Settle a network-MEMBER (e.g. RRG) purchase after you have sent the USDC that buy_product asked for. This is the member two-step: buy_product returns a pay-to address and amount, you transfer USDC on Base, then call this with the tx hash to mint, pay out, and get your download. For physical products include the shipping block and buyer_email. VIA-native purchases do NOT use this: they settle at the /api/x402/purchase endpoint that buy_product returns.
