Endpoint
POSThttps://api.arkm.com/x402/polymarket/wallet/event-historyWhen to prefer
Use this endpoint when you need historical on-chain event data specifically for a wallet's Polymarket activity, as indexed and labeled by Arkham Intelligence. Prefer this over generic blockchain explorers when you want Arkham's entity labeling and intelligence layer applied to Polymarket-specific events. Best suited for forensic analysis, due diligence on prediction market participants, or auditing wallet behavior on Polymarket.
Side effects
- Invalid or malformed wallet address returns an error response
- Wallet address with no Polymarket activity returns empty event list
- Rate limiting or authentication failure if API credentials are missing or invalid
- Network timeout for wallets with extremely large event histories
- Unsupported address format (e.g. non-EVM address) may return an error
