Polymarket Events

Query Parameters

event_slugstringrequired

Polymarket event slug (identifies a multi-outcome question with several nested markets). Known World Cup match sibling slugs are expanded to the canonical match group. Discover slugs via /v1/search/prediction-market?platform=polymarket&q={keyword}. For a single Yes/No market, use /polymarket/markets with market_slug instead — this endpoint only accepts event_slug, not market_slug.

Example: what-price-will-bitcoin-hit-before-2027
