{"uid":"cap_MxpkRWFqrRUtJLnPgLDsy","slug":"dex-price-spread-b5a2501f","name":"DEX Price Spread","description":"A token on several Base DEXes should cost about the same on each; a gap is either an arbitrage window or, on a thin pool, a mispricing that signals wash/manipulation. Compares the price across the LIQUID venues (over a floor, default $5k): tight (trustworthy), arb_window, wide (likely mispricing), or single_venue (one pool, as manipulable as it is thin). Separates real arbitrage from thin-pool noise. Snapshots — confirm with a live quote.
