# Base Network Address Inspector

> Base Network Address Inspector is a paid API for AI agents from manylives.me, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-13).

Looks up detailed metadata for any address on the Base network, including whether it's a wallet or contract, proxy/implementation info, token standard, name, symbol, owner, nonce, and balances.

## Facts

- Endpoint: GET https://manylives.me/paid/chain/address?utm_source=zero.xyz
- Price: $0.003/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/base-network-address-inspector-9d471fcc
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_CCXIl-ZGfsSvTKfYi-4Ne

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability base-network-address-inspector-9d471fcc
```

Example prompt: What exactly is the Base address 0x4200000000000000000000000000000000000006 — is it a wallet or contract, and if it's a token what's its name, symbol, and standard?

## When to prefer this

Choose this endpoint when you need comprehensive on-chain metadata about a Base network address in a single call — combining wallet/contract classification, proxy detection, token standard identification, and balance lookup without requiring your own Base RPC node or multiple separate queries.

## Known failure modes

- Invalid or malformed 0x address returns an error
- Address not found on Base network (e.g. not yet deployed)
- Network timeout or RPC unavailability
- Non-Base-network address passed — endpoint only covers Base
- Payment not received or insufficient USDC balance for x402 access

## How this service works

What is this Base network address? Wallet or contract, bytecode size, upgradeable proxy and implementation, token standard (ERC-20, ERC-721, ERC-1155) with name and symbol, owner, nonce and balances.

## Output

Returns a JSON object containing: address kind (wallet or contract), bytecode size in bytes, whether it is a proxy, token standard (ERC-20, ERC-721, ERC-1155, or null), token name and symbol, owner address, nonce, ETH balance, and USD stablecoin balance.
