## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction markets for macro, crypto, AI, or geopolitical events — particularly when you want implied Yes/No odds, orderbook depth, volume, and whale sentiment in a single call rather than scraping Polymarket's UI directly.

## Known failure modes

- Topic keyword matches no active Polymarket market — returns empty or null results
- Polymarket API upstream outage causes stale or unavailable data
- Overly vague topic yields ambiguous multi-market results with conflicting probabilities
- Payment (x402 micro-payment at $0.015) fails or is not honored, blocking the request
- Rate limiting or quota exhaustion on the underlying Polymarket data feed
