Why Choose WildCard?#
In China, the payment process is often the biggest pain point when subscribing to overseas services. Traditional international credit cards have high thresholds, while virtual card services like Dupay, VCard, PokePay, WasabiCard, and LocalCard usually require recharge through cryptocurrencies like USDT, which is complex and carries exchange rate fluctuation risks. More importantly, the stability of these services is often concerning, with payment failures or account restrictions occurring frequently.
In contrast, WildCard offers a simpler and safer option. It supports direct recharges through common domestic payment methods like Alipay and WeChat, without the cumbersome KYC identity verification. The registration and card opening process takes only a few minutes. More critically, WildCard's payment channels are optimized to effectively avoid risk control interceptions from overseas platforms (like xAI), ensuring a high payment success rate. Whether for subscription services or API recharges, WildCard provides stable and reliable support.

Steps to Apply for xAI Grok 3 API Access#
Before starting the recharge and card binding, you need to apply for xAI's API access. Here are the specific steps:
-
Visit the xAI Official Website and Register an Account
Open xAI Official Website, click the registration button, and create an account using your email or phone number. It is recommended to use an international email like Gmail to avoid verification issues that may arise with domestic emails. -
Submit API Access Application
After logging in, go to the API management page and find the "Apply for API Access" option. Fill in your usage scenario (such as developing applications, research projects, etc.) and basic information as prompted on the page. xAI will review the application content, which usually takes 1-3 business days. -
Wait for Approval
Once approved, you will receive an email containing your API key, and the recharge and card binding functions will be unlocked in your account backend. At this point, you can start configuring your payment method to use Grok 3's API services.
Using WildCard to Complete xAI API Recharge and Card Binding#
After obtaining API access, the next key step is to complete payment binding and balance recharge through WildCard. Here is a detailed tutorial:
Step 1: Register and Activate WildCard#
- Visit WildCard Official Website and click the "Register" button in the upper right corner.
- Enter your phone number (default +86), obtain a verification code, and submit the registration.

Step 2: Recharge WildCard Account#
- Log in to the WildCard backend, click on "My Cards" in the left menu, and go to the recharge page.
- It is recommended to recharge at least $25 for the first time, as xAI may charge a $5 pre-authorization fee when binding the card, and additional consumption may occur during API usage.
- Choose Alipay or WeChat for payment, enter the recharge amount (minimum $5), and scan the QR code to complete the recharge. WildCard's service fee is transparent, only 3.5%.
Step 3: Bind WildCard to xAI#
- Return to the xAI official website, log in to your account, and go to the "Billing and Payment" settings page.
- Click "Add Payment Method" and enter the card number, expiration date, and CVV code provided by WildCard.
- After submission, xAI will perform a pre-authorization verification (usually $5, which will be refunded after verification). Ensure that the card balance is sufficient to avoid binding failure.
- Once successfully bound, you can start recharging your API account or directly use the card balance to pay for API call fees.
WildCard's Versatility in Multiple Scenarios#
In addition to supporting xAI Grok 3 API recharges, WildCard can also be used to subscribe to other overseas services such as ChatGPT Plus, GitHub Copilot, Midjourney, and even Twitter and OnlyFans. Whether you are a developer, content creator, or a small to medium-sized business user, WildCard can meet diverse payment needs. Even better, it does not charge consumption fees, and withdrawals are processed in real-time, providing a smooth experience.
