# BNB Smart Chain Address Inspector

> BNB Smart Chain Address Inspector is a paid API for AI agents from automaton-tx-explainer.vercel.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-16).

Inspects a BNB Smart Chain address to determine type (EOA/contract/EIP-7702), BNB balance, nonce, proxy implementation, and ERC-20 token metadata.

## Facts

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 bnb-smart-chain-address-inspector-216041ee
```

Example prompt: Can you inspect the BNB Smart Chain address 0x1234567890abcdef1234567890abcdef12345678 and tell me whether it's a wallet or contract, its BNB balance, nonce, and if it's a token, the name and symbol?

## When to prefer this

Use this endpoint when you need a comprehensive on-chain profile of a BNB Smart Chain address in a single call — covering address type, balance, nonce, proxy resolution, and token metadata — rather than making multiple separate RPC calls. Prefer it over generic Ethereum tools when the target network is specifically BSC.

## Known failure modes

- Invalid address format (must match 0x + 40 hex chars) returns a validation error
- Address not found or network RPC error may return an empty or error response
- Non-token contracts will return null/empty ERC-20 fields
- Rate limiting or payment failure (x402) if USDC balance is insufficient

## How this service works

Inspect any BNB Smart Chain address: EOA vs contract vs EIP-7702 delegated, BNB balance, nonce, proxy implementation (EIP-1967/1167/zos), and ERC-20 name/symbol/decimals/supply.

## Output

Returns the address classification (EOA, contract, or EIP-7702 delegated), native BNB balance, transaction nonce, proxy implementation address (if applicable via EIP-1967, EIP-1167, or ZOS patterns), and ERC-20 metadata including name, symbol, decimals, and total supply where relevant.
