How this service works
Crypto perpetual-futures snapshot for a symbol in ONE call (Binance USD-M, keyless): current funding rate and the next funding time, mark and index price, open interest (contracts and USD), 24h price change/high/low/volume, and the top-trader long/short account ratio. For funding arbitrage, leverage/positioning reads, and a derivatives view an onchain-only feed cannot give. Cached 30s.
Output
A JSON object containing: the perpetual symbol, funding rate, annualized funding rate percentage, next funding timestamp (Unix ms), mark price, index price, open interest in contracts and USD, 24h high/low/volume and price change percent, and the top-trader long/short account ratio. Data is sourced from Binance USD-M and cached for 30 seconds.
Example use cases
Funding arbitrage opportunity scan
“Check the current funding rate and annualized funding rate for ETH perp — I want to know if it's worth running a cash-and-carry trade right now.”
Derivatives positioning dashboard
“Pull me a full perp snapshot for SOL — I need the open interest in USD, the long/short ratio, and the 24h volume to gauge how traders are positioned.”
Next funding time alert setup
“When is the next funding time for BTC perpetual futures, and what is the current funding rate? I want to decide whether to hold my position through it.”
Technical details
Endpoint
GEThttps://chain.cyberwarex.com/derivatives?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a one-call, aggregated derivatives view for a crypto asset — especially when you need funding rate, open interest, and long/short ratio together without assembling multiple Binance API calls. Ideal for funding arbitrage decisions, leverage/positioning reads, or when onchain-only data sources lack derivatives coverage.
Side effects
- Unknown or unsupported symbol returns null fields or an error
- Symbol not available on Binance USD-M returns empty or null data
- Network/cache timeout may return stale data beyond the 30s cache window
- Malformed symbol input (e.g. wrong format) may return an error response
- Payment failure (x402) if USDC balance is insufficient
