## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events as reflected in actual money-at-stake prediction markets. Prefer this over news sentiment or analyst forecasts when you want market-implied probabilities backed by orderbook liquidity and whale position data specifically from Polymarket.

## Known failure modes

- Topic keyword matches no active Polymarket market — returns empty or null results
- Ambiguous topic resolves to wrong market — verify returned market title matches intent
- Polymarket API downtime or rate limiting — may return stale or error response
