Use this endpoint when you need real-time crowd-sourced probability estimates and market-implied odds for macro, crypto, or AI events, especially when you want whale sentiment and orderbook depth in addition to simple price quotes. Prefer this over news sentiment or social media scrapers when you need financially-weighted probability signals from actual prediction market participants.

## Known failure modes

- Polymarket API unavailable or rate-limited — upstream data fetch fails
- Topic string too short or blank — rejected by input validation (minLength:1)
- Network timeout fetching live orderbook data
