1. Prepaid Credits and Transaction Limits

Accessing generative AI models through YossGate APIs requires purchasing prepaid Credits. All purchases are denominated in US Dollars (USD) or equivalent supported currencies.

• Minimum Top-up: The minimum purchase amount per transaction is US$5.00.
• Maximum Top-up: The maximum purchase amount per transaction is US$25,000.00.
• Review Prior to Payment: You will have the opportunity to review and confirm the total charge, including applicable transaction costs, before completing the checkout process.

2. Refund Eligibility and Conditions

2.1 24-Hour Refund Window

Because API Credits provide immediate access to cloud computing and third-party foundation models:

• A refund request for unused, unconsumed Credits must be formally submitted within twenty-four (24) hours of the transaction completion.
• After the expiration of the 24-hour window, or once Credits have been partially or wholly consumed by API calls, the purchased Credits become strictly non-refundable.

2.2 Payment Processing Fees Are Non-Refundable

All refunds are subject to third-party payment gateway costs. Payment processing fees, merchant fees (e.g., Stripe, credit card interchange fees), and transaction surcharges are non-refundable under all circumstances. Only the net principal balance of eligible, unused Credits will be returned.

2.3 Expiration of Credits

Prepaid Credits remain valid for three hundred and sixty-five (365) days from the date of purchase. YossGate reserves the right to expire and retire Credits that remain inactive or unused after 365 days. Expired Credits cannot be refunded, extended, or transferred.

3. Cryptocurrency Payments (Strictly Non-Refundable)

CRITICAL NOTICE: Payments made using Cryptocurrency (including but not limited to USDT, USDC, BTC, or ETH) are STRICTLY AND ABSOLUTELY NON-REFUNDABLE, without exception.

Due to blockchain finality, price volatility, and anti-money laundering (AML) protocols, transactions completed via cryptocurrency cannot be reversed, canceled, or refunded once broadcast to the network. By selecting cryptocurrency as your payment method, you represent and warrant that the source of funds is lawful and you irrevocably waive any claim to a refund or chargeback.

4. Auto Top-Up

If you enable the optional “Auto Top-up” feature in your dashboard, you authorize YossGate to automatically charge your designated payment method when your available account balance drops below your pre-configured threshold.

• Credits acquired via Auto Top-up are subject to the standard 24-hour refund window for unused balances.
• You may reconfigure, pause, or cancel Auto Top-up at any time in your account settings; cancellations take effect immediately for subsequent cycles.

5. Account Termination and Refunds

• Voluntary Account Closure by You: If you voluntarily close or terminate your account, any eligible remaining unused Credits (excluding cryptocurrency payments and minus processing fees) will be refunded to your original payment method within thirty (30) business days.
• Termination for Breach: If YossGate suspends or terminates your account due to a violation of our Terms of Service, Acceptable Use Policy, fraudulent activity, API resale without authorization, or malicious attacks, all remaining Credits and account balances are completely forfeited and non-refundable.

6. Technical Anomalies and Billing Corrections

In strictly verified technical scenarios, YossGate will issue account balance adjustments:

• Duplicate Deductions: If system logs confirm that an internal gateway bug or routing error caused duplicate token billing on a single API call, the erroneously billed Credits will be credited back to your platform balance.
• Prolonged Platform Downtime: If a widespread, catastrophic platform failure on YossGate’s infrastructure prevents API access for an extended duration, reasonable compensation in the form of platform Credits may be granted upon management review.
• Unauthorized Account Access: In cases of alleged unauthorized billing, you must notify support@yossgate.com in writing within seven (7) calendar days with valid substantiating evidence.

7. Processing Times for Approved Refunds

Once a refund is approved by our billing department, the funds are transmitted back to the original funding source:

• Credit / Debit Cards: Typically 5 to 10 business days, depending on your issuing bank’s settlement cycle.
• Alternative Payment Methods: Typically 3 to 7 business days.
