Seller reputation by payTo address: how many endpoints it serves, how many are live, price range, clone-farm and quote-only flags, and on-chain activity on Base (settlements and unique payers over 30 days, last settlement time).
What this grade does and doesn't measure: it scores the paid-request handshake — whether the service returns a spec-valid 402 payment challenge, how fast, and whether its price is honest. We do not pay these endpoints yet, so we do not verify that the paid response returns correct or complete content. Availability is a probe success rate measured hourly, from a single network vantage for this service.
