x402 Listing Watch

Call before trusting or paying a third-party x402 seller: snapshot one listing from a fixed public directory (payapi, cdp, payai, bazaar) by its id/payTo, or pass ?since= to get told whether it changed since you last saw it. Reads public directories only - never a caller-supplied URL - and returns already-public fields (JSON).
