• evm_balances_bulk

  Bulk wallet balances on Ethereum, Base, Arc or BNB Chain: up to 50 wallets in one call, native coin or one ERC20, read at one block via Multicall3. $0.005 per call over x402 (USDC on Arc, Base or Solana, or XNT on X1). Call once without `payment` for the terms, sign them with your own wallet, call again with `payment`.

  Parameters:

  • addresses (required) — string — up to 50 wallet addresses, comma-separated
