## Named positioning — GET `/v1/kols/positioning`

How KOLs, traders and funds are positioned on each perp: long vs short, entry, PnL, liquidation risk and 1 h / 24 h flows.

Layers: HyperCore. Not on Elysium or HyperEVM: positions are HyperCore perps; on the EVM layers the named wallets swap and hold tokens: the KOL leaderboard and moves of {layer}.
