## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's live prediction markets — especially for macro, crypto, or AI events. Prefer this over news APIs when you want quantified market consensus (implied probability %) rather than qualitative reporting. Best for agents that need to reason about event likelihood using actual money-backed prediction market signals, including volume and whale behavior, rather than sentiment scores or polls.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Polymarket API or orderbook data temporarily unavailable — returns upstream error
- Topic string too vague or ambiguous — returns multiple unrelated markets or low-confidence match
- Payment not settled via x402 — endpoint returns HTTP 402 and no data
- Rate limiting or upstream Polymarket throttling — delayed or partial response
