## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market for macro, crypto, or AI events — especially when you want implied odds, orderbook depth, or whale activity rather than news sentiment or traditional financial data.

## Known failure modes

- No active Polymarket market found for the queried topic — returns empty or null results
- Ambiguous topic keyword matches multiple markets — results may be broad or require refinement
- Polymarket API or data feed temporarily unavailable — may return timeout or upstream error
- Rate limiting or payment failure — HTTP 402 payment required before data is returned
- Topic too vague — returns irrelevant or loosely related markets
