## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events from Polymarket's prediction market, including volume signals and whale positioning. Prefer this over news sentiment endpoints when you want financially-staked implied probabilities rather than qualitative sentiment. Best suited for agents doing event-driven trading research, risk assessment, or forecasting workflows.

- Ambiguous topic keyword matching multiple markets — may return the wrong or most popular market
- Payment required (HTTP 402) if x402 credentials are missing or insufficient
