## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket for macro, crypto, political, or AI events — especially when you want implied odds, orderbook depth, volume, and whale sentiment in a single call rather than scraping Polymarket directly or using stale data sources.

## Known failure modes

- Topic too vague or ambiguous — no matching Polymarket market found, returns empty or low-confidence results
- Polymarket market not yet created for a very recent or niche event — no data returned
- Network or upstream Polymarket API downtime — service unavailable error
- Payment not processed (x402) — request blocked before reaching the oracle
- Rate limiting if too many calls made in rapid succession
