Use when a Base address just paid you and you want to know what it is before you
Use when a Base address just paid you and you want to know what it is before you act on it. Returns its public x402 payment footprint in the window (payments, distinct recipients, cadence, native activity, what this shop has seen of it) and a class with evidence and confidence — disclosed_scout, scheduled_verifier, catalogue_sweep, paying_index, repeat_buyer, single_touch — plus the rule for reading it. Not an identity claim. Free doors: /api/v1/payer-profile/example and /classes.
