What it does
Use for one call answering 'where is retail attention right now': a deterministic 0–100 attention score per ticker blending Reddit finance-community and 4chan /biz/ mention shares (24h window), with momentum, cross-platform confirmation, breadth & concentration (HHI), and Fear & Greed context. Transparent — every row carries its raw per-platform inputs. From x402stock
