## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates and market sentiment for macro, crypto, or AI events from Polymarket's decentralized prediction market. Prefer this over news sentiment tools when you want quantified probabilistic consensus backed by financial stakes rather than qualitative opinion, or when you need whale positioning data alongside standard odds.

## Known failure modes

- Topic keyword does not match any active Polymarket market — returns empty or no-match result
- Polymarket API upstream unavailability causing stale or failed data fetch
- Ambiguous topic string matching multiple unrelated markets — may return incorrect market data
- Payment (x402) not processed — returns HTTP 402 requiring micropayment before data is returned
