## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, political, crypto, or AI events from Polymarket's prediction market orderbooks, especially when whale sentiment and live volume context matter. Prefer this over general news search when you want quantified market-implied probabilities rather than narrative coverage. It is especially useful for agents performing event-driven trading analysis, political forecasting, or risk assessment based on decentralized prediction market signals.

## Known failure modes

- No matching Polymarket market found for the given topic — returns empty or low-confidence result
- Polymarket API or data source unavailable — may return upstream error
- Ambiguous topic keyword matching multiple markets — results may cover unintended markets
- Payment not processed (402) — endpoint requires x402 USDC micropayment per call
- Rate limiting or quota exceeded for the upstream data feed
