```

## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events as reflected by actual money at stake on Polymarket. It is ideal over general news or sentiment APIs when you want financially-incentivized market consensus rather than editorial opinion or social media chatter. Best for crypto-native or prediction-market-aware agents that need calibrated probability signals.

## Known failure modes

- No matching Polymarket market found for the queried topic — returns empty or null results
- Ambiguous topic keyword matches multiple markets — may return the most relevant or a list
- Polymarket API downtime or rate limiting causing stale or missing data
- Payment failure via x402 protocol resulting in 402 response with no data returned
- Very new or low-liquidity markets may have unreliable implied probability data
