How this service works
Cross-exchange spread and arbitrage edge for any USDT perp: the best bid and ask on Bybit, OKX and Hyperliquid, with the best cross-venue edge in bps, pre-fee.
Output
Returns per-venue best bid and ask prices for the requested USDT perpetual, plus the best cross-venue arbitrage edge expressed in basis points (pre-fee), identifying which venues form the best buy/sell pair.
Example use cases
Spot live arb edge on BTC perp
“Check BTCUSDT perpetuals across Bybit, OKX, and Hyperliquid and tell me the current cross-venue spread in bps — I want to know if there's a pre-fee arbitrage edge worth acting on.”
Best venue to open ETH perp
“I want to go long ETHUSDT perpetual — which of Bybit, OKX, or Hyperliquid has the best ask price right now, and how wide is the spread between them?”
Monitor AVAX perp for spread divergence
“Pull the current best bid and ask for AVAXUSDT perps on all three venues and show me the cross-exchange spread in basis points so I can see if there's any pricing divergence.”
Technical details
Endpoint
GEThttps://x402.ochinimus.app/api/spread-arb?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, multi-venue best bid/ask comparison and pre-fee arbitrage edge calculation for USDT perpetuals across exactly Bybit, OKX, and Hyperliquid. Ideal for trading agents, arbitrage bots, or market-making workflows that need a single call to compare top-of-book across all three venues simultaneously rather than querying each exchange independently.
Side effects
- Missing or invalid 'symbol' query parameter returns an error
- Symbol not listed as a USDT perp on one or more venues may result in incomplete venue data
- Temporary exchange API downtime could cause missing venue quotes
- Rate limiting or payment failure may block the call
