## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events as reflected in Polymarket prediction markets, including orderbook depth and whale activity. Prefer this over general news or sentiment APIs when you want market-implied probabilities backed by real money rather than editorial opinion.

## Known failure modes

- No matching Polymarket market found for the given topic — returns empty or null market data
- Topic is too vague to resolve to a specific market — multiple markets returned with ambiguous selection
- Polymarket API unavailable or rate-limited — upstream timeout or error response
- Payment not processed (HTTP 402) — x402 micropayment handshake failure
- Stale data returned if orderbook feed has latency spikes
