Questions
How is this different from the official APIs?
The same models behind one key and one bill: prices in US dollars, top-ups with Alipay or USDT, and OpenAI- and Anthropic-compatible endpoints for the tools you already use.
How am I charged?
Per token, in US dollars, from a prepaid balance. Input, output, cache-read and cache-write tokens are each charged at the model's listed price. Failed requests are not charged, and every charge appears in your usage log.Billing and top-ups →
Is there free credit?
Free trial credit when you sign up. It is added to your USD balance and spent at normal model prices. Models marked Free cost $0 per token but, like every request, need a balance above $0.Trial credit and free models →
How can I pay?
Top up on the payment page in the console. The methods available are those shown there, for example Alipay and USDT (TRC20, ERC20, BEP20). Your balance is always in US dollars, and any fee is shown before you pay.
Are my prompts stored or used for training?
Prompts and outputs of successful requests are passed to the model provider and not kept after delivery. Bodies of failed requests are kept for up to 30 days, with credentials removed, for troubleshooting. Prompts are never used for training. Providers may keep data under their own terms.Privacy policy →
