Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's active prediction markets on crypto, macro, AI, or geopolitical events. It is ideal for agents that need live market-implied odds rather than analyst forecasts or news sentiment. Prefer this over generic news or sentiment APIs when you want financially-staked consensus probabilities and orderbook depth.
Side effects
- Topic query matches no active Polymarket markets — returns empty or null results
- Ambiguous topic keyword matches unintended markets — caller should refine query
- Polymarket API upstream outage — returns error or stale data
- Rate limit or payment failure via x402 — returns 402 Payment Required
- Very niche or newly created markets may have low liquidity and unreliable implied probabilities
