How to Top Up

Sign in to the Open Platform console, open Top Up, and choose either a direct top-up or a resource pack. Pay with WeChat Pay, then check Order Management to confirm that your points have arrived.

Top-up steps

1. Sign in or register in the Open Platform console.
2. Select Top Up from the left navigation.
3. Choose a direct top-up or a resource pack, confirm the amount and points, and submit the order.
4. Scan the payment QR code with WeChat and complete the payment.
5. Open Order Management and confirm that the order status is Points credited.

Points belong to your company or team. API and MCP calls under the same customer account share one points balance.

Choose a direct top-up

Direct top-ups use the rate ¥1 = 10,000 points, with a minimum top-up of ¥20.

The permanent points credited through a direct top-up do not expire. They are suitable for occasional use or a temporary balance increase. If your account also has resource-pack points, those points are used before permanent points.

About resource packs

Larger resource packs include more bonus points.

A resource pack becomes active as soon as its points are credited. You may have multiple active packs at the same time.

Each pack has its own validity period. A new pack does not wait for an existing pack to expire before becoming active.

Point usage rules

• The baseline exchange rate is ¥1 = 10,000 points. Resource packs include bonus points on top of this baseline.
• API and MCP calls share one points balance and deduct points based on actual usage.
• If multiple resource packs are active, the pack that expires first is used first.
• After all resource-pack points have been used, the system uses permanent points from the account.
• Unused resource-pack points can no longer be used after the pack expires. Choose a pack based on your expected usage.

Permanent points are not tied to a resource pack and do not expire. They may be obtained through direct top-ups, business agreements, promotions, or compensation.

Refund policy

Self-service refunds are not currently available. Contact customer support to submit a refund request.

Resource-pack refunds

• A resource pack is eligible for a refund only during its validity period. Requests are not accepted after the pack expires.

• The refund is based on the unused cash value of the resource pack:

  Refund = amount paid - cash value of points used

• Points granted through discounts, multipliers, or promotions have no independent cash value and are not included in the refund amount.

• If the cash value already used is equal to the amount paid, the refundable amount is zero.

• Free resource packs issued through promotions, compensation, or gifts are not refundable.

Permanent-point refunds

• Permanent points obtained through a paid direct top-up may be refunded based on the unused balance from that order.

• The refund is calculated by deducting the amount used from the amount paid:

  Refund = amount paid - amount used

• If the full balance from the order has been used, the refundable amount is zero.

• Permanent points issued through promotions, compensation, or business grants have no cash value and are not refundable.

Customer support will calculate the final refund amount based on the amount paid, point usage, and, where applicable, the resource pack's validity period. Include your customer account, order number, and reason for the refund when submitting a request.

FAQ

Can I request an invoice?

Yes. Contact customer support to request an invoice.

Which resource pack is used first if I have more than one?

The system uses the resource pack that expires first, reducing the risk of losing unused points when a pack expires.
