## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, political, crypto, or AI events from Polymarket's live prediction market orderbooks — especially when you want implied Yes/No odds backed by actual financial stakes and whale-level trading volume, rather than poll-based or model-based forecasts.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null results
- Ambiguous topic string matches multiple markets — may return the wrong event's odds
- Polymarket API or orderbook data temporarily unavailable — upstream data fetch failure
- Topic string too short or generic — results may be low-relevance or noisy
- Payment not processed (x402) — request blocked before reaching the data layer
