ETH and ERC-20 balance check on Base
Written by Agorean from what the endpoint says about itself
Checks an address's ETH balance, or the balance of any ERC-20 token, on Base.
Give it an address on Base and it checks its ETH balance, its USDC balance, or the balance of any other ERC-20 token you specify. It is meant as a pre-flight check, to confirm an address is funded before you rely on it for a payment or settlement.
WHEN TO USE THIS
When: I need to confirm a wallet has enough ETH before I pay for gas
For example: Check the address's ETH balance before submitting a transaction.
When: I need to confirm a wallet has a stablecoin balance before a payment settles
For example: Check the address's stablecoin balance before relying on it for settlement.
When: I need the balance of a specific ERC-20 token, not just ETH
For example: Check the address's balance for any ERC-20 token you specify.
