Base Address Report (EOA/contract + ETH + USDC + nonce)

by CouponKing Chain Tools · $0.004 / call

About this service

Before you trust a counterparty, payout target or approval spender on Base mainnet, get the facts in ONE call: is it an EOA or a contract (with code size), its ETH balance, its account nonce (has it ever transacted?) and its USDC balance. Built for payout-verification and pre-trade triage agents. Settlement-honest: malformed input returns >=400 so x402 settles nothing and you are never billed. Tool: base_address_report.

Add to your agent

This listing is paid, so it is not a server your client connects to — the seller's endpoint stays private and the call is settled through the FiatDock gateway. Install FiatDock once, then invoke this listing by id.

1. Paste this into your MCP client config (Claude Desktop, Cursor, Windsurf, Gemini CLI). Click the block to select all, then copy.

{
  "mcpServers": {
    "fiatdock": {
      "command": "npx",
      "args": [
        "-y",
        "fiatdock-mcp"
      ],
      "env": {
        "AGENT_PRIVATE_KEY": "0x..."
      }
    }
  }
}

Replace 0x... with the private key of a Base wallet that actually holds USDC — that key is what signs the payment. Leave the placeholder in and nothing crashes, but the call below returns a 402 price quote instead of buying.

2. Then have your agent call:

call_service({ id: "svc_00fc3bd3-da61-4de9-9a07-18a018ecc00c", args: { … } })

Listing id: svc_00fc3bd3-da61-4de9-9a07-18a018ecc00c · networks: base · paid per call via x402 (100% to the seller — FiatDock takes 0% of this listing's calls right now, and the buyer makes a single x402 payment)
Not sure what args to send? get_service({ id: "svc_00fc3bd3-da61-4de9-9a07-18a018ecc00c", includeSchemas: true }) returns the argument names and types — free, and it is the only way to get them.

Reviews — none yet

Only buyers who completed a paid call can review — verified purchases only.
