## When to prefer this

Choose this endpoint when you need live, crowd-sourced probability estimates for macro, crypto, political, or AI-related events sourced directly from Polymarket's prediction market orderbooks. It is particularly useful when you need implied probability alongside volume and whale sentiment signals, rather than just a headline probability figure. Prefer this over news-based or model-based forecasts when you want market-priced consensus.

## Known failure modes

- Topic not found on Polymarket — returns empty or null results if no matching market exists
- Ambiguous topic keyword matching multiple markets — may return unexpected or blended results
- Stale data if Polymarket API is temporarily throttled or unavailable
- Payment failure (HTTP 402) if USDC balance is insufficient for the per-call fee
- Rate limiting if too many queries are submitted in rapid succession
