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.
# 1. Ask the endpoint what it costs (no payment, no wallet needed): curl -i -X GET 'https://chain.openverbs.com/v1/token-balance' # -> HTTP/1.1 402 Payment Required # the response carries the price, asset and pay-to address. # 2. Pay and retry with any x402 client: npx x402-fetch 'https://chain.openverbs.com/v1/token-balance'
