Agent Mercantile

Produce a factual snapshot of current x402 payment authority for one unpaid v2 requirement and one public EVM payer: selected scheme/network/asset/amount/payTo/transfer method, same-block token balance, canonical token-spender allowance when that path applies, and declared recovery-path classification. Does not sign, approve, construct a transaction, judge native gas, or recommend whether to buy.
