8. Refund Policy

FlintAPI is a prepaid service. The following refund terms apply:

8.1 7-Day No-Questions Refund

New users may request a full refund of their initial top-up amount within 7 calendar days of the payment, for any reason. This applies only to the first recharge and only if cumulative API usage during that period is below 10% of the recharged amount. Submit your request to support@flintapi.ai.

8.2 Balance Refund

Remaining account balances are refundable upon request. Any promotional or bonus credits are excluded from the refund calculation. Refunds are processed in USDT (TRC20) to an address you provide. A minimum refund amount of 10 USD equivalent applies. Processing time is up to 15 business days.

8.3 USDT (TRC20) Refund Process

1. Submit a refund request to support@flintapi.ai from your registered email, specifying the refund amount and your TRC20 USDT wallet address.
2. Our team will verify your account balance and usage within 3 business days.
3. Upon approval, USDT refund will be sent to your TRC20 address. You will receive a transaction hash (TXID) for confirmation.
4. The exchange rate used: the amount originally paid in USD will be refunded at 1:1 in USDT. If the original payment was in another currency, the prevailing USDT/USD market rate at the time of refund applies.

8.4 Other Refund Circumstances

• Service Outage: If FlintAPI experiences a confirmed service outage exceeding 72 consecutive hours caused solely by our infrastructure, you may request a prorated refund for the affected period.
