Example prompt: What are the live Polymarket odds right now on whether the Fed will cut interest rates this quarter — show me the Yes/No probabilities and any whale sentiment?

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market for macro, political, crypto, or AI events — especially when you want market-implied odds (not just news sentiment) and whale trading signals. Prefer this over news search when you want a single quantified probability rather than qualitative coverage.

## Known failure modes

- Topic keyword matches no active Polymarket markets — returns empty or null results
- Ambiguous topic string matches multiple unrelated markets — results may be noisy
- Polymarket API downtime causes stale or unavailable data
- Rate limiting or payment failure (HTTP 402) blocks the request
- Very niche or newly created markets may have low liquidity, making odds unreliable
