## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events as reflected in actual money on the line on Polymarket. It is best when the user wants implied odds, Yes/No probability, volume, or large-trader sentiment rather than news or historical data. Prefer it over general news APIs when you want market-derived probabilities rather than editorial coverage.

## Known failure modes

- Topic keyword returns no matching Polymarket markets (unknown or too niche a question)
- Polymarket API or data feed is temporarily unavailable, returning an error or stale data
- Ambiguous topic keyword matches multiple markets, potentially returning mixed or unexpected results
- Payment not processed correctly via x402, resulting in 402 error and no data returned
