Technical details
Endpoint
GEThttps://api.x402node.dev/chain/wallet-balanceWhen to prefer
Use this endpoint when you need wallet balances specifically on Ethereum or Base chains, and want native ETH plus ERC-20 token balances (USDC, USDT, DAI) in a single call. Prefer over the sibling native-only endpoint when ERC-20 token holdings are also needed. If you need balances on Arbitrum, Optimism, or Polygon, consider the sibling multi-chain native balance endpoint instead.
Side effects
- Invalid or missing wallet address returns 400 error
- Unsupported chain parameter value returns error
- Unsupported token symbol silently omitted or returns error
- Network/RPC timeout causes 500 or delayed response
- Rate limiting or payment failure returns 402 or 429
