  "description": "Institutional 13F ownership and flow made agent-callable. One x402 call takes a stock ticker and returns a flow read (ACCUMULATION / NEUTRAL / DISTRIBUTION) from how the top institutional holders changed their positions quarter-over-quarter, plus total institutional ownership percent and count, insider ownership, and the top holders each tagged added / trimmed / held / new. The 'what are the big funds doing' read a trading or research agent needs, served pay-per-call. $0.05 in USDC on Base via x402. Source: yfinance aggregation of SEC 13F filings (free/public). NOTE: 13F is filed quarterly, ~45 days after quarter-end, so this is last-quarter positioning (lagged), and it covers long US equity positions only (no shorts or derivatives). Companion to EquityScope, AnalystEdge, InsiderFlow and CapitolFlow (the smart-money cluster).",
