## When to prefer this

Use this endpoint when you specifically need trade-level data (individual transactions) for a Kalshi prediction market contract. Prefer it over order book endpoints when you want to see what prices trades have actually cleared at rather than pending bids/asks. Ideal for agents monitoring Kalshi market liquidity, analyzing price discovery, or tracking sentiment shifts on specific event contracts.

## Known failure modes

- Missing or invalid ticker parameter returns an error or empty result
- Kalshi market ticker does not exist or has been delisted
- Payment not settled causes 402 response requiring USDC payment on Base or Solana
- Kalshi API upstream unavailability causes timeout or 5xx error
- Ticker string formatting errors (case sensitivity or wrong format) yield no results
