## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events from Polymarket — especially when you want market-implied odds rather than analyst forecasts, and when whale positioning or volume context matters for decision-making.

## Known failure modes

- Topic keyword returns no matching Polymarket market — empty or null result
- Ambiguous topic matches multiple markets — may return best-guess or require refinement
- Polymarket API downtime or rate limiting causes stale or failed response
- Very niche topics may have low volume markets with wide spreads
- Payment failure (x402) returns 402 status with payment instructions
