## When to prefer this

Use this endpoint when an agent needs real-time crowd-sourced probability estimates for macro, crypto, or AI events from the Polymarket prediction market, including orderbook depth and whale sentiment — particularly when you want market-implied probabilities rather than analyst forecasts or news sentiment. Prefer this over generic news search when you need a quantified probability signal derived from actual money at risk.

## Known failure modes

- Topic keyword matches no active Polymarket market — returns empty or null results
- Ambiguous topic string maps to multiple markets — may return the wrong event's odds
- Polymarket API downtime causes stale or unavailable data
- Rate limiting or payment failure (HTTP 402) if x402 USDC micropayment is not completed
- Very niche or newly created markets may have low liquidity and unreliable implied probabilities
