Get Trade Flow Universe
GET/v1/cryptodata/hyperliquid/trade-flow/universe
Taker flow for EVERY Hyperliquid perp over one window, biggest first. ``taker_buy_ratio`` is buy notional over total (0..1; ``null`` for a coin with no fills). ``large_fill_share`` is the share of the window's notional from fills at or above ``large_fill_usd``. ``partial_minutes`` counts the window's minutes our socket did not fully watch — the same for every row, since coverage is per connection, not per coin. Coins with zero fills in the window are omitted. ``as_of`` is the window's end (the last closed minute). Pro Plus.
