Two venues. A shared view.
Find matched Kalshi and Polymarket markets and compare their quoted probabilities.
Matched markets
/cross-platform/matchesRESTRetrieve matched markets with a configurable confidence threshold. Matches use offset pagination and return a data array with meta containing total, count, limit, and offset.

verifiedOnlystring · optionalSet to true to restrict results to verified matches.
Price divergence
/cross-platform/arbitrageRESTQuery matched markets whose quoted probabilities diverge by at least your threshold. A minDivergence of 0.03 represents three percentage points.
limitnumber · default 20Results to return, from 1 to 100.
minDivergencenumber · default 0.03Minimum probability divergence, from 0 to 1.
minScorenumber · default 0.5Minimum matched-market confidence, from 0 to 1.
Price divergence is an analytical observation. Match confidence, settlement conditions, fees, liquidity, and execution timing all affect whether two positions are economically comparable.
Venue coverage
Cross-venue matching currently covers Kalshi and Polymarket. Market discovery and wallet endpoints have their own datasets; a matched pair does not imply identical analytics coverage on both venues.
