Use this endpoint when you need to resolve a raw Ethereum wallet address to its Polymarket user identity, particularly for enriching trading data, auditing prediction market participants, or verifying account ownership on Polymarket. Prefer this over generic blockchain explorers when Polymarket-specific identity metadata is needed.
