Why Choose Claude 4 API?#
Claude 4 API, with its outstanding conversational abilities, code generation capabilities, and multimodal processing functions, has become the ideal choice for developers, content creators, and enterprises. Compared to other AI models, Claude 4 excels in security, contextual understanding, and multilingual support, making it particularly suitable for scenarios requiring high-quality text generation or complex task handling. However, Anthropic's payment system requires international credit cards (such as Visa or MasterCard), which poses a significant barrier for domestic users. Traditional UnionPay cards often cannot make direct payments due to currency restrictions or risk controls, making virtual credit cards that support Claude the preferred solution for domestic users.
WildCard: A Payment Tool Tailored for Domestic Users#
WildCard is a virtual credit card platform designed specifically for domestic users, perfectly solving the payment difficulties of overseas software subscriptions. Unlike platforms that require complex operations through USDT top-ups (such as Dupay, VCard, PokePay, WasabiCard, LocalCard), WildCard supports direct top-ups via Alipay and WeChat, making it extremely easy to use, even for beginners. Additionally, WildCard's payment channels are optimized for high stability, rarely encountering payment interception issues, and do not require cumbersome KYC verification (optional Alipay facial verification can be used to increase limits), maximizing user privacy protection.
Opening a Card and Top-Up: Simple Three Steps#
-
Register an Account: Visit Claude Subscription Virtual Card Recommendation, click the "Register" button in the upper right corner, use a mainland phone number (+86) or a Hong Kong phone number (+852) to receive a verification code, and complete the registration. Don't forget to enter the invitation code LEIXUE to enjoy card opening discounts.
-
Select a Package and Payment: After logging in, go to the "My Cards" page, choose a 1-year ($11.99) or 2-year ($16.99) package, and use the invitation code LEIXUE to enjoy a $1 discount. Pay the card opening fee via Alipay or WeChat QR code, and the system will automatically generate virtual card information (card number, expiration date, CVV code).
-
Top-Up and Use: The new card balance is zero and needs to be topped up before use. It is recommended to top up $25 initially to cover the pre-authorization fee for the Claude 4 API subscription (approximately $5) and the actual subscription fee. The top-up fee is only 3.5%, and any unused balance can be refunded in real-time via Alipay without additional charges.

Common Questions and Solutions#
- What to do if payment fails? If you encounter a payment failure, check the WildCard transaction records. If there is a record but it still fails, check the reason for failure or try switching to a home network IP.
- What to do if the balance is insufficient? Ensure that the top-up amount covers the pre-authorization fee and subscription fee; it is recommended to top up $25 initially.
- How long does a refund take? Due to the processes of the US payment system, refunds typically take 14-21 business days, and in some cases, it may take up to 30 days. WildCard charges a 2% refund fee for this.
