## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events sourced directly from Polymarket's live orderbook — especially when you want implied yes/no odds, volume, and whale sentiment in a single call. Prefer this over general news or sentiment APIs when you need quantified market-implied probabilities rather than qualitative opinion.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null market data
- Ambiguous topic string matching multiple markets — may return multiple or incorrectly ranked results
- Polymarket API or orderbook data temporarily unavailable — may return stale or error response
- Payment (x402 $0.01 USDC) not fulfilled — request rejected with 402 Payment Required
- Misspelled or overly broad topic keyword yields irrelevant market results
