Polymarket Search Markets

Search and browse Polymarket prediction markets. Use orderBy 'volume'/'newest'/'liquidity' to browse all active markets without any filters. Add a query for keyword search, or date filters (endDateMin/Max) for time-bounded browsing. Returns markets with question, outcomes, prices, volume, liquidity, and parent eventSlug/eventTitle. Search ranking: keyword queries match against EVENT titles, then surface that event's markets — so per-game markets (e.g. 'Belgium vs. Egypt') only appear when the query matches the event title. Tournament-level queries like 'World Cup 2026' bury per-game events under featured tournament markets (e.g. 'World Cup Winner'); for specific matchups, search by team/entity names alone (e.g. 'Belgium Egypt'). Absence from one query does not mean absence from Polymarket. Query vs tag: use `query` for keyword/entity search (e.g. 'bitcoin', 'Belgium Egypt'); use `tag` to BROWSE a whole category by its Polymarket slug (e.g. tag: 'weather' | 'sports' | 'politics' | 'fifa-world-cup'), which returns the same live markets as polymarket.com/<slug>. Prefer `tag` for topic/category requests — keyword search misses category markets whose text omits the word (e.g. query 'weather' finds nothing, but tag 'weather' surfaces the live 'Highest temperature in <city>' markets). A bare `tag` browses by volume. Ideal for: market discovery, automated market selection, finding short-duration markets, dashboards.
