## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events directly from Polymarket's prediction market orderbooks, especially when you want implied probabilities, trading volume context, and whale sentiment rather than news sentiment or analyst forecasts.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null results
- Polymarket API or data source is temporarily unavailable — upstream timeout error
- Ambiguous topic string matches multiple markets — response may return multiple or unintended markets
- Payment failure via x402 — request not processed if USDC payment is not completed
