## 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 orderbook-derived implied probabilities and whale sentiment rather than news sentiment or analyst forecasts. Prefer this over general news APIs when you want market-priced probability signals.

## Known failure modes

- Polymarket API or orderbook data temporarily unavailable — upstream timeout or error
- Payment not processed (HTTP 402) — x402 micropayment required before data is returned
