, discretionary basis, and the factors it considers may change at any time.

8.2. Best-Effort Selection. The Auto Router operates on a best-effort basis. We do not guarantee that:

(a) Any specific model or provider will be selected for a given request;
(b) The selected model will produce the optimal response for your use case;
(c) Model selection will be consistent across identical or similar requests; or
(d) The Auto Router's selection will align with your specific requirements.

8.3. No Quality Guarantee. Automatic model selection does not constitute a representation or warranty regarding the quality, accuracy, or suitability of the selected model's response. You acknowledge that different models may produce materially different outputs for the same input.

8.4. User Responsibility. If your application requires a specific model, specific quality characteristics, or deterministic routing behavior, you should specify the model explicitly rather than relying on the Auto Router.

8.5. We may modify the Auto Router's selection criteria, algorithms, and available model pool at any time without prior notice.

9. Data and Privacy

9.1. Our collection, use, and processing of personal data are governed by our Privacy Policy, which is incorporated by reference into these Terms.

9.2. Data Processing. We process data transmitted through the Service solely for the purpose of delivering the Service to you. This includes routing requests, managing billing, providing usage analytics, and maintaining service reliability.

9.3. No Content Storage by Default. As stated in Section 2.5, we do not store the content of your API requests or responses unless you explicitly enable logging features. When logging is enabled, stored data is subject to the data retention and security practices described in the Privacy Policy.

9.4. Data Protection. We implement commercially reasonable technical and organizational measures to protect data transmitted through and stored within the Service. However, no system is completely secure, and we cannot guarantee absolute security.

9.5. If you process personal data of third parties through the Service, you are responsible for ensuring that you have a lawful basis for such processing and that your use complies with all applicable data protection laws, including but not limited to the EU General Data Protection Regulation (GDPR), the Korean Personal Information Protection Act (PIPA), and the Act on Promotion of Information and Communications Network Utilization and Information Protection (Network Act).

10. Service Availability

10.1. We strive to maintain high availability of the Service but provide it on a best-effort basis. We do not guarantee uninterrupted, error-free, or continuous access to the Service.

10.2. Planned Maintenance. We will use commercially reasonable efforts to provide reasonable advance notice of planned maintenance that may result in material service disruption, via email or in-service notification.

10.3. No Default SLA. These Terms do not include a service level agreement (SLA). If you require guaranteed uptime commitments, please contact us to discuss a separate SLA agreement.

10.4. The Service's availability depends in part on the availability of third-party LLM providers, cloud infrastructure, and network services that are outside our control.

10.5. We reserve the right to modify, suspend, or discontinue any aspect of the Service at any time. We will provide reasonable notice of any material changes or discontinuation, except in cases of emergency or where required by law.

11. Limitation of Liability

11.1. Liability Cap. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, OUR TOTAL AGGREGATE LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE SHALL NOT EXCEED THE TOTAL FEES ACTUALLY PAID BY YOU TO US DURING THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM.

11.2. Exclusion of Consequential Damages. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL WE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, REVENUE, DATA, BUSINESS OPPORTUNITIES, OR GOODWILL, REGARDLESS OF THE CAUSE OF ACTION OR THE THEORY OF LIABILITY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

11.3. Specific Exclusions. Without limiting the foregoing, we shall not be liable for:

(e) Any action taken by an LLM provider, including content filtering, model deprecation, or policy changes; or
(f) Losses arising from the Auto Router's model selection decisions.

11.4. Disclaimer of Warranties. THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

11.5. Some jurisdictions do not permit the exclusion or limitation of certain warranties or liability. In such jurisdictions, our liability is limited to the maximum extent permitted by law.

12. Indemnification

12.1. You agree to indemnify, defend, and hold harmless Sionic AI, its officers, directors, employees, agents, and affiliates from and against any and all claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys' fees) arising out of or relating to:

14.3. International Arbitration — Korea-resident Users. For Users domiciled in the Republic of Korea who elect arbitration in lieu of the court forum in Section 14.2, any dispute, controversy, or claim arising out of or relating to these Terms shall be settled by arbitration administered by the Korean Commercial Arbitration Board (KCAB) in accordance with the KCAB International Arbitration Rules in effect at the time of the arbitration:

(a) The seat of arbitration shall be Seoul, Republic of Korea;
(b) The arbitration shall be conducted in English;
(c) The tribunal shall consist of one (1) arbitrator; and
(d) The arbitral award shall be final and binding on both parties.

Neither party may participate as a class representative or class member in any class action with respect to any claim covered by these Terms.

14.6. Mass Arbitration Procedure. If, within a thirty (30) day period, seventy-five (75) or more substantially similar arbitration demands are filed against Sionic AI by Users represented by the same or coordinated counsel, the parties agree that the arbitration provider may, at its discretion, batch and stage proceedings (selecting an initial bellwether tranche of representative claims) to manage the docket efficiently. The parties agree to cooperate with such batching procedures and to share reasonable information necessary to administer them. The deadlines for filing individual arbitration demands shall be tolled while batched proceedings are pending.

14.7. Informal Resolution. Before initiating formal dispute resolution under Sections 14.2, 14.3, or 14.4, the parties agree to attempt to resolve any dispute informally by sending written notice to the other party describing the dispute and the proposed resolution.

16.4. Assignment. You may not assign or transfer these Terms or any rights or obligations hereunder without our prior written consent. We may assign these Terms without restriction, including in connection with a merger, acquisition, corporate reorganization, or sale of all or substantially all of our assets.
