Get Daily Hyperliquid

GET/v1/cryptodata/daily/hyperliquid

Hyperliquid perpetuals: prices, funding rates, and open interest (~230 assets). Each entry in ``funding_oi`` contains both raw and derived fields: - ``funding_rate`` — Hyperliquid's own funding rate, per HL funding interval (1h on HL by default). Negative values indicate shorts paying longs. This is **Hyperliquid-specific**; cross-exchange averaged funding lives in ``/market-health`` and ``/market-intelligence/funding-rates``. - ``open_interest`` — **in base-coin units** (number of contracts), mirroring the Hyperliquid API. For BTC this might be ``28846.42`` meaning ~28.8K BTC. Use this when comparing across exchanges that quote OI in the same units. - ``open_interest_usd`` — derived notional in USD = ``open_interest * mark_price``. Use this for "is this market large enough to trade?" thresholds. - ``mark_price`` / ``oracle_price`` — both USD. - ``day_ntl_vlm`` — 24h notional volume, **already USD-denominated**. - ``premium`` — Hyperliquid's own ``premium`` context field (mark vs oracle premium), passed through unchanged. - ``as_of`` — ms timestamp of the ``metaAndAssetCtxs`` snapshot the row came from (one call covers the whole universe, so every row shares it). Top level: ``generated_at`` (ms, when this payload was assembled), ``prices_as_of`` / ``funding_oi_as_of`` (ms fetch instants of the two HL snapshots) and ``coverage`` = ``{universe_total, delisted_excluded, rows}`` — HL keeps delisted perps in its universe with a mark but no OI/funding, and they are excluded here, which is why ``rows`` (~177) is below the ~232 universe. Refresh cadence: 1 minute. Thinly-traded perps may emit ``open_interest = 0`` legitimately when no positions are open.
