1. Why Use OpenAI API?#

OpenAI API provides powerful natural language processing (NLP) capabilities, helping developers easily integrate AI features. The main application scenarios include:

Intelligent Q&A: Integrating AI for automatic Q&A in websites, applications, or social platforms.
Content Creation: Generating articles, marketing copy, social media posts, etc.
Code Generation: Assisting programmers in writing code to improve development efficiency.
Language Translation: Supporting automatic translation in multiple languages.
Text Summarization: Quickly summarizing lengthy content to enhance reading efficiency.

However, to use the OpenAI API, the first challenge to address is how to successfully register and recharge an OpenAI account, which is quite a challenge for domestic users.

2. Common Payment Issues for Domestic Users#

Since OpenAI's official payment channels mainly rely on international credit cards (Visa, MasterCard, American Express), this poses many difficulties for domestic users, including:

Domestic Credit Card Payment Failures: Most Visa and MasterCard credit cards issued by domestic banks cannot pass OpenAI's payment verification.
PayPal Binding Failures: Binding a PayPal account to a domestic bank card may encounter payment restrictions or transaction failures.
Frozen Recharge Amounts: Some users may find that even after successful payment, their OpenAI accounts cannot be used normally due to risk control issues.

Therefore, the most reliable method is to use virtual credit cards specifically provided for domestic users, such as WildCard, to solve the OpenAI API recharge problem.

3. Using WildCard to Recharge OpenAI API#

WildCard is a virtual credit card service provided by a domestic company, specifically optimized for OpenAI, ChatGPT, Claude, and other overseas software subscriptions. It supports domestic users to recharge using WeChat or Alipay, solving the international credit card payment issue.

1. Register a WildCard Account#

First, visit the WildCard official website:

Click "Register" on the official website, use a domestic phone number to complete account creation, and verify your identity through an SMS verification code.

2. Apply for a WildCard Virtual Credit Card#

After registration, enter the WildCard backend and follow these steps to apply for a virtual card:

Select the "Open Card" option and fill in the necessary information.
Choose a suitable card opening package (generally recommended to choose 2 years or 3 years).
Pay the card opening fee using WeChat or Alipay.

Once the card opening is completed, you will receive a Visa virtual credit card that can be used to pay for OpenAI API subscription fees.

3. Recharge WildCard Balance#

Since WildCard is essentially a prepaid virtual credit card, you need to recharge the balance before it can be used for consumption. It is recommended to recharge $25 for the first time to ensure successful payment.

Recharge process:

Enter the WildCard account backend and select "Recharge."
Choose a payment method (Alipay, WeChat, etc.).
After successful recharge, you can see the balance update on the virtual credit card information page.

4. Use WildCard to Bind OpenAI API Account#

Visit the OpenAI API Official Website to register or log in to your account.
On the Billing page, click "Add a payment method."
Enter the virtual credit card information provided by WildCard, including card number, expiration date, and security code (CVV).
After verification, the system will automatically deduct $5 for account verification (this amount will be refunded later).
Once successfully bound, you can recharge your balance on the OpenAI API platform and start calling GPT-4o and other API services.

4. How to Verify if the API is Usable?#

After successful payment, you can perform the following tests to ensure that the OpenAI API account can be used normally:

Check API Balance: View the account balance on the Billing page of the OpenAI API official website to see if it has been credited.

Test API Call: Open a terminal or code editor and run the following Python code for API testing:

import openai

openai.api_key = "your API Key"

response = openai.ChatCompletion.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "Hello, how to use OpenAI API?"}]
)

print(response["choices"][0]["message"]["content"])

Check for Access Restrictions: Some IPs may not be able to access the OpenAI API, so it is recommended to test using overseas networks or proxies.
