How this service works
Settled funding rate history of every Binance USDT-M perpetual, crypto and TradFi, one row per settlement since 2026-05-31, each with its funding time, kept current hourly from Binance's settlement list (a delisted contract Binance still lists there keeps its placeholder rate): the series behind carry and basis work. The free metric-daily download carries one daily BTC funding aggregate.
Output
Returns a JSON object with ok=true, a dataset label of 'funding-history', a count of returned rows, and a rows array containing settled funding rate records per symbol and venue — each record includes timestamp, symbol, exchange, and funding rate value.
Example use cases
Carry trade performance analysis
“Fetch the funding rate history for ETHUSDT on Bybit for all of 2023 — up to 500 rows — so I can calculate the average annualized carry and see how it trended over the year.”
Cross-exchange funding rate arbitrage
“Get me the funding rate history for SOLUSDT on both Binance and OKX from October 1 to December 31 2023, so I can compare which venue paid higher funding and identify arbitrage windows.”
Basis trading backtesting
“I need the last 90 days of settled funding rates for BTCUSDT across all available exchanges — limit to 500 rows — to backtest a cash-and-carry basis strategy.”
