Technical details
Endpoint
POSThttps://api.arkm.com/x402/polymarket/pnl/chartWhen to prefer
Use this endpoint when you need granular time-series PnL performance data for a specific Polymarket wallet address, especially when cumulative position sizing and USDC flow history over custom time windows matter. Prefer this over general wallet analytics when the focus is specifically on Polymarket prediction market trading performance rather than broader on-chain activity.
Side effects
- Invalid or unrecognized wallet address returns empty or error response
- Insufficient USDC balance for x402 pay-per-request payment causes request rejection
- Invalid time interval or malformed date range returns error
- Wallet address with no Polymarket activity returns empty points array
- Rate limiting or payment processing failure from x402 layer
