How this service works
Cross-exchange perpetual funding rate arbitrage, open interest, and best-execution for BTC/ETH/SOL. 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. Try it before you pay.
Output
Returns a structured JSON object containing: current funding rate per venue, annualized funding rates (min, max, mean), the cross-venue funding arbitrage spread, next funding timestamp per venue, total open interest in USD with a per-venue breakdown, and real top-of-book best bid/ask prices across all aggregated perpetual exchanges for the requested coin.
Example use cases
Funding arb opportunity scanner
“Which exchange has the most extreme funding rate for ETH right now, and what's the annualized spread between the highest and lowest venue? I'm looking for a funding arbitrage trade.”
Cash-and-carry strategy timing
“Show me the current annualized funding rates for BTC across all major perp exchanges — I want to figure out if the carry cost is high enough to justify a cash-and-carry position today.”
Crowded positioning detection via open interest
“What's the total open interest for SOL across Bybit, OKX, Hyperliquid, and Gate.io right now, and which venue is carrying the most? I want to see if positioning looks crowded before I put on a trade.”

Endpoint
POSThttps://funding-feed.kaminariouji.workers.dev/ip?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single aggregated view of perpetual funding rates, open interest, and best execution across 10+ major crypto exchanges simultaneously — particularly for funding arbitrage analysis, cash-and-carry strategy evaluation, or best-venue routing for BTC, ETH, or SOL. Prefer this over querying individual exchange APIs when cross-venue comparison and spread analysis are the primary goal.
Side effects
- Upstream exchange API downtime may cause missing per-venue data
- Rate limiting or payment failure returns 402 if USDC payment not processed
- Truncated or stale data if a venue's feed lags
- Response may omit certain venues if they are temporarily unavailable
- Invalid coin symbol returns error or empty result
