How this service works
Crypto perpetual-futures data from on-chain perp DEXs: per market the funding rate (hourly + annualized %), open interest (USD and base units), mark & oracle price, 24h volume and 24h price change. Ranked by open interest; filter by `coins` or `limit`. Data source: Hyperliquid (dYdX fallback).
Output
A ranked list of derivatives markets (futures/perpetuals) sorted by open interest, optionally filtered to specified coin symbols, up to the requested limit. Each market entry likely includes the coin symbol, contract type, open interest value, and exchange or venue details.
Example use cases
Monitor largest open interest markets
“Show me the top 50 crypto derivatives markets ranked by open interest right now — I want to see which coins have the biggest futures and perps activity.”
Filter perps data for specific coins
“Get me the current derivatives market data for BTC, ETH, SOL, and BNB — ranked by open interest so I can see which has the most activity.”
Track derivatives market overview
“What do the top 30 crypto derivatives markets look like right now by open interest? Give me the full market picture across futures and perpetual swaps.”

Endpoint
POSThttps://crypto.openverbs.com/v1/derivatives?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need live derivatives market data ranked by open interest and want to filter by specific cryptocurrencies. Prefer this over spot price endpoints when the user's question is about futures, perpetuals, or open interest rather than token spot prices. Ideal for traders, analysts, or agents monitoring derivatives activity or building dashboards around futures market size.
Side effects
- Invalid coin symbol in the coins array returns an error or empty results for that symbol
- Limit exceeding 250 is rejected with a validation error
- Empty coins array with no matching markets returns an empty result set
- Network or upstream data provider outage causes delayed or unavailable market data
- Malformed request body causes a 400 bad request error
