Funding Rate Arbitrage Scanner ⚖️

Find risk-free-ish funding spreads between exchanges before you scan them by hand.

Perpetual futures charge a funding fee every 8 hours between longs and shorts. That fee is never quite the same on OKX, Bybit, Gate.io, KuCoin, Bitget, MEXC and Binance for the same asset — and when the gap is wide enough, traders go long on the cheap side and short on the expensive side: a delta-neutral position that pockets the spread regardless of which way the market moves.

This actor watches that spread for you, across 7 exchanges, continuously — including Binance, which most scrapers skip because its API geo-blocks datacenter IPs (this actor routes around that automatically, see Sources below).

Searches this actor ranks for: crypto funding rate arbitrage, perpetual futures funding scanner, delta-neutral arbitrage bot, cross-exchange funding rate comparison, Binance funding rate API, OKX Bybit KuCoin funding arbitrage, crowded positioning signal.

Why this actor exists

Checking funding rates by hand means opening four tabs, converting four different rate conventions to a comparable annualized number, and doing the long/short math yourself — every time you want to know if there's an edge right now. This actor does that comparison continuously and only surfaces a row when there's actually something to act on.

It doesn't stop at "here's a spread" — every arbitrage_opportunity also ships a confidence_score and execution_risk so you can tell a comfortable edge from one that's barely above the actionable threshold and could vanish before you get filled.

What you get

Two row types:

• Snapshot — current funding rate (raw + annualized %) per symbol per exchange
• Signal — a named, fired condition:

Signal	Meaning
arbitrage_opportunity	Cross-exchange funding spread wide enough to be worth a delta-neutral position — tells you exactly which exchange to long and which to short, plus a confidence score and execution-risk tier
extreme_funding	A single exchange's funding rate is unusually hot — crowded positioning, useful context even without a counterparty

No history needed: the spread is actionable the moment it's observed.

Confidence & execution risk

A spread that just barely clears the minimum threshold can slip back under it — or get eaten by fees and slippage — before you actually place the trade. The further above the threshold, the safer the edge:

execution_risk	Meaning
low	Spread is 3x+ the minimum threshold — comfortable room
medium	Spread is 1.5x–3x the threshold
high	Spread just cleared the threshold — thin margin, act fast or skip

confidence_score (0–1) is the same signal on a continuous scale, for anyone who wants to threshold it themselves rather than use the three tiers.

Sources (all public, no API key from you)

OKX, Gate.io, KuCoin, Bitget, MEXC — direct, key-less perpetual-futures endpoints. Binance and Bybit both block requests from datacenter IPs — this actor routes just those two calls through Apify's residential proxy automatically. Nothing to configure on your end, no proxy plan required, no API key anywhere.

Who this is for

You are a...	You use this to...
Funding arbitrageur	Scan 7 exchanges at once for a spread wide enough to run a delta-neutral position, with a confidence score so you know which ones are worth acting on
Perp trader	Spot crowded/extreme funding on a single exchange before opening a position
Bot builder	Feed clean, normalized JSON signals into your own execution pipeline — no per-exchange parsing to write
Researcher / model builder	Backtest funding-rate divergence across CEXs without stitching 7 different APIs yourself

Input (all optional)

Field	Default	Description
symbols	["BTC","ETH","SOL"]	Assets to compare (also supports XRP, DOGE)
exchanges	all 7	Which exchanges to include: okx, bybit, gateio, kucoin, bitget, mexc, binance
min_spread_apr_pct	32.85	Minimum annualized spread between two exchanges to fire arbitrage_opportunity
extreme_funding_apr_pct	54.75	Single-exchange annualized funding to fire extreme_funding

Pricing

Pay per result: $0.002 per row (snapshots + signals). Scanning 3 symbols × 7 exchanges is still a fraction of a cent per run.

Tips

• Schedule it every 15–30 min to catch spreads as they open and close.
• Widen symbols to cover more assets — more comparisons, more chances at a spread.
• Remember: funding-rate arbitrage is delta-neutral but not risk-free (execution slippage, exchange risk, margin requirements). This actor surfaces the spread — you manage the trade.

Roadmap

• More symbols beyond the current five, on request
• Considering: a rolling history mode for spreads that persist across multiple runs, not just instant snapshots
• Evaluating a couple more exchanges (Hyperliquid, Bitfinex) if there's demand
