How this service works

Crypto funding rate scanner API (perpetual futures). Cross-venue perp funding scan over Hyperliquid, dYdX v4 and Paradex: pass a watchlist (symbols=BTC,ETH,SOL, up to 25) or universe=all (every market above min_oi_usd, default $1M). Returns the highest and lowest funding (APR), the widest cross-venue funding spreads, the market-wide OI-weighted funding and share of markets with positive funding, with a per-asset positioning label. Fail-closed. Not financial advice.

Output

Returns a JSON object with overall market sentiment (read, positive_funding_share_pct, OI-weighted funding APR), a list of assets with lowest (most negative) funding rates per venue, a list of assets with the widest cross-venue funding rate spreads, venue availability status, scan mode, confidence level, and a disclaimer. Each asset entry includes per-venue funding rate (8h and APR), open interest in USD, premium percentage, and positioning label (crowded_short, long_bias, neutral).

Example use cases

Funding arbitrage opportunity scan

“Use PerpRadar to scan all perp markets above $2M open interest and show me the top 15 assets with the widest funding rate spreads across dYdX, Hyperliquid, and Paradex — I want to find cash-and-carry arb setups.”

Crowded short detection for contrarian trades

“Check PerpRadar for the 10 perp assets with the most negative funding rates right now — I'm looking for crowded short situations that might be worth fading.”

Targeted funding rate check for specific tickers

“Pull the current funding rates and open interest from PerpRadar for BTC, ETH, SOL, and ADA across all available venues and tell me which one has the most favorable long funding rate.”

When to prefer

Choose PerpRadar when you need real-time cross-venue perpetual futures funding rate data from decentralized venues (dYdX, Hyperliquid, Paradex) specifically. It is purpose-built for funding rate arbitrage discovery and positioning analysis, unlike generic crypto price APIs that don't provide cross-venue funding comparison or open-interest-weighted signals.

Side effects

One or more venues may fail to respond (listed in sources_failed), reducing cross-venue spread calculations
symbols parameter with invalid tickers returns empty or partial results
universe=all with very low min_oi_usd may time out or return too many assets
Neither symbols nor universe=all provided results in a validation error
Rate limits or payment failures return 402 or 429 errors
