## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events from Polymarket specifically — including orderbook depth, implied Yes/No odds, volume, and whale sentiment — rather than general news sentiment or social media opinion aggregation. It is best suited for financial and event-driven agents that need live prediction market signals to inform decisions or reports.

- Ambiguous topic maps to multiple markets — may return the wrong event
- Polymarket API upstream unavailability — service returns error or stale data
- Payment required error (HTTP 402) if x402 payment header is not provided
