Live Cross Dex Arbitrage Scanner For Op Mainnet API

Live cross-DEX arbitrage scanner for OP Mainnet. Scans every liquid pair across SushiSwap and Uniswap v3 fee tiers and returns ranked cross-venue spreads: where to buy, where to sell, spread in bps, optimal trade size and gross USD at that size. GROSS, before gas and MEV. Venues below a liquidity floor are excluded, so a spread against a dust pool is never reported as an opportunity. For arbitrage bots on Optimism / OP L2.
