- 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://www.lithovas.com/api/chat` with `model: "chat/gemini-3-pro"`.
When this is better than Google official billing
Choose 97AI.PRO when you do not have a US or EU credit card, when Google's direct billing is not available in your region, or when you want one wallet for Gemini 3 Pro plus chat, image, video, audio, and embedding models. Official billing is still best when your company requires a direct vendor contract.
