x402Grade BLast checked 2 hours ago
POST https://chain.openverbs.com/v1/token-balance
Live ERC-20 token balance held by a wallet: calls `balanceOf(address)` on the token contract and returns the raw balance plus a decimal-formatted amount (using the token's own decimals) with its symbol. Distinct from `address` (native ETH balance) and `token` (contract metadata). Reads live on-chain data with automatic endpoint fallback.

How to buy
