How this service works
Interactive Bitcoin 4-year halving cycle chart on a polar disc. Live price, 200W MA, Mayer Multiple, RSI, MACD, Pi Cycle and optional paid cycle projections.
Output
A JSON object with a 'rows' array where each entry contains: symbol, markPrice, indexPrice, openInterest (in base coins), lastFundingRate (decimal), fundingRatePct (percent), longAccountPct, longShortRatio, and nextFundingTime (epoch ms). Also includes a count of returned symbols and a generatedAt timestamp.
Example use cases
Crypto funding rate arbitrage monitor
“Give me the current funding rates and long/short ratios for BTCUSDT, ETHUSDT, SOLUSDT, BNBUSDT, and XRPUSDT on Binance futures — I want to spot any extreme funding that might signal a trade.”
Sentiment check before entering a position
“Before I go long on Bitcoin, can you check the current BTC perpetual futures data — specifically the long account percentage, long/short ratio, and funding rate — to see if the market is already too crowded on the long side?”
Top 10 futures market overview
“Fetch the full derivatives snapshot for the top 10 Binance USDT-margined futures symbols — give me mark prices, open interest, and funding rates across the board so I can see the overall market state.”
Technical details
Endpoint
GEThttps://4yearcycle.com/x402/derivativesWhen to prefer
Use this endpoint when you need real-time Binance perpetual futures market data — funding rates, open interest, and long/short sentiment — for up to 25 crypto pairs in a single call. Prefer it over general price APIs when derivatives-specific signals (funding rate, long/short ratio) are needed for trading decisions or market sentiment analysis.
Side effects
- Invalid symbol format (must match ^[A-Z0-9]+(,[A-Z0-9]+)*$) returns a validation error
- Requesting more than 25 symbols exceeds the maximum and may be rejected
- Binance API lookup failure may cause openInterest or longShortRatio fields to return null
- Payment failure or insufficient USDC balance results in 402 error
- Symbol not available on Binance USDT-margined futures returns empty or error row
