## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market for macro, crypto, political, or AI events — especially when you want both implied probabilities and volume/whale sentiment signals rather than just news or analyst opinions. Prefer this over news search endpoints when you need quantified market consensus probability rather than qualitative coverage.

## Known failure modes

- Ambiguous topic keyword matching multiple markets — may return multiple or wrong market
- Payment failure via x402 if USDC balance is insufficient
