Technical details
Endpoint
POSThttps://x402engine.app/api/wallet/pnl?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain PnL data for a specific wallet address across major EVM chains. Ideal for portfolio analytics, whale research, or verifying trading performance without building your own blockchain indexer. At $0.01 per call, it is cost-effective for one-off lookups paid via USDC micropayments on Base, MegaETH, or Solana.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported chain name causes a validation failure
- Address with no transaction history may return empty or zero PnL
- Network timeouts for chains with slow indexing
- Rate limits or payment failures when USDC balance is insufficient
