Polymarket Markets

Market Lookup

FREE

Returns market metadata including question, outcomes with token IDs, volume, and status. Each market has exactly two outcomes (binary); multi-outcome scenarios are modeled as multiple markets grouped under one event.

Use this to discover token_id values needed for OHLCV and position queries, or to resolve a slug to identifiers. When no identifier is provided, returns a paginated list for discovery.
