## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events from Polymarket's prediction market — especially when you want not just odds but also volume and whale-level orderflow sentiment. Prefer this over static news or sentiment APIs when you want market-implied probabilities reflecting actual financial stakes.

## Known failure modes

- No matching Polymarket market found for the given topic — returns empty or low-confidence result
- Topic string too vague to resolve to a specific market — may return multiple unrelated markets
- Polymarket API or data feed temporarily unavailable — upstream fetch failure
- Payment required (HTTP 402) if x402 micropayment is not attached or fails
- Rate limiting if too many requests are sent in short succession
