How this service works
Funding rate per 8 hours, futures premium, open interest with 1-hour and 24-hour change, and long/short account ratio per coin.
Output
A JSON array of per-coin derivatives metrics including: funding_8h_pct (funding rate per 8 hours as a percentage), futures_premium_pct (spot vs futures premium/discount), open_interest_usd (total open interest in USD), open_interest_change_1h_pct, open_interest_change_24h_pct, and long_short_account_ratio. Also includes a plain-English summary, snapshot timestamp, and data age in seconds. Data is refreshed every minute.
Example use cases
Funding rate arbitrage screening
“Pull the latest 8-hour funding rates and futures premium percentages for BTC, ETH, and SOL — I want to see which coins are most expensive to hold a long position on right now.”
Open interest trend monitoring
“Show me how open interest has changed over the last hour and last 24 hours for the top 50 crypto futures — I'm watching for signs of leverage buildup or unwinding.”
Long/short sentiment check before trade
“Before I enter a position, can you get me the long/short account ratio and current funding rate for ETH and BNB futures?”
Technical details
Endpoint
GEThttps://crypto-market-data.zafermemon87.workers.dev/v1/derivatives?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need derivatives-specific metrics — funding rates, futures premium, open interest, and long/short ratios — rather than spot price data. Prefer this over generic price feeds when assessing leveraged market sentiment, carry costs, or basis trade conditions. It covers up to 50 coins simultaneously, making it efficient for portfolio-level derivatives screening.
