How this service works
Xynaptic Crypto Derivatives — perp market vitals: funding rate (hourly + annualized), open interest in USD, futures basis (mark vs oracle), max leverage. Parameter: ?asset=BTC. Hyperliquid perp data.
Output
Returns a JSON object containing the asset's perpetual futures market vitals: hourly funding rate, annualized funding rate, total open interest in USD, futures basis expressed as the spread between mark and oracle price, and the maximum available leverage for the specified asset.
Example use cases
Pre-trade funding rate check
“Before I open a long BTC perp position, can you pull the current hourly and annualized funding rate so I know whether longs are paying shorts?”
Open interest market sentiment
“What's the current open interest in USD for BTC perpetual futures? I want to gauge overall market exposure before making a trading decision.”
Basis arbitrage opportunity scan
“What's the current futures basis between the BTC mark price and oracle price on Hyperliquid? I'm looking for basis arbitrage opportunities.”

Endpoint
GEThttps://api.xynaptic.io/v1/crypto-derivatives?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time perpetual futures market data specifically from Hyperliquid — especially funding rates, open interest, and basis — for a single crypto asset. Prefer this over generic price feeds when the derivative market structure (funding, leverage, basis) is what matters, not just spot price.
Side effects
- Unsupported or invalid asset symbol returns an error or empty response
- Hyperliquid data feed outage may cause stale or missing data
- Missing required ?asset= query parameter results in a 400 bad request
- Payment failure (x402) blocks access if USDC payment is not completed
