How to read this: the grade estimates how much of this endpoint's claimed call volume is supported by organic multi-party on-chain demand. It is a statistical opinion derived from public data — not an accusation of wrongdoing. Full signal definitions, the n/v rule, and limitations are in the methodology. Operators can dispute or annotate via GitHub issues.
