## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's decentralized prediction market, especially for crypto, macro, political, or AI events where market-implied odds are more valuable than news sentiment alone. Prefer this over general news search when you want quantified probability and volume-weighted whale positioning data.

## Known failure modes

- Stale or unavailable orderbook data if Polymarket API is down
- Ambiguous topic string matching multiple unrelated markets
- Payment failure via x402 resulting in 402 response with no data
- Empty result set for niche or low-volume market topics
