Crypto Perp Funding Rate Scanner: 5 Exchanges + Spreads

Crypto Perp Funding Rate Scanner

One run returns the current funding rate, annualised yield, open interest and next funding time for every USDT/USDC perpetual on Binance, Bybit, OKX, Hyperliquid and Gate, plus a cross-exchange spread row per asset that shows where funding is highest and lowest. 3,500+ contracts in about 5 seconds. No API keys, no login.

Use it for funding-arbitrage screens, carry-trade monitoring, basis dashboards, or as a tool an AI agent calls before it sizes a perp position.

What you get

Rate rows (type: "rate"), one per contract:

Field	Example
base / quote	BTC / USDT
exchange	binance, bybit, okx, hyperliquid, gate
symbol	BTCUSDT, BTC-USDT-SWAP, BTC-PERP
markPrice	74422.1
fundingRatePct	0.0076 (per funding interval)
fundingIntervalHours	8 (Hyperliquid is 1, some Binance/Bybit contracts 4)
annualizedPct	8.29 — the rate scaled to a year, so 1h and 8h venues compare directly
nextFundingTime	ISO timestamp
openInterestUsd	where the exchange publishes it
snapshotTime	when the run took its snapshot

Spread rows (type: "spread"), one per asset listed on 2+ exchanges: highest and lowest annualised funding, which venue each is on, and spreadAnnualizedPct (the number a funding-arb trade earns before fees). Spread rows come first, biggest spread on top.

Example spread row:

{ "type": "spread", "base": "SUI", "exchanges": 5, "highestExchange": "binance", "highestAnnualizedPct": 10.95,
  "lowestExchange": "bybit", "lowestAnnualizedPct": -17.0, "spreadAnnualizedPct": 27.95, "snapshotTime": "2026-11-10T14:52:11.000Z" }

Input

Field	Default	Notes
exchanges	all five	Any subset
assets	empty = everything	Base assets to keep, e.g. ["BTC","ETH","SOL"]
minAbsAnnualizedPct	0	Keep only rates at least this far from zero (either sign); handy for "show me extreme funding"
includeSpreads	true	Add the per-asset spread rows
maxResults	2000	Cap on rows returned
proxy	Apify residential, country AU	Used only for Binance and Bybit, which refuse US datacenter IPs (HTTP 451 / 403). Datacenter proxies do not work for them; residential does (about 1 MB per run). OKX, Hyperliquid and Gate are fetched directly.

A full scan with no filters is ~3,500 rate rows + ~900 spread rows. With assets set to a few coins it is a handful of rows and completes in a couple of seconds.

How the numbers are built

• Funding rates are read from each exchange's public market-data endpoint at run time (Binance premiumIndex, Bybit v5/market/tickers, OKX public/funding-rate, Hyperliquid metaAndAssetCtxs, Gate futures/usdt/contracts).
• annualizedPct = fundingRate × (24 / fundingIntervalHours) × 365 × 100. Funding intervals come from the exchange (Binance fundingInfo, Bybit instruments-info, Gate funding_interval, OKX funding timestamps, Hyperliquid hourly).
• Open interest is converted to USD with the mark price where the exchange gives it in contracts.
• Nothing is cached: every run is a fresh snapshot.

Scheduling and agents

Schedule it hourly to build a funding history dataset, or call it from an AI agent / MCP client when a question needs live funding. The output is flat JSON with stable field names.

Limits

• Exchange APIs occasionally rate-limit; a failed exchange is logged and skipped, the others still return.
• Binance and Bybit geo-block US IPs. Keep the residential proxy on (default) or those two will return nothing; the run still succeeds with the other three.
• Data only, not financial advice. Funding-arb trades carry execution, basis and liquidation risk that this scanner does not measure.

Cost

Pay per event, no subscription. You pay only for what a run returns.

Event	Price
Scan start, once per run	$0.01
Result row	$0.0004

A BTC, ETH and SOL check returns about 25 rows and costs about 2 cents. A scan at the default cap of 2,000 rows costs $0.81. Set assets or maxResults to control the bill.
