Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events from Polymarket's liquid prediction markets, especially when you want implied Yes/No odds, volume context, and whale sentiment rather than generic news sentiment or analyst forecasts.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Ambiguous topic string matches multiple markets — may return aggregated or partial data
- Stale data if Polymarket orderbook API is temporarily unavailable
- Payment failure via x402 protocol resulting in 402 response before data is returned
- Rate limiting if too many queries are fired in rapid succession
