## What it does

A pay-per-call MCP tool that enriches any Base address in ONE call before an agent trusts it: EOA vs contract \(and whether it's an ERC-20, with name/symbol/decimals\), account nonce, ETH + USDC balance, and a keyless GoPlus security verdict \(phishing / sanctioned / mixer / money-laundering / blacklist and more\). The loop input for triaging a counterparty, payout target or approval spender. Tool: address\_intel — 0.0045 USDC/call via x402 \(paid automatically by the fiatdock-mcp package\). A bad address returns 400 and an RPC/GoPlus outage 502 — neither is charged. Non-custodial; read-only; Base-only.

## How to buy

```text
PAID ($0.0045/call via x402, first-party): call_service({ id: "svc_becf784b-06a0-48e7-9d4a-6d3e4f2c5b81", args }) forwards to https://fiatdock.com/mcp, which answers HTTP 402 until paid. NOTE priceUsd is 0 only because this listing is not gateway-routed — budget from x402PriceUsd. The fiatdock-mcp npm package (AGENT_PRIVATE_KEY) pays automatically; this remote /mcp surfaces the 402 challenge.
