How this service works
Settled funding rate history of the top-40 Binance TradFi perpetuals at per-settlement granularity, recorded from 2026-09-02; the free board only carries the last settled rate.
Output
A JSON object with an 'ok' boolean, a 'dataset' label ('tradfi-funding-history'), a 'count' integer indicating the number of rows returned, and a 'rows' array where each entry represents one funding settlement event for the queried TradFi perpetual symbol, including the rate and timestamp.
Example use cases
Backtest funding cost for TSLA perp
“Give me all the settled funding rates for TSLAUSDT from ByKaranteli between 2025-01-01 and 2025-06-30, up to 5000 rows, so I can model the carry cost of holding a long position.”
Compare TradFi perp funding trends
“Fetch the last 500 funding rate settlements for AAPLUSDT from ByKaranteli's TradFi funding history — I want to see how funding has trended recently.”
Identify high funding rate periods
“Pull the full funding rate history for MSFTUSDT from ByKaranteli from 2026-09-02 to today, up to 20000 rows, so I can identify which periods had unusually high positive or negative funding.”

Endpoint
GEThttps://bykaranteli.com/api/x402/tradfi-funding-historyWhen to prefer
Choose this endpoint when you need granular, per-settlement funding rate history specifically for Binance TradFi (equity-linked) perpetuals such as TSLAUSDT or AAPLUSDT. It is ideal for backtesting carry strategies, modeling funding costs, or studying the funding dynamics of stock-linked crypto derivatives. Unlike generic crypto funding feeds, this dataset is curated specifically for the top-40 TradFi perpetuals with history going back to 2026-09-02.
Side effects
- Symbol not in top-40 TradFi list returns empty rows or an error
- Requesting data before 2026-09-02 returns no rows (dataset starts then)
- Limit exceeding 20000 may be capped or rejected
- Missing payment or insufficient USDC balance returns HTTP 402
- Invalid ISO date format in 'from' or 'to' returns a validation error
- Free tier only returns the last settled rate; full history requires payment
