## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for discrete binary events — especially macro, crypto, political, or AI events — and want implied odds, orderbook depth, and whale positioning rather than a news summary or analyst opinion. Prefer over general search when you specifically need market-derived probability signals from Polymarket.

## Known failure modes

- Topic not found on Polymarket — no active market exists for the queried keyword
- Ambiguous topic matches multiple markets — may return the most relevant or an error
- Polymarket API unavailability or rate limiting causing empty or partial responses
- Payment failure (x402) blocking the request if USDC balance is insufficient
- Stale data if market has very low liquidity or has recently closed
