CEX Funding Rate Aggregator

Aggregate perpetual swap funding rates across Binance, Bybit, and OKX in one call. Spot funding extremes, cross-venue spreads, and carry-trade signals. No API key required.

---

What It Does

Pulls live funding rates for USDT perpetual swaps from the three largest crypto derivatives venues and normalizes them to annualized percentages (APR). Use it to:

• Find symbols with extreme funding (over-leveraged longs or shorts)
• Detect cross-venue funding spreads (cash-and-carry arbitrage)
• Time market-tops/bottoms — extreme positive funding often precedes squeezes
• Get Telegram alerts when any symbol's |funding APR| crosses your threshold

Why Funding Rates Matter

Perpetual futures don't expire — instead they use funding to anchor the perp price to the spot index. Every 8 hours, one side pays the other:

• Positive funding → longs pay shorts → market is long-skewed (often bullish-positioned, sometimes overextended)
• Negative funding → shorts pay longs → market is short-skewed (often fear-driven, contrarian buy signals)

Extreme funding rates (|APR| > 50%) often signal late-stage trends or capitulation. Cross-venue spreads create cash-and-carry opportunities — long the cheaper-funded venue, short the more expensive one, collect the spread.
