OpenAI's API interface has become a popular choice for developers, researchers, and business users. Particularly, the widespread use of ChatGPT Plus and the OpenAI API has led many domestic users to hope to achieve creative development, content generation, or business optimization through these tools. However, due to international payment restrictions and regional policies, domestic users often encounter difficulties when subscribing to ChatGPT Plus or recharging the OpenAI API. This article will detail how domestic users can obtain OpenAI o3 interface permissions, the steps to apply for API access, and recommend a payment solution—WildCard, to help you easily embark on the path of AI development.

Why Choose OpenAI API?#
OpenAI API provides a powerful language model interface, supporting various functions such as text generation, code completion, and data analysis. Compared to the conversational interaction of ChatGPT Plus, the API is more suitable for scenarios that require deep customization, such as:
- Developing Intelligent Applications: Embedding AI into chatbots, content generation tools, or customer service systems.
- Automating Tasks: Achieving batch text processing, translation, or data organization through the API.
- Innovative Experiments: Researchers can use the API for model testing or algorithm optimization.
For domestic users, obtaining API access not only requires registering an OpenAI account but also solving payment issues, as OpenAI requires binding an international credit card (such as Visa or MasterCard) for subscriptions or recharges. This poses a challenge for many users, especially since traditional bank cards may fail due to risk control.
Steps to Apply for OpenAI API Access#
Here are the detailed steps for domestic users to apply for OpenAI API access:
1. Register an OpenAI Account#
Visit the OpenAI official website (https://openai.com), and click “Sign Up” to create an account. Note the following points:
- Use an Overseas Email: It is recommended to use international email services like Gmail or Outlook to avoid verification issues that may arise with domestic emails.
- Use a VPN: Due to network restrictions, you may need to use a VPN or proxy tool to access the official website.
- Phone Number Verification: OpenAI requires binding a phone number, and domestic numbers may be restricted. It is advisable to use a virtual number service or an overseas number.
Once registration is complete, log in to your account to access the OpenAI platform.
2. Apply for API Access#
OpenAI API is not open by default and must be applied for manually:
- After logging in, go to the “API” page (https://platform.openai.com).
- Click “Create API Key” to generate a key, and the system will prompt you to bind a payment method.
- If you are a new user, you may need to fill out a purpose description, such as describing your project or development needs.
- Review usually takes a few hours to a day, and once approved, you can use the API.
Tip: When applying, try to describe your purpose in detail, such as “developing an educational chatbot” or “researching natural language processing,” which can improve your approval rate.
3. Bind Payment Method#
OpenAI API uses a pay-as-you-go billing model, and you need to bind a payment method to pay for usage fees. Domestic users often get stuck at this step due to the lack of international credit cards. Here are the solutions:
- Traditional Bank Cards: Some banks' Visa or MasterCard dual-branded cards may be supported, but the success rate is low and often rejected due to risk control.
- Virtual Credit Cards: It is recommended to use virtual card services specifically designed for domestic users, such as WildCard, which supports Alipay and WeChat recharges, is easy to operate, and stable.
4. Testing and Development#
After obtaining the API key, you can learn how to call it through the official documentation (https://platform.openai.com/docs). It is advisable to start with simple text generation interfaces and gradually explore more complex functions.
Recommended Payment Solution: WildCard#
Among many virtual card services, WildCard is the ideal choice tailored for domestic users. Compared to other virtual cards (such as Dupay, VCard, PokePay, WasabiCard, LocalCard), WildCard has the following advantages:
1. Convenient Recharge Methods#
WildCard supports direct recharges via Alipay and WeChat, eliminating the need to purchase USDT or deal with complex cryptocurrency transactions. Users only need to scan a QR code to complete the recharge, making it very easy for beginners.
2. Stability and Security#
WildCard's payment channels are optimized to effectively avoid the risk control of the OpenAI payment system, ensuring a high success rate for subscribing to ChatGPT Plus or recharging the API. Compared to virtual cards relying on cryptocurrency, WildCard is more stable and reduces payment failure issues.
3. Wide Range of Applicable Scenarios#
In addition to OpenAI, WildCard also supports subscriptions to other overseas services, such as Claude, Midjourney, Google Play, Apple Store, etc., making it a multifunctional payment tool.
4. Promotional Activities#
By registering through the WildCard Official Website and using the invitation code “LEIXUE,” new users can enjoy a card opening discount. The current pricing is $11.99 for one year or $16.99 for two years, and using the invitation code can reduce it by another $1, offering great value.
Recharge Suggestion: For the first recharge, it is recommended to recharge $25 to cover OpenAI's $5 pre-authorization fee and the $20 subscription fee for ChatGPT Plus, avoiding insufficient balance.
Comparison with Other Virtual Cards#
Although there are other virtual cards available on the market, they are slightly inferior to WildCard in terms of convenience and stability:
- Dupay: Requires USDT recharge, complicated operations, and occasional maintenance may affect usage.
- VCard: Suitable for cryptocurrency users but requires KYC verification, which is cumbersome.
- PokePay: Supports various cryptocurrencies, but non-USD spending incurs additional conversion fees.
- WasabiCard and LocalCard: Also rely on USDT, with stability not as good as WildCard.
For domestic users looking to get started quickly, WildCard's Alipay/WeChat recharge and no KYC verification requirements are undoubtedly more attractive.
Notes and Practical Suggestions#
- Network Environment: Avoid using public proxy IPs during payment, as it may trigger risk control. It is recommended to use a home network or a dedicated node.
- Balance Management: Regularly check the WildCard balance to ensure smooth API usage or subscription renewals.
- API Cost Control: OpenAI API charges based on usage, so it is advisable to set budget limits to avoid overspending.
- Community Support: Join the OpenAI developer community or domestic AI forums to get the latest tutorials and experience sharing.
