## What it does

Pay-per-call MCP tool for treasury, payout-verification and counterparty-triage agents: balanceOf for ANY ERC-20 on Base mainnet \(defaults to USDC\), resolved through the token contract itself so you get symbol, decimals and both raw and human-readable balance in one call — no ABI handling, no decimals guessing. Settlement-honest: a bad address or a non-contract token returns =400 so x402 settles nothing and you are never billed for a missing answer. Tool: erc20\_balance.

## How to buy

```text
PAID ($0.002/call). This listing's endpoint did not answer FiatDock's last check (last checked 2026-10-25T12:49:30.433Z), so it may be asleep or gone — but that check can be hours old, and free hosts wake on the first request. Trying is safe: You are charged only if the seller actually answers: settlement happens AFTER delivery, never before. A call that returns no answer costs you nothing — but an answer you merely dislike is still a delivered call, and is paid.
