## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events as priced by actual Polymarket traders with skin in the game. It is preferable to news sentiment or analyst forecasts when you want market-implied probabilities backed by real money, and ideal for agents that need up-to-the-minute odds without scraping Polymarket directly.

## 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 — may return stale or error response
- Overly broad or ambiguous topic string matches multiple markets — results may aggregate or return the most liquid match
- Payment of $0.01 USDC via x402 fails or is not supported by the calling client — request rejected before data is returned
