## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, AI, or geopolitical events as priced by actual traders on Polymarket. It is ideal for agents that need to incorporate market-implied probabilities rather than model-generated forecasts. Prefer this over news sentiment APIs when you want quantified conviction with skin-in-the-game trading volume backing the estimate.

## Known failure modes

- Topic keyword matches no active Polymarket markets — returns empty or null results
- Ambiguous topic string matches multiple unrelated markets — response may include unexpected markets
- Polymarket API downtime or rate limiting causes upstream fetch failure
- Very niche or newly created markets may have low liquidity, making implied probabilities unreliable
- Payment not processed (HTTP 402) — endpoint requires $0.01 USDC per call via x402
