Cross-platform matching-market records for a set of market slugs

Returns the cross-venue match record for each requested market slug, keyed by slug. Provider entries can include Polymarket, Kalshi, Predict.fun, and Hyperliquid. Slugs with no cross-venue match are silently omitted from the response object (not returned as null). When live=true, the Kalshi side of every matched entry is refreshed in-place with a live price (in cents / 100, 4 decimal places); a correction is applied when a stale price appears to be on the wrong side of a binary flip. Responses are cacheable, briefly when live=true, longer otherwise.

Query parameters

slugsstring required

Comma-separated list of market or matching slugs to look up. Include every slug carried by the discovery card because event slugs and per-outcome market slugs are distinct. Empty/blank entries are dropped.

live'true' | 'false'

Pass the literal string "true" to refresh Kalshi prices before returning. Any other value, including omission, is treated as false.

Response

Map of slug to matching-market record. Returns {} if slugs parses to no non-empty entries.

SportsMatchingMarketsResponse required

Map keyed by requested game slug. Slugs with no cache entry, or an unparseable cache value, are omitted from this object entirely.
