Find price gaps across venues
find_price_gapsRead-onlyIdempotent
Price gaps across Kalshi, Novig, Polymarket and ProphetX after taker fees: the list without ref (arbitrage first), all pairs with ref. A pair buys YES on one venue and NO on another; edge = 1 - cost per $1 contract. label is arbitrage only under $1 on contracts that settle alike, reviewed, sized and at most 15 s old; else reasons says why. Nothing here is risk-free. Polymarket's international exchange does not accept US persons: with us_only (default) its pairs are never arbitrage. full adds legs and caveats. No sign-in.
