What it returns
Funding rates for every perpetual futures market on Hyperliquid and dYdX in one call, on one scale.
Snapshot**: current funding rate, funding interval, the rate normalized to 8 hours, **annualized %**, next funding time, mark and index price, **open interest in USD** and 24h volume, for every market. Spreads**: for each coin listed on both venues, the venue with the lower and higher funding, the annualized gap, and each venue's rate: the basis for funding-rate arbitrage screens. History**: settled funding rates over up to a year for any coin. Rates are compared on the same footing: hourly rates show up as 8-hour and annualized %.
