Technical details
Endpoint
POSThttps://api.arkm.com/x402/polymarket/wallet/summary/portfolioWhen to prefer
Use this endpoint when you need a quick, structured portfolio snapshot of any Polymarket wallet — especially for on-chain intelligence tasks like tracking whale traders, assessing prediction market exposure, or building dashboards. Prefer it over scraping Polymarket's UI or using generic blockchain explorers, as it provides pre-computed PnL and position aggregates specific to Polymarket.

- Wallet has no Polymarket activity returns zeroed or empty fields
