Use this to search Quotient-covered markets by meaning, taxonomy, asset, venue, or historical cutoff. Results carry quote provenance plus Q and venue odds captured at the selected forecast. Polymarket International and Kalshi use verified live pricing or null; other venues label graph snapshots stale. Use as_of for discovery and the forecast-time pair for historical spreads, including since-closed markets.
