Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events as reflected in actual money-backed prediction markets on Polymarket. Prefer this over news sentiment or social media analysis when you want market-implied probabilities backed by real capital and orderbook depth, including whale-level position signals.

## Known failure modes

- Polymarket API upstream downtime — service may return an error or stale data
- Overly vague topic string returns multiple ambiguous market results
- Payment not completed via x402 — endpoint returns HTTP 402 and denies access
