Use this endpoint when you need historical or current open interest data specifically for futures instruments on major crypto exchanges like Binance, OKX, Deribit, or Bybit. Prefer this over WebSocket channels when you need historical time-series data rather than real-time streaming. Ideal for backtesting, charting, or analyzing open interest trends across specific instruments and timeframes.
