## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability data for macro, crypto, geopolitical, or AI events from Polymarket — especially when you want implied market odds, volume context, and whale sentiment in a single call. Prefer this over general news or sentiment APIs when you need a quantified probability estimate backed by financial stakes.

## Known failure modes

- Topic keyword returns no matching Polymarket market — response may be empty or return a best-guess partial match
- Stale or delayed orderbook data if Polymarket API is temporarily unavailable
- Ambiguous topic string matches multiple markets — response may include multiple markets or pick the most relevant one
- Payment failure or 402 response if x402 USDC micropayment is not completed
- Rate limiting if the endpoint is called too frequently
