## When to prefer this

Use this endpoint when you need real-time crowd-wisdom probability estimates from Polymarket's decentralized prediction market for macro, crypto, political, or AI events. Prefer this over news sentiment APIs when you want market-implied probabilities backed by real money, or when you need orderbook depth and whale positioning data rather than just headlines or social sentiment.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Topic too ambiguous to match a specific market — multiple markets may be returned or none
- Polymarket API or upstream data feed outage — may return stale or error response
- Rate limiting or payment failure via x402 — returns 402 or 429 status
- Market has resolved and is no longer active — returns historical data or no live orderbook
