## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's decentralized prediction market, particularly for macro events, crypto price milestones, political outcomes, or AI policy questions. Prefer this over traditional news or sentiment APIs when you want market-implied probabilities backed by actual money at stake rather than survey-based or social sentiment data.

## Known failure modes

- No matching Polymarket market found for the topic keyword — returns empty or null result
- Topic query too ambiguous to resolve to a specific market — may return multiple or incorrect markets
- Stale data if Polymarket orderbook is temporarily unavailable or rate-limited upstream
- Payment failure via x402 if USDC balance is insufficient
- Network timeout if the live orderbook fetch exceeds response threshold
