Credits and API key

Pay by the print, in USDG.

One credit is one dollar of model use. Top up by sending USDG on Robinhood Chain to the house treasury; your balance is read from the chain. Your API key is a signature from your wallet: it costs no gas, cannot move funds, and stays in this browser tab.

1 · Sign your key

Your wallet signs one fixed line. The server only reads your address back from the signature.
