## When to prefer this

Choose this endpoint when you need real-time crowd-implied probabilities and sentiment from Polymarket specifically, including orderbook depth and whale activity — especially for macro events, crypto milestones, or AI/policy outcomes. Prefer this over general news sentiment APIs when you want market-based probability estimates rather than narrative sentiment.

- Stale data if Polymarket API is temporarily unavailable or rate-limited
