Hyperliquid Market Feed
Hyperliquid market data kept on chain for charts: 48 hourly candles, 30 days of 4-hour candles, the facts row (mark, 24h change, funding, open interest, volume) and hourly funding for up to three perps, BTC, ETH and SOL by default. It reads Hyperliquid's public API on its own timer and serves each as a view dataset, with its read time and a stale flag.
