## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events as reflected by actual money wagered on Polymarket. Prefer this over news sentiment tools when you want market-implied probabilities backed by financial stakes and orderbook depth rather than editorial opinion.

## Known failure modes

- Topic keyword matches no active Polymarket market — returns empty or null results
- Ambiguous topic yields multiple markets with no clear match
- Polymarket API downstream outage causes stale or missing data
- Very niche or obscure topics may have low-liquidity markets with unreliable probabilities
- Rate limiting or payment failure (HTTP 402) if micropayment not processed
