## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events from Polymarket's prediction market. It is especially useful for gauging whale sentiment and implied market odds rather than analyst forecasts or news-based summaries. Prefer this over general news APIs when you want quantified probability signals backed by real money and orderbook depth.

## Known failure modes

- No matching Polymarket market found for the topic — returns empty or null result
- Topic is too vague to resolve to a specific market — ambiguous query
- Polymarket API downstream outage causing stale or unavailable data
- Payment failure via x402 if USDC balance is insufficient
- Rate limiting if too many requests are made in quick succession
