## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for specific events — especially macro, crypto, or AI-related outcomes — and want both the implied odds and large-trader sentiment in a single call. Prefer this over general news or sentiment APIs when you need quantified probability from a liquid prediction market rather than qualitative opinion.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Polymarket API downtime or rate limiting causing stale or unavailable data
- Ambiguous topic string matching multiple markets — may return unexpected market
- x402 payment failure if USDC balance is insufficient, blocking the request
- Very niche or newly-created markets may have low liquidity and unreliable probability data
