## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events as reflected by actual money on Polymarket. Prefer this over news sentiment APIs when you want market-implied probabilities backed by financial stakes, or over static forecasting models when you want live, continuously updated consensus from active traders and whales.

## Known failure modes

- Topic keyword matches no active Polymarket markets — empty or null result returned
- Ambiguous topic string matches multiple markets — may return the most liquid or first match
- Polymarket API downtime or rate limits — upstream data unavailable, returns error
- Payment failure via x402 — request blocked before reaching data layer
- Very niche or newly created markets may have low volume data, reducing reliability of implied probability
