x402 Expert: We are researching how to integrate x402 into Venice. According to our research, x402 does not support any billing mechanisms where the cost cannot be predetermined. Therefore, for LLM (the cost is not determined until the end), users will need to pay a certain amount in x402, and may overpay, after which we can either refund the difference once the final cost is determined, or keep the difference in their account.
Is this really the case? Does x402 not support pay-as-you-go streaming payment methods?
