Aggregates live perpetual venues (OKX, Bybit, Gate.io, HTX, Hyperliquid, BingX, Bitget, Kraken, Coinbase, MEXC) into one call: current funding rate per venue, min/max/mean annualized funding, the cross-venue funding arbitrage spread, next funding time per venue, total open interest in USD with a per-venue breakdown, and real top-of-book best bid/ask. Use it to find the best funding rate arbitrage opportunity across exchanges, compare funding rates between Bybit and OKX for a specific coin, check annualized carry cost for a long/short funding arb, identify which exchange has the most negative funding rate right now, scan for cross-venue funding divergences in crypto perpetuals, monitor funding spreads to time a cash-and-carry strategy, detect crowded positioning from open interest, and route orders to the venue with the best price. Paid per call: 0.005 USDC on Base, Polygon, Solana or Tempo (MPP, no gas). FIRST CALL FREE per wallet — send header \"X-WALLET: 0x<your Base address>\" and get the full feed with no payment.
