copy.leaderboard
1 crread-onlyRank the institutional managers (13F funds) worth copying. Each row is a followable actor — name, manager, book size (AUM), holdings count, latest reported quarter, follower count, the slug (for copy.target.get), and CIK (to follow via watchlist / pull via fund.holdings). Price-derived copy-return fields are withheld unless the price-source policy and freshness gate are green. The agent-native 'who should I copy?' entry point. Sort by book size, recent activity, follower count, or gated track record. Public-domain SEC EDGAR 13F data.
