1. Understanding xAI Grok-3 and Its API Credits#

Grok-3 is an advanced AI model developed by xAI, supporting text generation, image understanding, and complex task reasoning, widely used in content creation, data analysis, and application development. xAI provides an API interface, allowing developers to implement customized features by calling Grok-3. To attract new users, xAI has currently launched a benefit: new registered users can receive a $150 API trial credit for free, allowing them to experience the powerful features of Grok-3 without additional payment.

However, domestic users often encounter obstacles when accessing overseas services due to limited payment channels. Traditional UnionPay cards or some Visa/MasterCard may fail to complete payments due to regional restrictions or risk control strategies. In this case, WildCard becomes the best choice for domestic users. It supports top-ups via Alipay and WeChat, eliminating the need for complicated cryptocurrency (like USDT) operations. Compared to Dupay, VCard, PokePay, WasabiCard, or LocalCard, WildCard offers a simpler payment process with better stability and security.

2. Steps to Obtain $150 API Credits for Free#

1. Register for an xAI Account#

Visit the xAI official website (https://x.ai), click the registration button, and fill in basic information such as email and password. Domestic users are advised to use internationally recognized email services (like Gmail or Outlook) to ensure they receive verification emails. After completing registration, log in to your account to access the API management page.

2. Apply for API Trial Credits#

On the API page of the xAI official website, find the "Free Trial" or "Get Started" option. Fill in simple developer information (such as usage scenarios or project descriptions) as prompted. After submitting the application, xAI typically reviews and approves it within 1-3 business days, automatically adding the $150 trial credit to your account.

Tip: When applying, clearly describe your usage needs, such as "developing an AI chatbot" or "conducting data analysis," as this helps improve the approval rate.

3. Configure WildCard for Payment Verification#

Although the trial credit is free, xAI may require binding a payment method to verify the account. Domestic users can resolve this issue through WildCard. The specific steps are as follows:

  • Register a WildCard Account: Visit the WildCard official website, register using your mobile number, and enter the invitation code LEIXUE to enjoy a card opening discount (save $1).
  • Card Opening and Top-Up: Choose a 1-year ($11.99) or 2-year ($16.99) plan, and top up via Alipay or WeChat. It is recommended to top up $25 for the first time to cover possible pre-authorization fees.
  • Bind the Card: In the payment settings of your xAI account, enter the virtual card information provided by WildCard to complete the verification.

The advantage of WildCard is that it does not require KYC certification, has a low operational threshold, and the payment channels are optimized to effectively avoid risk control interceptions from overseas platforms like OpenAI. Compared to Dupay or VCard, which require USDT top-ups, WildCard's Alipay/WeChat top-up method is more user-friendly for domestic users.

3. Suggestions and Precautions for Using Grok-3#

1. Optimize API Calls#

The $150 trial credit is sufficient to support thousands of API calls, but to extend usage time, it is recommended to optimize request parameters. For example, set a reasonable max_tokens value to avoid generating lengthy responses; batch processing tasks can also effectively reduce costs.

2. Choose an Appropriate Network Environment#

Domestic users may need a stable overseas network environment when accessing xAI services. WildCard provides support for overseas home networks, which can reduce barriers during the payment and registration process. If using a proxy, it is advisable to choose a node with fewer users to avoid triggering risk control due to shared IP addresses.

3. Subscribe to SuperGrok or Continue Using the API#

Once the trial credits are exhausted, you can choose to subscribe to the SuperGrok plan for a higher usage quota or continue to pay as you go through the API. For more details, visit the xAI official website. Regardless of which option you choose, WildCard can provide stable payment support.

4. Why Choose WildCard?#

Compared to other virtual cards (like PokePay or WasabiCard), WildCard's unique advantages include:

  • Convenient Payments: Supports top-ups via Alipay and WeChat, no need to purchase USDT, simple operations, suitable for beginners.
  • High Stability: Payment channels are optimized specifically for domestic users, with a high success rate and low risk of interception.
  • Wide Applicability: In addition to xAI Grok-3, it also supports various overseas services such as ChatGPT Plus, OpenAI API, Claude, Midjourney, etc.
  • Discount Benefits: Register using the invitation code LEIXUE to enjoy a discount on card opening.

5. Conclusion#

For domestic users, obtaining the $150 credit for the xAI Grok-3 API for free is an excellent opportunity to get started. Through WildCard, you can easily complete account verification and subsequent top-ups, enjoying the powerful features of Grok-3. Whether you are a developer, content creator, or AI enthusiast, WildCard can provide you with stable and secure payment support, allowing you to explore the infinite possibilities of the AI world without worries.
