## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market orderbooks for macro, crypto, or AI events — especially when you want implied probability percentages, trading volume context, and large-trader (whale) sentiment in a single call. Prefer this over general news sentiment when you want market-priced probabilities rather than editorial opinion.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Topic string too vague to resolve to a specific market — ambiguous results returned
- Payment not received via x402 — HTTP 402 returned before data is served
- Polymarket API or orderbook data temporarily unavailable — stale or error response
- Rate limit exceeded for the underlying data feed — throttled response
