How this service works
Cross-venue Hyperliquid+OKX+dYdX perp funding rates — top coins by 24h notional volume, per-venue funding + arb spread (bps) + cheapest-long/richest-short venue, premium/basis, annualized_hl, annualized_okx, LONGS_PAY/SHORTS_PAY/NEUTRAL signal, next_funding_ts, mark/oracle prices, open interest.
Output
A list of top coins ranked by 24h notional volume, each with per-venue funding rates, arbitrage spread in basis points, cheapest-long and richest-short venue, premium/basis, annualized funding rates for Hyperliquid and OKX, a LONGS_PAY/SHORTS_PAY/NEUTRAL signal, next funding timestamp, mark and oracle prices, and open interest.
Example use cases
Find profitable funding rate arb opportunities
“I want to find the best funding rate arbitrage spreads right now across Hyperliquid, OKX, and dYdX — show me which coins have the widest spreads and tell me exactly where I should go long and where I should short to capture that arb.”
Route long positions to cheapest venue
“I'm looking to open a long position on the top 10 perps by volume, but I want to make sure I'm using the cheapest venue for each one — can you show me where the best entry prices are across all three exchanges and flag any coins where there's a huge difference?”
Monitor directional signals for trading
“Pull the latest LONGS_PAY and SHORTS_PAY signals across all venues for the top movers — I want to see which coins are signaling that shorts are currently overleveraged and paying the most funding, so I can potentially fade into those positions.”
Technical details
Endpoint
GEThttps://x402-data-api.sigrunner.workers.dev/crypto/fundingWhen to prefer
Use this endpoint when you need a single aggregated view of perpetual futures funding rates across Hyperliquid, OKX, and dYdX simultaneously — especially for funding rate arbitrage discovery, venue comparison, or directional signal (LONGS_PAY/SHORTS_PAY). Prefer over venue-specific APIs when cross-venue spread analysis or best-venue routing is required.
Side effects
- Payment not included or insufficient — returns 402 Payment Required
- limit parameter exceeds 100 — may return error or be clamped
- Upstream venue API unavailable — partial or stale data for affected venue
- Invalid query parameter type — may return 400 or unexpected results
