One call, either direction: pass a trading wallet to get its username, controlling EOA, wallet type, deployment status, current status, and related wallets — or pass an EOA to list every Polymarket wallet that account controls. wallet_type tells you what kind of wallet an address is. deployed tells you whether its contract exists on Polygon. current tells you whether it is the account’s selected trading-wallet address. When matched by wallet, wallet_details includes that address, the current address, and other deployed wallet types associated with the same EOA.
