March 2025 Latest Domestic OpenAI API Top-up Tutorial

With the rapid development of artificial intelligence technology, OpenAI's API and ChatGPT Plus have become indispensable tools for many domestic developers, content creators, and business users. However, due to the unique payment environment in the country, directly using bank cards to subscribe to overseas services often encounters obstacles, such as payment failures and card rejections. The good news is that there are already some solutions specifically designed for domestic users to address this pain point, among which WildCard is widely regarded as one of the most stable and convenient options available. This article will detail how to recharge OpenAI API and subscribe to ChatGPT Plus through WildCard, guiding you step by step to unlock the convenient channel for overseas AI services.

Why Choose WildCard?#

For domestic users, the biggest challenge in subscribing to overseas services lies in the payment process. Traditional Visa or Mastercard often face restrictions during cross-border payments, while virtual cards like Dupay, VCard, PokePay, WasabiCard, LocalCard, and Chicha can also be used, but most require recharging through USDT (a cryptocurrency), which is complex and not very intuitive. Not to mention that some services have questionable stability, and after recharging, there may be risks of card suspension or payment failure.

In contrast, the advantages of WildCard are obvious:

Supports domestic payment methods: You can recharge directly using Alipay or WeChat, without the hassle of cryptocurrency conversion.
Simple operation: The registration and card opening process is intuitive and can be completed in a few minutes.
Stable and reliable: Developed by a team with six years of overseas Fintech experience, it has a high payment success rate and has been validated by the market.
Wide range of applicable scenarios: It supports not only OpenAI API recharges and ChatGPT Plus subscriptions but also various overseas services like Claude, Midjourney, GitHub Copilot, etc.

Moreover, by registering WildCard with the invitation code "LEIXUE," you can enjoy card opening discounts, further enhancing cost-effectiveness.

How to Recharge OpenAI API through WildCard?#

Next, I will guide you through the entire process of recharging OpenAI API in a natural and smooth manner. Assume you already have an OpenAI account (if not, you can register on the official website first), let's start with WildCard.

Step 1: Register a WildCard Account#

Open the WildCard Official Website.
Click the "Login/Register" button in the upper right corner, and after the login window pops up, select "Register."
Enter your phone number (mainland users default to +86, Hong Kong users select +852), obtain the verification code, fill it in, and then click "Submit Registration."
Tip: Enter the invitation code "LEIXUE" during registration to enjoy a discount on the card opening fee.

After registration, you will enter the WildCard backend page. This acts as a payment hub where you can manage your virtual cards and balance.

Step 2: Open a Card and Recharge#

The card opening fee for WildCard is very transparent. Currently (March 2025), a 2-year card costs $11.99, and a 3-year card costs $16.99, with an additional $1 discount using the invitation code "LEIXUE." Compared to other virtual cards that often require monthly fees, WildCard's one-time payment model is clearly more cost-effective.

Find "My Cards" in the left menu bar and click to enter the card opening page.
Choose the duration you need (it is recommended to select 2 or 3 years for long-term use), and enter the invitation code "LEIXUE."
Click "Pay" and complete the payment via Alipay or WeChat scan.
After successful payment, fill in your name and other information as prompted, and the virtual card will be opened.

After opening the card, you need to recharge it to use it. WildCard supports Alipay and WeChat payments, with a minimum recharge amount of $5 and a fee of 3.5%. Considering that OpenAI API may deduct a $5 pre-authorization during the first binding, it is recommended to recharge at least $25 initially to avoid insufficient balance.

Step 3: Bind OpenAI and Recharge API#

Log in to your OpenAI account and go to the "Billing" page.
Click "Add payment method" and select the credit card option.
Copy your virtual card number, expiration date, and CVV code from the WildCard backend and fill them in the OpenAI payment information.
After saving, OpenAI will perform a small pre-authorization (usually $1-5) to confirm the card's validity.
Once successfully bound, click "Add to balance," enter the amount you wish to recharge, such as $10 or $50, and confirm the payment.

The entire process usually takes just a few minutes, and after successful payment, your OpenAI API balance will be updated immediately, ready for use.

If you also want to subscribe to ChatGPT Plus ($20 per month), the steps are similar to recharging the API. After binding the WildCard virtual card:

Go to the "Subscription" page of your OpenAI account.
Select "Upgrade to Plus" and confirm that the payment method is the WildCard card you just bound.
Click subscribe, and the system will automatically deduct $20. After successful subscription, you can enjoy the enhanced features of Plus.

It is worth mentioning that I was impressed by the payment stability of WildCard. I had tried to subscribe using other virtual cards, but they were rejected frequently, causing me a lot of frustration. However, with WildCard, it was successful on the first try, and I have not encountered any issues since.

More Uses of WildCard#

In addition to OpenAI, WildCard can help you unlock more overseas services. For example:

Content Creation: Subscribe to Midjourney for high-quality image generation or use Adobe tools to enhance design efficiency.
Development Needs: Recharge GitHub Copilot to improve coding efficiency; bind Claude API to explore more AI models.
Daily Use: Supports X/Twitter Premium, PayPal, Google Play, etc., covering various aspects of life and work.

Currently, WildCard does not support a few services like Apple Pay and Netflix, but the official team will continuously update the supported range based on user demand, so it is worth keeping an eye on.

Notes and Practical Suggestions#

Although WildCard is very convenient to use, here are a few points to keep in mind to ensure smooth recharging and subscriptions:

Network Environment: It is recommended to use a stable home network IP during payment to avoid being flagged due to multiple users on proxy nodes.
Balance Management: Regularly check the balance on your WildCard card to avoid subscription interruptions due to insufficient funds.
Customer Support: If you encounter any issues, you can contact WildCard customer service through the official website, and they respond quickly.

Additionally, if you are not averse to recharging with USDT, options like Dupay or VCard are also alternatives, but their complexity and stability are not as good as WildCard, making them suitable for users with cryptocurrency experience.

Conclusion: The Best Choice for Recharging OpenAI in 2025#

As of March 2025, WildCard is undoubtedly a subscription tool tailored for domestic users seeking overseas services. It solves the cross-border payment problem with the convenience of Alipay and WeChat payments; its stability and security have earned the trust of many users. Whether recharging OpenAI API or subscribing to ChatGPT Plus, WildCard allows you to get started easily, focusing on the creativity brought by AI rather than the cumbersome payment details.
