What travels ## An email, a key, a request Three facts about the account, from the privacy page. ### The account An email address, each top-up with its amount and the payment’s own reference, and the keys you create. No name, no ID, no phone number. ### The request Your key, the model id and the content. One usage record is kept per request: request id, model, token counts and the charge. Request and response bodies are not stored. ### The payment USDT, USDC, BTC, ETH, SOL to the address the checkout shows; the balance credits in USD when the network confirms. No card on file for crypto top-ups.
