Onchain facts for a Base ERC20 address: ERC20 shape, honeypot-style selectors and an ungraded adminPowers profile (proxy, owner, mint, blacklist, pause) with raw evidence per check. No DEX data, grade is n/a. No LLM.
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.
