## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events sourced directly from Polymarket orderbooks, especially when you want whale sentiment and volume signals alongside raw odds. Prefer this over general news or sentiment APIs when you need quantified market-implied probabilities rather than qualitative sentiment.

## Known failure modes

- No matching Polymarket market found for the given topic — returns empty or null result
- Stale or delayed data if Polymarket API is throttled or temporarily unavailable
- Ambiguous topic keyword matching multiple markets — may return multiple or mismatched results
- Payment failure via x402 protocol prevents access to the endpoint
- Network timeout or upstream Polymarket API downtime
