## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events as priced on Polymarket's decentralized prediction market. Prefer it over news APIs when you want market-implied probabilities rather than narrative reporting, or over static odds providers when you need live orderbook depth and whale sentiment. Ideal for research agents, trading bots, and decision-support tools that need calibrated probabilistic forecasts backed by real money.

## Known failure modes

- Ambiguous topic matches multiple unrelated markets — may return mixed results
- Payment required (HTTP 402) if x402 micropayment header is missing or invalid
