With the rapid development of artificial intelligence technology, OpenAI's API interface has become the preferred tool for developers, researchers, and businesses to build intelligent applications. In particular, the latest o3 model (assumed to be the code name for OpenAI's next-generation model) has attracted significant attention due to its powerful language understanding and generation capabilities. However, the application process for o3 interface permissions and API balance recharge may present certain barriers for domestic users, especially regarding payment restrictions. This article will detail the steps for applying for o3 interface permissions and recommend the most convenient API balance recharge method for domestic users—WildCard, helping you quickly get started with OpenAI's powerful features.

1. Complete Process for Applying for OpenAI o3 Interface Permissions#
The application for OpenAI's API interface permissions needs to be completed through the official platform. As a high-performance model, the o3 model may have stricter review mechanisms. Here are the detailed steps for applying for permissions:
1. Register an OpenAI Account#
- Visit the OpenAI official website (https://platform.openai.com) and click "Sign Up" to create an account.
- Register using an email or Google account; it is recommended to choose a commonly used email to receive review notifications.
- Domestic users may need to use a VPN to ensure smooth access.
2. Complete Account Information#
- After logging in, go to the "Settings" page to complete personal information, including name, company name (optional), and contact information.
- On the "Billing" page, bind a payment method. OpenAI requires binding an international credit card (such as Visa or MasterCard), but domestic bank cards may not be directly usable due to restrictions. At this point, it is recommended to use WildCard, which is designed for domestic users and supports recharge via Alipay or WeChat, making it simple and stable.
3. Submit API Permission Application#
- Go to the "API" page and click "Request Access" or the relevant application entry.
- Fill out the application form, which usually includes:
- Usage Scenario: Describe in detail how you plan to use the o3 interface (e.g., developing a chatbot, content generation tool, or data analysis system).
- Technical Capability: Explain your development experience or your team's technical background.
- Compliance Commitment: Confirm compliance with OpenAI's usage policies (such as data privacy and content security).
- If applying for the o3 model, OpenAI may request additional information, such as project scale or expected API call volume.
4. Wait for Review#
- After submitting the application, OpenAI typically responds within a few days to two weeks. During the review period, keep your email accessible and respond promptly to any requests for supplementary materials.
- If the application is rejected, you can optimize the application content based on feedback and resubmit.
5. Obtain API Key#
- Once approved, go to the "API Keys" page to generate a key. Each key corresponds to a project, so be sure to save it properly and do not disclose it.
- Use the key to call the o3 interface for development, and it is recommended to refer to OpenAI's official documentation for a quick start.
2. OpenAI API Balance Recharge: Pain Points and Solutions for Domestic Users#
OpenAI API adopts a pay-per-use billing model, and developers need to pre-recharge their balance to ensure uninterrupted interface calls. However, domestic users often face the following issues when recharging:
- Payment Restrictions: OpenAI only supports international credit card payments, and domestic UnionPay cards or some dual-currency cards may be rejected due to bank risk control.
- Complex Process: Some virtual card platforms (such as Dupay, VCard, PokePay) require recharging through cryptocurrencies like USDT, which is cumbersome and carries exchange rate fluctuation risks.
- Stability Issues: Some virtual cards may be intercepted by OpenAI due to unstable payment channels, leading to recharge failures.
To address these pain points, WildCard offers the most suitable solution for domestic users. Here are the core advantages of WildCard:
1. Convenient Domestic Payment Methods#
WildCard supports direct recharge via Alipay and WeChat, eliminating the need to purchase cryptocurrencies or engage in complex foreign exchange operations.
