## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for discrete macro, crypto, political, or AI events from Polymarket's decentralized prediction market. Prefer this over news sentiment APIs when you want market-implied probabilities backed by actual money, or over centralized odds APIs when you want on-chain DeFi-native event probability data with whale activity context.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Ambiguous topic resolves to wrong market — caller should use more specific event phrasing
- Polymarket API or orderbook data temporarily unavailable — upstream data outage
- Rate limiting or payment failure via x402 — returns 402 Payment Required
- Stale data if Polymarket market has resolved or been delisted
