Refund Policy
Last updated: July 14, 2026
Operator: 半页酥 (byesu) · Contact: bysu721@gmail.com
This Refund Policy applies to byesu.com and its related subdomains and APIs (the "Service"), operated by 半页酥 (byesu). It forms part of our Terms of Service. Capitalized terms have the meanings given there.
1. How Billing Works
The Service operates on a prepaid, pay-as-you-go model. You add funds ("top-ups") to your account balance, and usage fees are deducted from that balance as you make API requests, at the prices published on the Service at the time of each request. Balance is a prepaid credit toward future usage of the Service; it is not a bank deposit and does not accrue interest.
2. Consumed Usage Is Not Refundable
Charges for API requests that were successfully processed and returned a response are final and non-refundable. This includes cases where you are dissatisfied with the quality, accuracy, or usefulness of model output: we route requests to third-party AI models operated by upstream providers and cannot control or guarantee the content those models produce. Once compute has been consumed by an upstream provider, we incur the corresponding cost regardless of how you evaluate the result.
If you believe you were charged for a request that failed, or that a charge was metered incorrectly, contact support with the request details and we will investigate. Verified billing errors are corrected by crediting your balance.
3. Failed Tasks and Unsuccessful Requests
Video generation tasks are billed when the task is submitted. If a video task fails — for example, the upstream provider returns an error or the asynchronous task terminates unsuccessfully — the charge for that task is automatically credited back to your account balance. This happens without any action on your part; you do not need to file a request. If you believe a failed video task was not automatically credited, contact support with the task ID and we will review it.
Image generation and other API requests: requests that are not successfully processed are generally not billed. If you believe you were charged for a request that did not complete successfully, contact support with the request details and we will investigate; verified errors are corrected as described in Section 2.
A task that completes successfully but produces output you do not like is a completed task, not a failed one, and is not eligible for a refund under this section.
4. Refund of Unused Balance
Refunds of unused balance are considered case by case at our discretion. We neither promise refunds of unused balance nor categorically refuse them: contact support at bysu721@gmail.com with the email address on your account and your top-up records, and we will review your situation.
Promotional credits, bonus balance, and compensation credits issued by us have no cash value and are never refundable.
Where a refund of unused balance is approved, it is issued via the original payment method where technically possible. For cryptocurrency (USDT) top-ups, refunds are sent on the same network to an address you confirm in writing, and on-chain network fees may be deducted. If a refund via the original method or network is not technically feasible, we may, at our discretion, agree on an alternative arrangement with you in writing.
5. Account Termination
If we terminate your account for fraud, sanctions evasion, or the generation or distribution of illegal content, any remaining balance is forfeited to the extent permitted by applicable law. If we terminate your account for other violations of the Terms of Service or the Acceptable Use Policy, remaining balance is handled case by case. If you close your account voluntarily while in good standing, remaining balance is handled under Section 4.
6. How to Request a Refund or Dispute a Charge
Send your request to bysu721@gmail.com and include:
- the email address on your account;
- the top-up record or transaction reference (for balance refunds), or the request/task ID and timestamp (for billing disputes); and
- a brief description of the issue.
We may ask for additional verification to confirm account ownership before processing any refund.
7. Processing Timelines
We aim to acknowledge refund requests within 2 business days and to resolve them within 7–14 business days. The time it takes for funds to arrive after a refund is issued depends on the payment method and its operator (blockchain confirmation times, payment-platform processing, or card-network posting times) and is outside our control.
8. Chargebacks and Payment Disputes
Please contact us before opening a dispute with a payment platform — most issues are resolved faster through support. Initiating a payment dispute while continuing to consume the Service may result in suspension of your account pending resolution.
9. Changes to This Policy
We may update this Refund Policy from time to time. Changes apply to top-ups made after the change takes effect and will be announced on the Service.
