## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market — especially for macro events (Fed rate decisions, elections), crypto events (ETF approvals, token launches), or AI policy events. Prefer this over news APIs or LLM-generated estimates when you want market-derived implied probabilities backed by actual money, orderbook depth, and whale sentiment rather than sentiment analysis or editorial opinion.

## Known failure modes

- Topic string too vague to match a specific market — returns multiple ambiguous results or no results
- Polymarket API upstream downtime — returns error or stale data
- Payment not completed via x402 — returns HTTP 402 requiring USDC payment
- Rate limit exceeded — returns HTTP 429 or equivalent error
