## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events from Polymarket's active prediction markets, including orderbook depth and whale sentiment signals. Prefer this over general news or sentiment APIs when you want market-implied probabilities backed by actual money rather than social media sentiment scores.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null market data
- Stale or delayed orderbook data if Polymarket API is temporarily unavailable
- Ambiguous topic keyword matching multiple unrelated markets — may return mixed or irrelevant results
- Payment failure via x402 if insufficient USDC balance — returns HTTP 402
- Rate limiting or service degradation resulting in timeout or partial response
