payable

Hyperliquid vaults, two modes in one route: pass `vault` (an address) for a single vault overview — name, leader, TVL, APR, age, max drawdown, pnl trend and a deterministic 0-100 quality score; or omit it for a ranked discovery list of the top open vaults by `sort` (tvl or apr). public on-chain data, not financial advice.

We sent a real GET request to this endpoint and it answered 402 with payment requirements we could parse.
