Sports

All markets for a single sports event

Resolves markets for one game. If game_id is given, tries a cached lookup first, falling back to a live Polymarket lookup on a miss. If only slug is given, first resolves the event's gameId via a live Polymarket lookup, then performs the same event-markets lookup. Returns an empty markets list if neither parameter resolves to an event. At least one of game_id or slug should be supplied; both are optional and unvalidated strings.

Query parameters

game_idstring

Upstream sports game ID to look up directly.

slugstring

Polymarket market slug used to discover the event's gameId when game_id is not known.

Response

Markets for the resolved event. gameId echoes the resolved id, or falls back to the raw game_id/slug query value ("unknown" if neither was supplied) when nothing could be resolved.

gameIdstring required

Resolved gameId, or the raw game_id/slug query value ("unknown" if neither resolved).
