## When to prefer this

Choose this endpoint when you need real-time crowd-wisdom probability estimates from Polymarket's live prediction markets, especially for macro, crypto, or AI events. It is ideal when you want market-implied probabilities backed by real money rather than poll-based or model-based forecasts. Prefer it over news sentiment tools when you need a single quantified probability with volume and whale-activity context.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null results
- Polymarket API or orderbook data temporarily unavailable — may return stale or error response
- Ambiguous topic string matches multiple markets — results may be for an unintended event
- Payment failure via x402 — call not executed if USDC micropayment not settled
- Rate limiting or quota exceeded — endpoint returns 429 or payment error
