These Terms of Service (“Terms”) constitute a legally binding agreement between you (“User”, “you”, or “your”) and the Company governing your access to and use of the Service. By accessing or using the Service, you confirm that you have read, understood, and agreed to be bound by these Terms.

1. Overview of the Service

YossGate provides a unified, developer-centric artificial intelligence API aggregation and gateway service. The Service allows registered users to interact with third-party generative foundation models and application programming interfaces (“APIs” or “Models”) through an OpenAI-compatible routing architecture. The Company reserves the right to add, update, modify, or deprecate available Models from the Service at any time based on upstream availability and operational requirements.

2. Eligibility

You must be at least 18 years of age (or the age of legal majority in your jurisdiction) to form a binding contract with the Company. By agreeing to these Terms, you represent and warrant that:

• You have the full power and legal capacity to enter into these Terms;
• You have not previously been suspended, banned, or terminated from the Service;
• Your registration and use of the Service comply with all applicable local, national, and international laws, regulations, and sanctions.

If you are entering into these Terms on behalf of a company, partnership, or legal entity, you represent and warrant that you hold sufficient corporate authority to legally bind that entity to these Terms.

3. Accounts and Security

To access API keys and core features, you must register an account. During registration, you must provide accurate, complete, and current contact details, including a valid email address.

You are solely responsible for maintaining the confidentiality of your account credentials, passwords, and API keys. You accept full responsibility for all activities, token consumptions, and liabilities that occur under your account or through your API keys. If you suspect any unauthorized access or security compromise, you must notify us immediately at support@yossgate.com .

4. Billing, Credits, and Payment

4.1 Prepaid Credits and Top-Up Limits

Accessing Models requires purchasing prepaid API platform credits (“Credits”).

• Transaction Limits: Minimum purchase per transaction is US$5.00; maximum purchase per transaction is US$25,000.00.
• Refund Window: Refund requests for eligible, unused Credits must be submitted within twenty-four (24) hours of the transaction. After 24 hours, or once Credits have been consumed, all balances are strictly non-refundable.
• Payment Processing Surcharges: Third-party payment processor fees and gateway charges are non-refundable under all circumstances.

4.2 Expiration and Auto Top-Up

• Validity Period: Purchased Credits remain valid for three hundred and sixty-five (365) days. YossGate reserves the right to retire and expire unused Credits remaining after 365 days.
• Auto Top-Up: If enabled, you authorize YossGate to automatically charge your designated payment method when your available balance falls below your specified balance threshold. You may disable Auto Top-Up at any time in your dashboard.

4.3 Cryptocurrency Payments (Strictly Non-Refundable)

Payments made using cryptocurrency (e.g., USDT, USDC, BTC, ETH) are strictly non-refundable. You represent and warrant that any cryptocurrency utilized originates from lawful sources and does not represent proceeds of illegal activity.

5. Model Terms and Upstream Compliance

5.1 Flow-Down Obligations

The Service routes requests to external foundation models operated by independent third-party providers (including OpenAI, Anthropic, Google, DeepSeek, Meta, and others). By using any Model via the Service, you agree to strictly comply with the specific terms of service and acceptable use policies published by each respective upstream model provider.

5.2 Model Availability and Disclaimers

Models are provided on an “as available” basis. Upstream providers may modify, throttle, or terminate model availability without notice. YossGate shall have no liability for interruptions, output quality issues, hallucinations, or upstream model deprecations.

6. User Content, Privacy, and Zero Data Retention

6.1 Ownership of Prompts and Output

You retain all ownership rights in the text, data, code, or images you submit to the Service (“Input”). Ownership of generated responses (“Output”) is determined by the applicable terms of the underlying model provider.

6.2 Zero Data Retention and No Model Training

YossGate operates under a strict Zero Data Retention philosophy for model training:

• No Training: YossGate does not sell, use, or feed your Prompts or Outputs to train, retrain, or improve any machine learning models.
• Ephemeral Streaming: Requests are processed and streamed in-memory directly to upstream providers. We do not maintain persistent databases of your conversational contents, retaining only transient billing metadata (token counts, timestamps, HTTP status codes).

6.3 Representations Regarding Input

You represent and warrant that your Input does not infringe intellectual property rights, violate privacy laws, or contain prohibited content under our Acceptable Use Policy.

7. Prohibited Conduct

You agree not to:

• Use the Service for any unlawful, fraudulent, or harmful purpose;
• Resell raw API access or operate unauthorized competing services using scraped data;
• Attempt to circumvent platform rate limits, security safeguards, or billing mechanisms;
• Conduct prompt injection, adversarial jailbreaking (“red-teaming”), or malicious probing intended to bypass upstream safety filters without express authorization;
• Reverse engineer, decompile, or disassemble any aspect of the YossGate platform architecture;
• Introduce malware, viruses, or malicious scripts into the network infrastructure.

Violations of this section may lead to immediate account termination without refund and legal action.

8. Suspension and Termination

YossGate reserves the right to suspend or terminate your account and API access immediately, with or without notice, if you breach these Terms, our Acceptable Use Policy, or if required by law. Upon termination for breach, all remaining Credits in the account are immediately forfeited.

You may terminate your account at any time by contacting support. Termination does not relieve you of the obligation to pay accrued fees.

9. Disclaimers and Limitation of Liability

9.1 Warranty Disclaimer

THE SERVICE IS PROVIDED ON AN “AS IS” AND “AS AVAILABLE” BASIS. YOSSGATE EXPRESSLY DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT SHALL YOSSGATE OR ITS AFFILIATES BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES (INCLUDING LOSS OF PROFITS, DATA, OR BUSINESS OPPORTUNITIES).

YOSSGATE’S TOTAL CUMULATIVE LIABILITY FOR ALL CLAIMS ARISING UNDER THESE TERMS SHALL BE CAPPED AT THE GREATER OF:

• (B) ONE HUNDRED UNITED STATES DOLLARS (US$100.00).

10. Governing Law and Dispute Resolution

These Terms and any dispute or claim arising out of or in connection with them shall be governed by and construed in accordance with the laws of the Republic of Singapore, without giving effect to conflict-of-law principles.

Any dispute arising out of or in connection with this contract, including any question regarding its existence, validity, or termination, shall be referred to and finally resolved by arbitration administered by the Singapore International Arbitration Centre (SIAC) in accordance with the Arbitration Rules of the Singapore International Arbitration Centre for the time being in force.
