Live perpetual funding rates and fee-adjusted funding-arbitrage opportunities across 8 decentralized perp DEXs, in one call. Pay per result — no monthly subscription.

• arb — ranked arbitrage opportunities. Per coin: which venue to short (high funding), which to long (low/negative), the spread, and net APR after round-trip taker fees. Thin/stale markets filtered out.
• rates — raw funding rate per venue per coin: rate, interval, annualized APR, mark price, open interest.

Notes

Data fetched live from public venue APIs. Net APR subtracts annualized round-trip taker fees over a 7-day hold — an estimate, not a guarantee. Not financial advice.
