1. Registering for an xAI Account and Claiming the $150 Free Credit#
1. Visit the xAI Official Website and Register#
First, open your browser and visit the xAI official website. Click the "Sign Up" button in the upper right corner to enter the registration page. You will need to provide a valid email address and set a secure password. Domestic users are advised to use internationally recognized email services (such as Gmail or Outlook) to ensure smooth receipt of verification codes.
After completing email verification, log in to your xAI account, and you will enter the user dashboard. xAI currently offers new users a $150 free credit to experience Grok 3 or API calls.

2. Notes on Claiming Free Credit#

- Invitation Code: Some events may provide invitation codes for additional discounts; it is advisable to follow xAI's official social media (such as X platform) for the latest information.
- Credit Usage: The $150 credit can be used for Grok 3's advanced features (such as DeepSearch mode) or API calls, suitable for first-time experiences.
2. xAI API Card Binding and Recharge Tutorial#
For developers who need to use the xAI API long-term, binding a payment method and recharging is an essential step. Due to payment restrictions, traditional bank cards (such as UnionPay) often cannot be directly bound for domestic users. It is recommended to use WildCard, a subscription card designed for domestic users to access overseas software.
1. Why Choose WildCard?#
Compared to other virtual cards (such as Dupay, VCard, PokePay, WasabiCard, LocalCard), WildCard has the following advantages:

After logging in, go to the "My Cards" page, select the card duration (1 year or 2 years), and complete the payment by scanning the QR code with Alipay or WeChat. It is recommended to recharge $25 for the first time to cover a possible $5 pre-authorization fee and subsequent API costs.

Step 3: Bind WildCard to xAI#
On the xAI official website's "Billing" page, click "Add Payment Method," and enter the virtual card number, expiration date, and CVV code provided by WildCard. After successful binding, xAI will perform a small pre-authorization (usually $1-$5) to ensure sufficient balance for verification.
