On Base or Polygon you need a little USDC and no gas token: your wallet signs an authorisation for the exact amount and the payment service submits it. Phantom currently adds instructions to Solana payments that the payment service rejects, so use Base unless your Solana wallet works. Payments for successful calls are final. See the terms.
