## When to prefer this

Use this endpoint when you need a breakdown of Polymarket trading activity segmented by trader persona and position side for a specific market. It is ideal for understanding who is trading what, detecting smart-money signals, or performing due diligence before entering a market. Prefer this over raw blockchain data when you want pre-computed persona segmentation rather than raw wallet addresses.

## Known failure modes

- Invalid or unknown market ID (var1) returns an error or empty result
- Stale data: results reflect ~24h lag so very recent trades are not included
- Payment failure if USDC balance is insufficient for the $0.10 x402 payment
- Market not yet indexed or too new to have persona-segmented data
- Rate limiting if the same wallet calls repeatedly without adequate balance
