# Account and Vouchers

## 1. How do I obtain invitation / registration vouchers?

* New users:
  * After registering with an invitation code and binding GitHub, you will receive a \$2 voucher
  * After completing the questionnaire, you will receive an additional \$1 voucher
* Existing users:
  * When a new user registers through an invitation link or by entering an invitation code, and binds GitHub, the existing user will receive a \$1 voucher
  * The invited user's first 5 top-ups will also grant vouchers to the existing user at a certain percentage (subject to the campaign rules)

For details, please refer to the campaign page: [https://jiekou.ai/referral](https://jiekou.ai/referral)

## 2. Why hasn’t the \$2 voucher arrived after binding GitHub?

Please confirm:

1. You have completed GitHub binding
2. You entered an invitation code during registration (if you did not enter one during registration, you may not be able to receive it; you can contact customer support to have it reissued)
3. Refresh the page or log in again to check
4. How do I use vouchers?

Vouchers are used to offset billing charges incurred when your account calls models on a pay-as-you-go basis. They will be automatically applied for deduction within their validity period.

## 4. Why does the voucher show as 0 even though I clearly haven’t used it up?

There may be a system delay or display bug. Please provide your UUID and contact customer support for verification. There have been past cases where a bug caused abnormal display; the actual balance may still exist.

## 5. Are there discounts for individual developers?

Subscription package campaigns will be launched around the Spring Festival. Please follow the subscription package discount policies at that time.

## 6. Are there monthly or annual plans?

Subscription package campaigns will be launched around the Spring Festival. Please follow the subscription package discount policies at that time.
