1. Credits Are Non-Refundable
All credit purchases are final. Zetta API sells usage credits, not monetary deposits. Once credits are added to your account, they cannot be exchanged back for USD, USDT, or any other currency.
This is standard practice for API credit systems (similar to OpenAI, Anthropic, and other AI providers). You are purchasing the right to use our API service, not storing money.
2. What IS Refundable
We will issue a refund (in USDT TRC-20 to your original wallet) ONLY in these cases:
- Payment error: You were charged the wrong amount or charged twice for the same order (verified via blockchain).
- Service unavailable: Zetta API is fully down for > 24 consecutive hours (not including upstream provider outages). Refund is pro-rated for downtime.
- Fraudulent transaction: Your wallet was compromised and used without your authorization. Requires police report or equivalent documentation.
3. What Is NOT Refundable
- "I changed my mind" or "I don't need this anymore"
- "The AI model didn't give good results" — output quality depends on the upstream provider, not us
- "I used the wrong model" — you can switch models anytime at no extra cost
- Partial credit balances — you bought credits, use them anytime
- USDT transaction fees (gas/network fees) — these go to the blockchain, not to us
4. USDT Payment Disputes
USDT TRC-20 transactions are irreversible by nature. Once confirmed on the blockchain, we cannot "charge back" a transaction. If you sent USDT to the wrong address, we cannot recover it.
Always verify: our USDT address is displayed on the payment page and in your dashboard. Check the first 6 and last 4 characters before sending.
If you believe a payment was processed incorrectly, contact us within 48 hours of the transaction with: your order ID, transaction hash (TxID), and wallet address used.
5. How to Request a Refund
Email refund@zetta-api.com with:
- Your account email
- Order ID (from your dashboard billing history)
- USDT transaction hash (TxID from TronScan or your wallet)
- Reason for refund request
- Supporting evidence (screenshots, blockchain explorer link)
We respond within 5 business days. Approved refunds are sent to your original USDT wallet within 3 business days.
6. Credit Expiration
Credits do not expire while your account is active. If your account is inactive (no API calls) for 12 consecutive months, we reserve the right to expire your remaining credits after sending 3 email warnings (30, 14, and 7 days before expiration).
7. Chargebacks
Filing a fraudulent chargeback or payment dispute after receiving valid service constitutes fraud. We reserve the right to permanently suspend your account and report abuse to relevant payment networks.

- 欺诈交易：钱包被盗用。需提供警方报案证明。
3. 不可退款情况
