## 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 — particularly when you want implied probabilities backed by actual money, trading volume, and large-trader (whale) sentiment rather than survey-based or model-based forecasts.

## Known failure modes

- Stale or delayed data if Polymarket API is experiencing downtime
- Ambiguous topic string matching multiple markets — may return incorrect or blended results
- Payment failure via x402 if USDC balance is insufficient for the $0.015 per-call fee
