# Youyun API Refund Policy

Last updated: July 3, 2026

This Refund Policy applies when you purchase, top up, or use API quota, model calls, subscriptions, packages, or other paid services on Youyun API (hereinafter referred to as "this platform" or "we").

Please read this Policy carefully before topping up or purchasing. By completing payment, you acknowledge that you understand and agree to this Policy.

## 1. Billing Explanation

This platform provides services such as AI model API gateway, unified calls, usage statistics, group multipliers, and balance management. Fees are usually calculated based on model, group, multiplier, Token usage, request type, upstream cost, and rules published by the platform.

Unless otherwise stated on the page, top-ups on this platform are paid in RMB and converted into usable quota according to the rules published by the platform. The current display basis is "1 RMB top-up = 1 USD quota". The specific result is subject to the payment page, order page, billing page, and backend records.

Model prices, multipliers, discounts, and availability may change due to upstream services, exchange rates, promotions, costs, or policy changes. Call fees already incurred before an adjustment will not be automatically refunded because of subsequent price changes.

## 2. Circumstances Eligible for Refund Application

Subject to laws and regulations and this Policy, you may apply for a refund in the following circumstances:

- Duplicate payment or abnormal payment amount
- Payment succeeded but quota was not credited, and after verification it cannot be reissued
- Mistaken top-up where no paid quota has been used, and the application is submitted within 7 days after payment completion
- Long-term service unavailability caused by this platform, where you have not actually consumed the corresponding paid quota
- Other circumstances where laws or regulations require a refund or where we confirm in writing that a refund is available

## 3. Circumstances Not Eligible for Refund

Refunds are usually not supported in the following circumstances:

- Actually consumed API call fees, Token fees, model fees, or delivered services
- Gift quota, coupons, campaign rewards, test quota, compensation quota, or non-cash purchased quota
- Losses caused by your account, password, API Key, client, network, proxy, code, parameters, model selection, or configuration errors
- Consumed fees caused by upstream model rate limiting, third-party service policy adjustments, model removal, price changes, or output quality not meeting subjective expectations
- Account restrictions caused by violation of service terms, abuse, attacks, fraudulent use, arbitrage, resale, illegal content, or risk-control bans
- Orders for which invoices have been issued and cannot be lawfully reversed or processed through necessary financial procedures
- Applications submitted after the application period or without valid order, account, payment, and issue proof materials
- Other circumstances where laws and regulations allow no refund

## 4. Partial Refunds

If part of the quota in an order has been used, we may calculate the refundable amount based on backend bills, call records, balance changes, consumption order of gift quota, and actual paid amount.

Partial refunds usually return only unused paid balance. Consumed fees, payment channel handling fees, invoice taxes, promotional deductions, gift quota, and incurred third-party costs may be deducted according to law or actual circumstances.

## 5. Application Process

You can submit a refund application through:

- Contact: yycodenet@gmail.com
- Required information: registered account, order number, payment time, payment amount, payment channel, refund reason, issue screenshots or related proof

After receiving your application, we will verify it based on the order, bill, call records, payment status, and account status. If materials are incomplete, we may ask you to provide additional information.

## 6. Processing Time

We usually complete initial review within 7 business days after receiving complete application materials. Complex orders, disputed orders, payment channel exceptions, invoice processing, risk-control verification, or third-party confirmation may require more time.

After refund approval, funds are usually returned through the original payment route. The actual arrival time is subject to the processing time of the payment institution, bank, or third-party payment channel.

## 7. Obligation to Confirm Before Top-up

Before topping up or purchasing, please confirm:

- Whether the account is correct
- Whether the amount matches your expectation
- Whether you understand the model, group, multiplier, and billing rules
- Whether the client, API Key, Base URL, network environment, and request parameters are configured correctly
- Whether the paid service meets your business needs

Misuse, misconfiguration, or subjective dissatisfaction caused by insufficient confirmation does not automatically constitute a refund reason.

## 8. Disputes and Exception Handling

If you believe billing is incorrect, please contact us as soon as possible and provide request ID, call time, model name, order number, billing screenshot, or log information. We will verify based on backend records.

Initiating chargebacks, complaints, malicious disputes, or third-party payment reversals without prior communication may result in account suspension, balance freeze, service restriction, or further verification.

## 9. Policy Updates

We may update this Policy due to changes in business, laws and regulations, payment channels, upstream models, or platform billing rules. The updated Policy will be published on the page or notified by reasonable means. Policy updates do not affect refund handling results that were lawfully confirmed before the update.
