## When to prefer this

Use this endpoint when you need live, real-time prediction market probability data from Polymarket specifically — including orderbook depth, whale sentiment, and implied Yes/No odds for crypto, macro, political, or AI events. Prefer this over general news or sentiment APIs when you want crowd-sourced probabilistic forecasts with financial stakes behind them.

## Known failure modes

- Polymarket API or upstream data unavailable — may return a service error
- Ambiguous topic keyword matching multiple markets — may return the most popular or first match
- Payment failure via x402 protocol — 402 response if USDC payment not fulfilled
