## When to prefer this

Choose this endpoint when you need live, crowd-sourced probability estimates for macro, crypto, or AI events as priced by real money on Polymarket — particularly when you want implied probabilities, trading volume context, or whale sentiment signals rather than news or analyst opinions. Prefer this over general news APIs when you need quantified market consensus or decentralized prediction market data specifically from Polymarket.

## Known failure modes

- Topic not found or no active Polymarket market matches the query — returns empty or null market data
- Ambiguous topic keyword matches multiple markets — may return aggregate or first-matched result
- Polymarket API or data feed unavailability causes stale or missing odds
- Payment not processed (HTTP 402) — endpoint requires $0.01 USDC per call via x402
- Rate limiting or quota exhaustion returns an error response
