How this service works
Cross-venue mark-price spread scan for crypto perpetuals — where the same perp trades at different marks across venues. Quoted spread is not net edge: it excludes fees, slippage and funding differences.
Output
Returns cross-venue mark-price spread data showing price differences across trading venues for a given perpetual futures ticker, including the venues with the highest and lowest mark prices and the spread magnitude in basis points. Note: quoted spread is gross and excludes fees, slippage, and funding rate differentials.
Example use cases
Example prompt
“Scan across all venues and show me the current mark-price spread for ETH perpetuals — I want to see which exchanges have the widest price gap right now.”
Technical details
Endpoint
GEThttps://api.usenami.io/v1/perp/arbitrage/priceWhen to prefer
Use this endpoint when you need a real-time snapshot of mark-price divergence across perpetual futures venues — ideal for identifying raw price-based cross-venue arbitrage candidates. Prefer this over the funding-rate arbitrage scanner when you want price-level spreads rather than rate spreads, and over the top-of-book endpoint when you need a multi-venue comparative view rather than a single venue quote.
