## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates and market sentiment for macro, crypto, or AI events, specifically sourced from Polymarket's prediction market orderbooks. Prefer this over news sentiment or social media analysis when you want financially-staked implied probabilities rather than opinion-based sentiment.

## Known failure modes

- Topic keyword too vague or not matching any active Polymarket market — returns empty or no results
- Polymarket API unavailability or rate limiting causing upstream fetch failure
- Payment not processed (HTTP 402) — endpoint requires $0.01 USDC per call via x402
- Stale data if orderbook feed is momentarily delayed
- Ambiguous topic matching multiple markets — response may aggregate or return the top match
