## 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 mekong-trade-intel-base-chain-state-reader-a5d00d11
```

Example prompt: What's the ETH balance and ENS name for the Base address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045, and is it a contract or a regular wallet?

## When to prefer this

Choose this endpoint when you need live Base chain state (balance, block, contract type, ENS) for a specific address without setting up an account or API key — ideal for lightweight, pay-per-call agent workflows on the Base L2 network. Prefer it over Ethereum mainnet RPC wrappers when your target address is on Base specifically.

## Known failure modes

- Invalid or malformed address (not 0x-prefixed or not 40 hex chars) returns an error
- Address not found on Base returns zero balance and no ENS name
- Network congestion may cause delayed or stale block data
- ENS resolution may return null if no name is registered
- Payment failure (insufficient USDC balance) blocks the call under x402 protocol

## How this service works

Read live Base chain state for any address: ETH balance, latest block, contract/EOA check, ENS name. $0.002 per call. No account or API key needed.

## Output

Returns live Base chain data for the queried address: ETH balance (in wei or ETH), the latest block number at time of query, a flag indicating whether the address is a smart contract or an EOA (externally owned account), and the ENS name associated with the address if one exists.
