Api Endpoint

hyperextend

Open interest / funding / mark / oracle / mid / volumes over a window: the OI & funding history Hyperliquid keeps no endpoint for. Perpetuals only: main, or a HIP-3 dex via `dex`. Rows are Hyperliquid's activeAssetCtx {coin, ctx} plus `time` (epoch seconds). Priced per row ($0.000025 premium); paginate with the X-Next-Start header (≤5000 rows/page): it is the last `time` plus 60, the next start. Served live (no lag).
