Cross-Exchange Arbitrage

Cross-exchange arbitrage exploits funding rate differentials for the same asset across two exchanges. By going long on the exchange paying you and short on the exchange charging you, you capture the net rate as profit. This endpoint scans 10 exchanges, pairs the best long/short combination per asset, and returns opportunities sorted by APR.

List cross-exchange opportunities
