## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events, specifically sourced from Polymarket's prediction market orderbooks. Prefer this over news sentiment or analyst estimates when you want market-implied probabilities backed by real financial stakes and whale activity. Best suited for agentic workflows that need probabilistic event data rather than qualitative opinion.

## Known failure modes

- Topic keyword matches no active Polymarket market — returns empty or null result
- Ambiguous topic string matches multiple markets — response may aggregate or return top match only
- Polymarket API or data source temporarily unavailable — upstream fetch failure
- Payment not completed (HTTP 402) — endpoint requires x402 micropayment before response is returned
- Rate limit or quota exceeded — request rejected
