## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction markets for political, macroeconomic, crypto, or AI events — especially when you want both implied probabilities and whale sentiment in a single call. Prefer this over general news or financial data APIs when you want market-consensus probability rather than price data or editorial opinion.

## Known failure modes

- Topic keyword too vague or unrecognized — returns empty results or no matching market
- Market not yet listed on Polymarket for the queried event — no data returned
- Payment not processed (HTTP 402) — endpoint requires $0.01 USDC per call via x402
- Rate limit or API gateway timeout — service temporarily unavailable
- Stale or low-liquidity market — orderbook data may be thin or unreliable
