3-step setup without a card
- Create a 97AI.PRO account with email and password.
- Open billing and choose USDC on Arbitrum, Alipay, or WeChat Pay. The minimum top-up is $5.
- Use the model page or API endpoint `https://97ai.97claude.com/api/chat` with `model: "chat/grok-4-3"`.
When this is better than xAI official billing
Choose 97AI.PRO when you do not have a US or EU credit card, when xAI's direct billing is not available in your region, or when you want one wallet for Grok 4.3 plus chat, image, video, audio, and embedding models. Official billing is still best when your company requires a direct vendor contract.
