Token score by contract address: one 0-100 composite of a Base token market structure from seven weighted factors — USD liquidity, holder concentration and count, 24h volume, market age, pool breadth, price stability. Every sub-score, weight and raw input comes back, so the score can be recomputed. A factor whose data plane is unavailable is reported absent, never filled. Market structure, not a contract-security screen. $0.01 per call.
