## When to prefer this

Use this endpoint when you need real-time or recent trade history from Polymarket prediction markets — specifically trade-level data (price, size, who traded). Prefer this over polymarket_events (which returns market metadata) when you want to analyze market momentum, detect large trades, or track price movement through actual transaction history.

## Known failure modes
