Why Choose Claude 4 API?#
Claude 4 API has become the ideal choice for developers, content creators, and enterprises due to its outstanding conversational abilities, code generation capabilities, and multimodal processing features. 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 is 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 (such as Dupay, VCard, PokePay, WasabiCard, LocalCard) that require complex operations through USDT recharge, WildCard supports direct recharges via Alipay and WeChat, with a very low operational threshold, suitable for users with no prior experience. In addition, 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 to increase limits), maximizing user privacy protection.
Opening an Account and Recharging: Simple Three Steps#

Recharge and Use: The new card balance is zero and needs to be recharged before use. It is recommended to recharge $25 for the first time to cover the pre-authorization fee for the Claude 4 API subscription (about $5) and the actual subscription fee.
