## 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 liquid prediction markets. It is especially valuable for gauging market sentiment beyond price charts — capturing implied probabilities and whale behavior that traditional data sources don't provide. Prefer it over general web search when you want structured, quantitative probability data rather than qualitative news articles.

## Known failure modes

- No matching Polymarket market found for the given topic — returns empty or null market data
- Topic query too vague to match a specific market — multiple ambiguous results returned
- Polymarket API or orderbook unavailable — upstream data fetch fails
- Payment not processed (HTTP 402) — x402 micropayment not completed before data is returned
- Rate limiting or quota exceeded on the agentdiet.dev hub — request throttled
