Automatic Refunds

Fees incurred under the following circumstances will be automatically refunded to your account balance (no manual application required):
  • API call failure — failure caused by BizyAir platform-side errors
  • Async task with no output — the task failed to produce any AI output due to a platform-side fault
  • System timeout — the task was interrupted by a server-side timeout
  • 5xx server error — any HTTP 500+ response is not billed
  • Platform-caused forced interruption — interruption due to platform maintenance or failure
Automatic refunds do not apply to the following:
  • (a) User-side errors: invalid input, authentication failure, content-policy violation
  • (b) Rate limit or insufficient balance: failure caused by hitting RPD/RPM limits or account balance depletion
  • (c) Third-party model provider fault: faults of the third-party model itself (rather than the BizyAir platform side)
  • (d) Low-quality but existing output: tasks that produced valid AI output even though the quality did not meet expectations

​
Client Timeout vs. System Timeout

Client timeout and system timeout are two different situations:
  • System timeout (server-side cause) → automatic refund
  • Client timeout (your network, proxy, browser, or gateway cause) → no automatic refund
If you use synchronous blocking mode and the HTTP request is interrupted by local network latency, connection drops, or client timeout, the task may still complete successfully in the cloud. In this case, the task is not considered failed and no refund is granted.

​
Tips for Best Results

To help you make the most of your account balance, we recommend:

​
Before Running

  • Review the model’s API reference docs to confirm parameter requirements and value ranges
  • Try a low-cost dry run first (low resolution, num_images=1, short duration)
  • Fix seed for reproducibility when troubleshooting
  • For long videos or multi-step sampling, validate the effect at a small resolution before scaling up

​
Understanding Model Output

AI model output can vary significantly depending on input parameters:
  • Start from the model’s recommended parameters and adjust step by step
  • Check the best practices in the model documentation
  • Test at a low resolution first, then generate the final version once the result is satisfactory
If the result is not as expected, the suggestions above can help improve future generations. However, “unsatisfied with output quality” is not a valid refund reason — as long as the task produced valid output, it is considered a successful call.

​
Balance Policy

​
Balance Validity

Once the balance validity expires, the unused balance will be cleared automatically and is irrevocable. Please check the validity in “My Wallet” in time.

​
Balance Is Non-refundable for Cash

Unless required by mandatory provisions of applicable law, all paid fees (including the pre-paid top-up balance) are non-refundable for cash.

​
Balance Is Non-transferable

Balance is an account-level asset and is not transferable, non-withdrawable, and cannot be exchanged for cash.

​
Invoiced Top-ups Cannot Be Refunded

If an invoice has already been issued after a top-up, that top-up cannot be refunded. Please confirm the invoice information is correct before submitting an invoice application.

​
Balance Consumption Order

When multiple balance sources coexist, they are deducted in the following order (those with shorter validity are consumed first):
  1. Bonus balance
  2. Purchased balance

​
Impact of Refunds on User Tier

A refund removes the corresponding amount from your “30-day cumulative top-up”. If the refunded order is still within the most recent 30-day window, the system will recalculate the effective balance and may trigger a user-tier downgrade.

​
Special Circumstances

​
Platform-wide Service Interruption

If, due to BizyAir’s gross negligence, a platform-wide service interruption lasts more than 24 consecutive hours and prevents you from using the service, you may apply (without BizyAir’s consent) for:
  • A pro-rata extension of the validity period of the unused top-up balance corresponding to the affected period
  • Or the conversion of such top-up balance into non-cash account balance

​
Price Adjustment

BizyAir reserves the right to adjust service pricing. Price adjustments will be notified 30 days in advance via announcement or email. Balances purchased before a price adjustment remain valid and do not depreciate, but the unit consumption rate (the fee per call) will be calculated according to the new rate in effect at the time of the call. If you do not accept the adjusted price, you may stop using the service before the new price takes effect.

​
Anti-fraud & Compliance

If BizyAir has reasonable grounds to suspect that your account is involved in fraudulent purchases, money laundering, credit card theft, chargeback abuse, malicious exploitation of platform vulnerabilities, or using multiple accounts to farm promotional balances, BizyAir may:
  • Immediately suspend or terminate your account
  • Freeze the related balance (whether top-up or bonus)
  • Refuse refunds
  • Report to relevant regulators or law enforcement
If a subsequent investigation confirms that no violation occurred, BizyAir will restore the affected balance and lift the suspension.

​
Billing Dispute Appeal

If you believe a charge is incorrect, you may dispute it within 30 days after the charge appears in your account ledger:
  1. Go to Profile → My Bills and find the corresponding deduction record
  2. Copy the request_Id of that task
  3. Submit the dispute via:
Charges not disputed within the 30-day period will be deemed final and accepted by you. For accepted disputes, BizyAir will make a refund or fee adjustment within a reasonable period and at its reasonable discretion.
