Pass the pay-to address a service asked you to pay; returns whether Verantis knows the wallet, its EARNED reputation tier, and human-readable reasons. A wallet IS a settlement rail, so the reply names the rail it settles on ('rail': chain + protocols), its host, on-chain buyer retention (distinct buyers, repeat rate, distribution), and the host's OTHER rails ('also_settles_on'). If 'shared_wallet' is true the address fronts many services (a relay/treasury) so the reputation reflects the pool, not one service — treat with care. An unknown or low-reputation recipient is a reason to pause.",
