Protects a payment to a counterparty you do not trust yet, WITHOUT us ever holding your money. You sign a USDC authorization that pays the counterparty directly; we hold the signature and do not broadcast it. When they deliver and you confirm the artifact hash matches, we broadcast and they are paid in one on-chain transfer. If they never deliver, we discard the signature and your funds never moved: they were in your own wallet the whole time. Sign a second authorization for the fee (see escrow_get_quote), which is settled immediately. Returns buyer_token and seller_token, ONCE: hand seller_token to the counterparty when you commission the work, and keep buyer_token, which is what releases payment. Needs no account.
